Microbial Ecology of Activated Sludge Book Review:

"Microbial Ecology of Activated Sludge, written for both microbiologists and engineers, critically reviews our current understanding of the microbiology of activated sludge, the most commonly used process for treating both domestic and industrial wastes.The contributors are all internationally recognized as leading research workers in activated sludge microbiology, and all have made valuable contributions to our present understanding of the process. The book pays particular attention to how the application of molecular methods has changed our perceptions of the identity of the filamentous bacteria causing the operational disorders of bulking and foaming, and the bacteria responsible for nitrification and denitrification and phosphorus accumulation in nutrient removal processes. Special attention is given to how it is now becoming possible to relate the composition of the community of microbes present in activated sludge, and the in situ function of individual populations there, and how such information might be used to manage and control these systems better. Detailed descriptions of some of these molecular methods are provided to allow newcomers to this field of study an opportunity to apply them in their research. Comprehensive descriptions of organisms of interest and importance are also given, together with high quality photos of activated sludge microbes."--Publisher's description.

The Link Between Denitrifying Ecology Environmental Conditions and Nitrous Oxide Production in Wastewater Treatment Book Review:

Nitrous oxide (N2O) is a potent greenhouse gas and ozone-depleting compound known to be emitted from wastewater treatment. Emissions of N2O results from the activity of the microorganisms employed in the transformation of reactive nitrogen species (NOx). N2O emissions from wastewater treatment are currently underestimated by United Nations (UN) and the United States (US) Environmental Protection Agency (EPA) guidelines, and treatment plants show differing rates of N2O emissions. Improving our understanding of the mechanisms that drive N2O production and subsequent emissions are essential for its mitigation. N2O is produced by a variety of microbial metabolic pathways; this thesis primarily focuses on N2O production via the denitrification pathway. Denitrification, conducted by heterotrophic bacteria is the Dissimilatory reduction of nitrogen oxides such as nitrate (NO3-) or nitrite (NO2-) to di-nitrogen gas (N2), using carbon as electron donors. The process occurs in a cascade reducing NO3-, to NO2-, nitric oxide (NO), N2O and finally N2. This process is catalyzed by several enzymes including, nitrate reductase (Nar, and Nap), nitrite reductase (Nir) nitric oxide reductase (Nor) and nitrous oxide reductase (NosZ). Denitrification is a widespread trait, and the pathway is encoded by a variety of genes, which produce functionally equivalent enzymes but form differing denitrifying phylogenies. For example, nitrite reductase is encoded by nirS and nirK the genes for the cytochrome-cd1 and copper-based dissimilatory nitrite reductases, respectively, while nitrous oxide reductase is encoded by either the truncated or non-truncated gene nosZII or nosZI respectively. It has been proposed that differences in the microbial population may explain the difference in N2O emission observed between treatment plants. This hypothesis is supported by the recent discovery of non-denitrifying N2O reducing organisms encoded by the gene nosZII. These organisms lack the preceding enzymes of the denitrifying pathway but retain the ability to reduce N2O, they have a high abundance in soils, and nosZII abundance shows a strong correlation with reduced N2O emissions. The understanding of denitrifying microbial ecology and its role in the production of N2O from wastewater treatment is currently limited. The primary aim of this thesis is to address the hypothesis: Denitrifying ecology determines the magnitude and rate of N2O accumulation in Wastewater treatment plant (WWTP) sludge. To address this hypothesis, a stepwise approach has been taken. 1) A survey of the microbial ecology of three New Zealand (NZ) WWTPs was conducted to determine denitrifying ecology by the distribution of denitrifying functional markers (nirS, nirK, nosZI, and nosZII) within each population. The following hypotheses were tested, a) denitrifying populations will differ between WWTPs, and b) Wastewater is a disadvantageous environment for non-denitrifying organisms (nosZII), and they will be under-represented. 2) Using the sludges from the surveyed WWTPs, sludge metabolism was examined under ideal denitrifying conditions for differences in NOx profiles including N2O accumulation. Accumulation of NOx intermediaries was correlated with the relative abundance of denitrifying functional markers, testing the hypotheses c) differing denitrifying populations accumulate different amounts of N2O, and d) N2O accumulation will correlate with non-denitrifying organism abundance. 3) As wastewater treatment plants are not stable environments and can suffer from process perturbations, sludges with now known populations, and NOx profiles under control conditions, were exposed to environmental shocks (pH and nitrite (NO2-). Testing the hypothesis: e) Within a specific range of environmental shock, denitrifying population structure will determine N2O accumulation. Survey of NZ microbial populations supports the hypotheses, showing differing total microbial and denitrifying populations, with low abundance of non-denitrifying N2O reducing organisms(nosZII). Analysis of the relative abundance of denitrifying functional markers suggests NZ WWTPs have a genetic predisposition to N2O emissions. Additional findings include the identification of co-occurring nirK and nirS in the same organisms in each treatment plant and the observation that NZ treatment plants show the opposite trend to most of the literature reports with a markedly dominant nirK over nirS population. Examination of the NOx profiles of the three sludges under ideal denitrifying conditions supports the hypotheses showing differing N2O accumulation in each sludge and increasing abundance of nosZII correlating with a decrease in the maximum N2O concentration. All sludges acclimatized to laboratory conditions quickly accumulating minimal N2O after just four sequence batch cycles. Analysis of changes in the rate of NO3- reduction and the Max N2O accumulation suggests that under stable conditions N2O accumulation will be minimal. Examination of the population's response to environmental shock supports the hypothesis, with different populations accumulating N2O when exposed to different environmental shocks. No population was susceptible to N2O accumulation under all conditions. Populations that exhibited NO2- accumulation were resistant to NO2- shock but more susceptible to changes in pH, while populations exhibiting minimal NO2- accumulation were sensitive to NO2- shock but more resistant to changes in PH accumulation. This research concludes that denitrifying microbial populations determine the accumulation of N2O in response to changes in environmental conditions. Denitrifying populations differ between WWTPs. However, results suggest, irrespective of the denitrifying microbial population's structure, stable conditions will result in minimal N2O accumulation. When exposed to environmental shock differing populations showed susceptibility to accumulated N2O under differing environmental conditions. These results suggest that management of N2O accumulation and subsequent emissions will need to be on a case by case basis. Emissions may be addressed by the introduction of a microbial population less susceptible to the N2O accumulation under the environmental conditions of a given treatment plant. Further research is required to test the feasibility of this management strategy.

Disturbance performance diversity Relationships and Microbial Ecology in Bioreactors for Wastewater Treatment Book Review:

Biological wastewater treatment plays a major role in the protection of water quality and public health. Wastewater also constitutes a renewable source of freshwater in urban centres with scarce water supplies. Improving the stability and performance of wastewater treatment processes is a main focus of environmental engineering and biotechnology, to help achieve the sustainable development goal of guaranteeing availability and perdurability of water and sanitation for everyone. Microbial communities in bioreactors are responsible for the removal of organic carbon and nutrients. Disturbance is deemed a main factor affecting the stability of microbial community assembly and function, but a predictive understanding of its outcomes remains unclear. Several relevant aspects are currently under debate including whether disturbance can lead to reproducible or variable states of function and microbial composition, whether a more diverse community implies a better ecosystem performance, what drives the balance between stochastic and deterministic mechanisms of community assembly, and how pulses versus sustained perturbations affect microbial community structure and performance. Additionally, trait-based approaches from community ecology offer a way to find general rules to understand the mechanisms driving changes in community assembly and function under perturbations, but their applicability to microbial ecology and environmental biotechnology has only been suggested so far. This dissertation aims to integrate the concepts of disturbance-diversity-performance in sludge bioreactors from an interdisciplinary perspective involving the fields of engineering, molecular biology, ecology and statistics. The goals of this research were to (1) study the effect of defined disturbance events on bioreactor community assembly; (2) investigate the effect of disturbances on key functions for process performance in bioreactors; (3) examine temporal dynamics of sludge bacterial communities under succession; and (4) incorporate frameworks from ecological theory to aid in the understanding of these three prior objectives, with the additional potential of making its findings useful for studies across other complex microbial communities. To address these goals, controlled experiments using activated sludge bioreactors (inoculated from a full-scale facility) and different disturbance agents were designed and performed at different scales of volume, time and replication. For all studies, variations in ecosystem function were tracked, while a combination of distance-based multivariate tests and ordination methods, alpha-diversity indices, general linear multivariate models, and null model analysis from ecology, was employed to evaluate changes in microbial community structure. The first study involved a 35-day microcosm experiment using 24 replicated wastewater bioreactors subjected to a range of different disturbance frequencies in the form of toxic 3-chloroaniline. A stronger temporal decrease in alpha-diversity at the extreme, undisturbed and press-disturbed, sides of the disturbance range led to an intermediate disturbance hypothesis (IDH) pattern, with the highest diversity found at intermediate levels of disturbance. Undisturbed and press-disturbed levels displayed the highest community and functional similarity across replicates, suggesting deterministic processes dominating. The opposite was observed amongst intermediately disturbed levels, implying stronger stochastic assembly mechanisms. Tradeoffs were observed in community function between organic carbon removal and both nitrification and biomass productivity, as well as between diversity and function, hence not every ecosystem function was favoured by higher community diversity. The second study employed trait-based frameworks from ecology to enhance the understanding of the response of this complex microbial system after 35 days of succession under a disturbance gradient. The concept of ‘community aggregated traits’ was incorporated to assess ecosystem function parameters and to identify ‘trait complexes’ from the genotypic information gathered from the metagenomics dataset. Different community-level life-history strategies were associated across the disturbance range, with competitors (C) at the undisturbed level and stress-tolerants (S) at the press-disturbed level, while intermediate levels of disturbance harboured ruderal (R) strategies. Such three-way CSR strategies were proposed in the lights of trade-offs in community function and genotypic potential, and changes in bacterial genera composition. The third study tested the effect of a non-toxic sustained variation in organic loading, involving two sets of four replicate mesocosm reactors that were operated at two different food to biomass (F:M) (0.19 and 0.36) and carbon to nitrogen (C:N) (3.5 and 6.3) ratios for a period of 127 days, including 53 days of sludge acclimation. The results showed that disturbed reactors with high F:M and C:N ratios exhibited different ecosystem function, community and genotypic assembly compared to the control reactors. Treatment reactors displayed quantifiable and initially variable functional resistance. Despite displaying higher taxonomic alpha-diversity, these reactors exhibited partial inhibition of nitrification, showing that higher diversity did not translate into better functionality. Deterministic assembly mechanisms for bacterial genera were stronger for disturbed reactors, while stochastic assembly was more important among rare (

Reexamining the Engineered Nitrogen Cycle Book Review:

Biological wastewater treatment is a multi-billion dollar industry--the largest application of biotechnology in the world. Nitrification systems in these wastewater treatment plants are critically important barriers to nitrogen pollution, thereby protecting natural systems from ammonium toxicity, excess emissions of the potent greenhouse gas nitrous oxide, nitrogenous oxygen demand, and N-stimulated eutrophication. Despite the environmental and economic importance of these processes, surprisingly little is known about the nature of the key biocatalysts (microbial communities) within nitrifying wastewater treatment bioreactors. The body of research presented in this dissertation targets three knowledge gaps in the microbial ecology of biological nutrient removal systems: microbial community dynamics and associated deterministic drivers; microbial diversity--namely, the 'core' and 'dispensable' microbiome in activated sludge and the relative importance therein of different groupings of ammonia-oxidizing microorganisms to nitrogen transformations; and the importance of microbial immigration in structuring engineered microbial communities. In Chapter 2, I investigate the diversity, population dynamics, and relative importance of two key types of microorganisms in nitrogen removal processes--ammonia-oxidizing bacteria (AOB) and newly-discovered ammonia-oxidizing archaea (AOA)--in a one-year time series of weekly activated sludge samples from a nitrifying wastewater treatment plant in California. I demonstrate that AOB predominate by 3 orders of magnitude over AOA in this system--an important result, given recent reports of natural environments dominated by AOA, and the first quantitative comparison of AOA and AOB in activated sludge. Moreover, my results reveal a predominance in the AOB community of a novel Nitrosomonas-like lineage and strong associations between AOB community dynamics and temperature, dissolved oxygen, influent nitrite concentrations, and primary influent chromium concentrations. In Chapter 3, I employ molecular fingerprinting analyses (T-RFLP) to characterize overall bacterial dynamics in activated sludge over the same one-year time period and to test a fundamental prediction of macroecological theory--the "Species-Time Curve"--In engineered microbial systems. My results reveal surprisingly strong long-term temporal dynamics in the activated sludge bacterial assemblage during a period of stable performance, with a gradual succession away from initial conditions likely linked to variations in dissolved oxygen, temperature, influent silver, biomass levels, and influent nitrite concentrations. I also provide significant support for a power-law taxa-time relationship (TTR) in activated sludge systems, as predicted by macroecological theory, with a power-law exponent (w=0.209) well in-line with those observed in macrobial systems. In Chapter 4, I detail an astonishingly high reservoir of overall microbial phylogenetic and functional diversity and unexpectedly large community dynamics in activated sludge via application of cutting-edge phylogenetic (PhyloChip) and functional gene (GeoChip) microarrays. While nearly 2,500 distinct microbial taxa distributed throughout 48 bacterial and archaeal phyla were observed in 12 monthly samples from a full-scale wastewater treatment bioreactor, the set of taxa that were present in all samples--the "core" microbiome--was limited to ~700 taxa. Dynamics in the ~1800 taxa present in only a subset of samples--the "dispensable" microbiome--were significantly associated with temperature and influent nitrite. Of 10,267 unique functional genes in 266 gene families that showed statistically significant hybridization signals to our functional gene microarray platform, only 66 unique functional genes were detected in all samples. In contrast, representatives from 63% of detected functional gene families were present in all samples. This core functional gene set encoded for resistance to several metals, specific organic degradation functions, cellulose degradation, nitrification, denitrification, and, surprisingly, sulfate reduction and methanogenesis. This first examination of the core and dispensable microbiome in an activated sludge bioreactor suggests that activated sludge microbial communities are functionally and phylogenetically highly diverse, but that only a fraction of this diversity constitutes a true core microbiome. In Chapter 5, I resolve a puzzling connection in Chapters 2-4 between microbial community dynamics and small levels of nitrite in the bioreactor influent by demonstrating intra-plant microbial immigration between coupled process units at a full-scale wastewater treatment plant. I provide converging lines of retrospective and prospective evidence that these microbial immigrants may be significant drivers of microbial community dynamics in engineered systems. Quantitative PCR (qPCR) analyses demonstrated accumulation of AOB in a BOD--removal trickling filter and significant immigration to a downstream activated sludge bioreactor. T-RFLP analyses corroborated by clone libraries showed that Nitrosomonas europaea dominated the trickling filter, while a 'Nitrosomonas-like' lineage dominated in activated sludge. N. europaea was previously shown to predominate in activated sludge during elevated bioreactor influent NO2- events, strongly suggesting that activated sludge AOB community dynamics are driven in part by immigration via sloughing from the upstream trickling filter. High-density phylogenetic microarray (PhyloChip) analyses revealed an overabundance of methanogens in the trickling filter relative to the activated sludge bioreactor and demonstrated transport of a diverse heterotrophic assemblage to the activated sludge via the trickling filter effluent. Our results indicate that immigration may play an unexpectedly significant role in the microbial community assembly process in activated sludge bioreactors, with potentially profound implications for design and operation of this widely-used, environmentally and economically important technology. Taken together, my research suggests the utility of coupling fundamental microbial ecology research to bioprocess engineering. I anticipate that, in the long term, the results of my work on bioreactor microbial ecology will lay the framework for enhanced "microbial resource management" strategies for wastewater treatment bioreactors, a critically important application of environmental biotechnology.

Cold adapted Yeasts Book Review:

Yeasts are a versatile group of eukaryotic microorganisms, exhibiting heterogeneous nutritional profiles and an extraordinary ability to survive in a wide range of natural and man-associated ecosystems, including cold habitats. Cold-adapted yeasts inhabit numerous low-temperature environments where they are subjected to seasonal or permanent cold conditions. Hence, they have evolved a number of adaptation strategies with regard to growth and reproduction, metabolic activities, survival and protection. Due to their distinctive ability to thrive successfully at low and even subzero temperatures, cold-adapted yeasts are increasingly attracting attention in basic science and industry for their enormous biotechnological potential. This book presents our current understanding of the diversity and ecology of cold-adapted yeasts in worldwide cold ecosystems, their adaptation strategies, and their biotechnological significance. Special emphasis is placed on the exploitation of cold-adapted yeasts as a source of cold-active enzymes and biopolymers, as well as their benefits for food microbiology, bioremediation and biocontrol. Further, aspects of food biodeterioration are considered.

Wastewater Treatment Book Review:

Wastewater Treatment: Molecular Tools, Techniques, and Applications provides an insight about the application of different tools and technology for exploring microbial structure-function relationships that involved in WWTPs. From the present day consequence of alarming usable water crysis throughout the globe, an immediate action on water cycle is necessary. Along with other options the waste water recycling is one major opportunity to combat the future scarcity. The book aims to provide a comprehensive view of advanced emerging technologies for wastewater treatment, heavy metal removal, pesticide degradation, dye removal, waste management, microbial transformation of environmental contaminants, etc. It also describes different application of Omic tools in Waste water treatment plants (WWTPs), describes the role of microorganisms in WWTPs, points out the reuse of treated wastewater through emerging technologies, also includes the recovery of resources from wastewater and emphasizes on cutting edge molecular tools for WWTPs. We hope the content of the book will be very much usefull for the community who are directly associated in wastewater management research, people who are associated with environmental awarness programme and the students of UG and PG courses. Features: This book highlights the importance of molecular genomics, molecular biology techniques to sort out the problems faced by industrialist who operates wastewater treatment plant with the ever-increasing number of environmental pollutants.

Development in Wastewater Treatment Research and Processes Book Review:

Removal of Emerging Contaminants from Wastewater through Bio-nanotechnology showcases profiles of the nonregulated contaminants termed as “emerging contaminants, which comprise industrial and household persistent toxic chemicals, pharmaceuticals and personal care products (PPCPs), pesticides, surfactants and surfactant residues, plasticizers and industrial additives, manufactured nanomaterials and nanoparticles, microplastics, etc. that are used extensively in everyday life. The occurrence of “emerging contaminants in wastewater, and their behavior during wastewater treatment and production of drinking water are key issues in the reuse and recycling of water resources. This book focuses on the exploitation of Nano-biotechnology inclusive of the state-of-the-art remediate strategies to degrade/detoxify/stabilize toxic and hazardous contaminants and restore contaminated sites, which is not as comprehensively discussed in the existing titles on similar topics available in the global market. In addition, it discusses the potential environmental and health hazards and ecotoxicity associated with the widespread distribution of emerging contaminants in the water bodies. It also considers the life cycle assessment (LCA) of emerging (micro)-pollutants with suitable case studies from various industrial sources. Provides natural and ecofriendly solutions to deal with the problem of pollution Details underlying mechanisms of nanotechnology-associated microbes for the removal of emerging contaminants Describes numerous successful field studies on the application of bio-nanotechnology for eco-restoration of contaminated sites Presents recent advances and challenges in bio-nanotechnology research and applications for sustainable development Provides authoritative contributions on the diverse aspects of bio-nanotechnology by world’s leading experts

Wastewater Microbiology Book Review:

Wastewater Microbiology focuses on microbial contaminants found in wastewater, methods of detection for these contaminants, and methods of cleansing water of microbial contamination. This classic reference has now been updated to focus more exclusively on issues particular to wastewater, with new information on fecal contamination and new molecular methods. The book features new methods to determine cell viability/activity in environmental samples; a new section on bacterial spores as indicators; new information covering disinfection byproducts, UV disinfection, and photoreactivation; and much more. A PowerPoint of figures from the book is available at ftp://ftp.wiley.com/public/sci_tech_med/wastewater_microbiology.
