Book Description :

"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.

Book Description :

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.

Book Description :

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.

Book Description :

The book will provide an update on our understanding of predator-prey through the prism of ecology, physiology, molecular biology, and mathematical modelling. The integration of these different perspectives while focusing on the microbial realm will highlight the importance of scale in ecological interactions, and their importance in applications. This book should thereby contribute to theoretical as well as to applied ecologists and microbiologists. Furthermore, the detailed but amenable chapters could serve as the basis of teaching advanced courses in (microbial) ecology and environmental microbiology.This work is a collection of articles that discuss microbial predation from a variety of perspectives. It provides the readers a concise resource describing factors that are critical for several different predatory microbes, including Myxobacterium spp. and Bdellovibrio-and-like organisms (BALOs), including the mechanisms involved, ecological conditions that adversely impact it and potential applications in aquaculture and bioproduction. The first half of this collection focuses more on ecological aspects of predation, with in-depth discussions on “wolf pack” predators, the presence and activities of predators in waste-water treatment plants and the role of intraguild predatory relationships, i.e., when two different predators are competing for a single prey but also interact with one another. The reader will gain a deeper understanding of the predatory mechanisms involved and their ecological roles. In the latter half, emphasis is given more to the application and limitations of predators. In addition to discussing secondary metabolite production within different microbial predators, the readers will also learn how predators are being used to purify secondary metabolites from prey. This section also discusses the expanding and promising role of predation in aquaculture, focusing on the application of predators to reduce pathogenic populations, but includes some important caveats for young researchers to consider and follow when working with Bdellovibrio. This work is written for both experienced researchers already in the field and for young scientists who are captivated by the thought of predation at the microscale and its growing importance within a wide-array of fields.

Environmental Microbiology comprises a crucial element of studies in microbiology. Enabling scientists to explore microbes in greater detail, it gives an insight into how microorganisms behave under non-simulated, natural conditions, although microbes that exist in artificial environments such as bioreactors are also studies. Exploring such processes as microbial ecology, microbially mediated nutrient cycling, geomicrobiology, microbial diversity and bioremediation the subject encompasses a great deal. Environmental Microbiology was born at the dawn of the "e;environmental era"e; at the beginning of the 1970s. Thirty years of maturation have led to an exciting and vibrant field that has attracted countless numbers of productive and enthusiastic scientists and students at universities, research centers and government agencies around the world. The present text has been designed to outline the basic and fundamental aspects of Environmental Microbiology to be understood in its right perspective. The modern techniques and designs employed in microbiological applications are discussed in a comprehensive manner which will update the readers of the commercial aspects of microbiology.
