Organic matter in aquatic environments consists mostly of large compounds which cannot be taken up and utilized directly by microbial cells. Prior to incorporation, polymeric materials undergo degradation by cell-bound and extracellular enzymes produced by these microbes; in fact, such enzymatic mobilization and transformation is the key process which regulates the turnover of organic as well as inorganic compounds in aquatic environments. This volume brings together studies on enzymatic degradation processes from disciplines as diverse as water and sediment research, bacterial and algal aquatic ecophysiology, eutrophication, and nutrient cycling and biogeochemistry, in both freshwater and marine ecosystems. Its scope extends from fundamental research exploring the contribution of microbial enzymatic processes to whole ecosystem functioning to practical applications in water biotechnology. The first comprehensive publication providing an overview of this emerging field of enzymology, Microbial Enzymes in Aquatic Environments will be of great interest to ecologists and microbiologists alike.

Microbial extracellular enzymes are fundamental to the cycling of elements in aquatic systems. The regulation of these enzymatic reactions in oceans, lakes and streams is under complex multiple control by environmental factors and the metabolic capacities of different taxa and communities. While the environmental control of enzyme-mediated processes has been investigated for over 100 years, in recent years tremendous progress in techniques to characterize the metabolic potential of microbial communities (“omics” techniques) has been made, such as high-throughput sequencing and new analytical algorithms. This book explores the controls, activities, and biogeochemical consequences of enzymes in aquatic environments. It brings together experimental studies and fieldwork conducted with natural microbial communities in marine and freshwater ecosystems as well as physiological, biochemical and molecular studies on microbial communities in these environments, or species isolated from them. Additionally, the book contributes to the ongoing debate on the impact of anthropogenic climate change and pollution on microbes, extracellular enzymes and substrate turnover.

The need to understand the biological processes that are important for essential aquatic and terrestrial ecosystem function has prompted much research into the field of ecological enzymology. This book presents the two broad areas of application in a compilation of reviews by 21 international experts in their respective fields. The first explores enzymatic activities to assess the processes or mechanisms that operate in a given system, such as the rhizosphere, plant leaves and shoots, soil surfaces, and biofilms. The second considers enzymes or microbial cells as sensors to detect microbial activity and stresses due to pollution, management, or climatic change in both aquatic and terrestrial ecosystems.

Aquatic microbial ecology, a growing interdisciplinary field, has become increasingly compartmentalized in recent years. The aim of this volume is to propose a framework for biochemical and molecular approaches, which are employed ever more widely in studies of aquatic microbial communities and ecosystem functioning. The book presents state of the art applications of modern molecular research techniques to a range of topics in ectoenzymes microbial carbon metabolism bacterial population dynamics RNA chemotaxonomy of microbial communities plasmids and adaptation to environmental conditions. Written for limnologists, marine biologists, and all researchers interested in environmental microbiology and molecular aspects of ecology, this volume will provide a stimulating introduction to this emerging field.

Microorganisms for Sustainable Environment and Health covers hazardous pollutants released from natural as well as anthropogenic activities and implications on environmental and human health. This book serves as a valuable source of basic knowledge and recent developments in the clean technologies and pollution-associated diseases and abnormalities in the context of microorganisms. Focused on current solutions to various environmental problems in the field of bioremediation, it provides a detailed knowledge on the various types of toxic environmental pollutants discharged from different sources, their toxicological effects in environments, humans, animals and plants as well as their biodegradation and bioremediation approaches. This book helps environmental scientists and microbiologists learn about existing environmental problems and suggests ways to control or contain their effects by employing various treatment approaches. - Provides information on waste treatment approaches using microbes - Includes applications in biofuel and bioenergy production - Covers green belt development, hydroponics, phytoremediation, wetland treatment technology, and common effluent treatment plants (CETPs) - Discusses dissemination of antibiotic resistance among pathogenic microbes and strategies to combat multi-drug resistance (MDR)

This book shows how the biological transport, bioaccumulation, disposition, and toxicity of polycyclic aromatic hydrocarbons (PAH) in the aquatic environment are influenced by the ability or inability of organisms to metabolize these environmental pollutants. Written by leading scientists in the fields of PAH metabolism and toxicity in both aquatic and mammalian systems, this book discusses recent advances in the areas of PAH biogeochemistry and bioaccumulation, microbial degradation, enzymes of activation, and detoxication, metabolism of PAH, and laboratory and field studies on carcinogenic/toxic effects. Additionally, important similarities and differences in metabolism of PAH by aquatic and terrestrial organisms are featured. The discussion of bioavailability, metabolism, and subsequent toxic effects should aid in the assessment of the ecological consequences of PAH in the aquatic environment.
