Beschreibung
The abundance of sulfate-reducing bacteria and archaea (SRBA) is impressive and new isolates are being reported continuously. A few decades ago, only two genera of dissimilatory sulfate reducers had been identified and as of 2018, 92 genera containing more than 420 species of SRB and several species of archaea have been isolated. This book addresses the historical background of SRBA research and reviews the current status of research examining the growth of these anaerobic microorganisms. Additionally, this book covers metabolic and genomic diversity, enzymatic processes, response to stress, biocorrosion of ferrous metals, biogeochemical processes and interactions with other microorganisms in the anaerobic biosphere. It highlights the unique cellular and molecular features of these microorganisms, discusses the production and consumption of gases and reviews genomic content influencing their metabolic capabilities. Examples are provided of detoxification reactions to alleviate pollution situations, growth in in hostile environments including low nutrient availability, and the effects of sulfate-reducing bacteria (SRB) on human and animal hosts.
The abundance of sulfate-reducing bacteria and archaea (SRBA) is impressive and new isolates are being reported continuously. A few decades ago, only two genera of sulfate-reducing bacteria (SRB) had been identified. As of 2018, 92 genera containing more than 420 species of SRB have been isolated and characterized and there are several species of archaea. This book addresses the development of the research with SRBA and includes historical background of this field. Biochemical characterization of the enzymes, cytochromes and electron carriers involved with dissimilatory sulfate reduction are reviewed and the presence of relevant genes in cultured and uncultured SRBA are assessed using genome analysis. The contributions of transmembrane electron transport complexes as related to cell energetics are discussed. This book highlights the unique cellular and molecular features of the SRBA and discusses the biochemical interactions behind their metabolic capabilities which enable SRBA to grow in extreme environments. Examples are provided to detoxify and alleviate pollution situations, to evaluate mechanisms proposed for corrosion of ferrous metals and to examine the effects of SRB on human and animal hosts.
Provides a thorough overview of SRBA growth, stress response, diversity of electron donors used, and classification Covers microbial diversity, physiological adjustments and geochemical activities enabling growth in hostile environments Examines SRB growth in biofilms and mats, in deep subsurface communities, and in association with human and animal hosts
