Download or read book Microbial Enzymes in Aquatic Environments written by Ryszard J. Chrost and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Extracellular Enzymes in Aquatic Environments Exploring the Link Between Genomic Potential and Biogeochemical Consequences written by Maria Montserrat Sala and published by Frontiers Media SA. This book was released on 2019-09-19 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Environmental Bioinorganic Chemistry of Aquatic Microbial Organisms written by Christel Hassler and published by Frontiers E-books. This book was released on 2013-07-05 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Bioinorganic Chemistry of Aquatic Microbial Organisms describes the interactions between metals and aquatic prokaryotic and eukaryotic microorganisms in their environment. Metals influence microbial growth in the aquatic environment as they can be either toxic to aquatic microbes, if present at too high concentrations in the environment, or limiting, if bio-essential and present at very low concentrations. In turn, microorganisms influence the biogeochemical cycling of metals as they affect trace metal concentrations, distributions between particulate and dissolved phase, and chemical speciation. At the sub cellular level, metalloproteins are the catalysts driving many steps in the biogeochemical cycles of major elements such as carbon, nitrogen and sulfur. Metals thus provide a link between the abundance and activity of enzymes, the growth of microorganisms, and the biogeochemical cycles of major climate influencing elements. Furthermore, the evolution of the chemistry of aquatic environments and atmosphere has left its mark on the microbial proteome as a direct result of changes in the solubility of metals. The aquatic microbial metallome thus has the potential to reveal information about key biogeochemical processes, their spatial and seasonal occurrence, and also to reveal how the geochemical environment is shaping the microbial population itself. The aim of this Research Topic is to highlight recent advances in our understanding of how metals influence the activity of aquatic microbes, and how microbes influence the biogeochemical cycling of metals. Applications of techniques in proteomics, spectroscopy, mass spectrometry and genomics are all leading to a greater understanding of the interactions between the microbial metallome and the “aquatic metallome” and thus the influence of metals on the biogeochemical cycles of climatically important elements such as carbon, nitrogen and sulfur. Both reviews and original research on the occurrence and abundance of microbial metal proteins and peptides, the utilisation of metals by aquatic microbes, the influence of microbially produced exudates on metal speciation and the biogeochemical cycling, and the toxicity of metals to microbial organisms are welcome.
