Book Description
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.

Book Description
The first stand-alone textbook for at least ten years on this increasingly hot topic in times of global climate change and sustainability in ecosystems. Ecological biochemistry refers to the interaction of organisms with their abiotic environment and other organisms by chemical means. Biotic and abiotic factors determine the biochemical flexibility of organisms, which otherwise easily adapt to environmental changes by altering their metabolism. Sessile plants, in particular, have evolved intricate biochemical response mechanisms to fit into a changing environment. This book covers the chemistry behind these interactions, bottom up from the atomic to the system's level. An introductory part explains the physico-chemical basis and biochemical roots of living cells, leading to secondary metabolites as crucial bridges between organisms and the respective ecosystem. The focus then shifts to the biochemical interactions of plants, fungi and bacteria within terrestrial and aquatic ecosystems with the aim of linking biochemical insights to ecological research, also in human-influenced habitats. A section is devoted to methodology, which allows network-based analyses of molecular processes underlying systems phenomena. A companion website offering an extended version of the introductory chapter on Basic Biochemical Roots is available at http://www.wiley.com/go/Krauss/Nies/EcologicalBiochemistry

Book Description
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.

Book Description
The chemistry of nickel in biological systems has been intensely investigated since the discovery of the essential role played by this transition metal in the enzyme urease, ca. 1975. Since then, several nickel-dependent enzymes have been discovered and characterized at the molecular level using structural, spectroscopic, and kinetic methods, and insight into reaction mechanisms has been elaborated using synthetic and computational models. The dual role of nickel as both an essential nutrient and as a toxin has prompted efforts to understand the molecular mechanisms of nickel toxicology and to uncover the means by which cells select nickel from among a pool of different and more readily available metal ions and thus regulate the intracellular chemistry of nickel. This latter effort highlights the importance of proteins involved in the extra- and intra-cellular sensing of nickel, the roles of nickel-selective proteins for import and export, and nickel-responsive transcription factors, all of which are important for regulating nickel homeostasis. In this Special Issue, the contributing authors have covered recent advances in many of these aspects of nickel biochemistry, including toxicology, bacterial pathogenesis, carcinogenesis, computational and synthetic models, nickel trafficking proteins, and enzymology.

Book Description
This book provides a detailed examination of the concentration, form and cycling of trace metals and metalloids through the aquatic biosphere, and has sections dealing with the atmosphere, the ocean, lakes and rivers. It discusses exchanges at the water interface (air/water and sediment/water) and the major drivers of the cycling, concentration and form of trace metals in aquatic systems. The initial chapters focus on the fundamental principles and modelling approaches needed to understand metal concentration, speciation and fate in the aquatic environment, while the later chapters focus on specific environments, with case studies and research highlights. Specific examples deal with metals that are of particular scientific interest, such as mercury, iron, arsenic and zinc, and the book deals with both pollutant and required (nutrient) metals and metalloids. The underlying chemical principles controlling toxicity and bioavailability of these elements to microorganisms and to the aquatic food chain are also discussed. Readership: Graduate students studying environmental chemistry and related topics, as well as scientists and managers interested in the cycling of trace substances in aqueous systems Additional resources for this book can be found at: www.wiley.com/go/mason/tracemetals.
