Gases with a mixing ratio of less than one percent in the lower atmosphere (i.e. the troposphere) are considered as trace gases. Numerous of these trace gases originate from biological processes in marine and terrestrial ecosystems. These gases are of relevance for the climate as they contribute to global warming or to the troposphere’s chemical reactive system that builds the ozone layer or they impact on the stability of aerosols, greenhouse, and pollutant gases. These reactive trace gases include methane, a multitude of volatile organic compounds of biogenic origin (bVOCs) and inorganic gases such as nitrogen oxides or ozone. The regulatory function of microorganisms for trace gas cycli...
This Volume provides protocols for the biochemical analysis of hydrocarbon- and lipid-relevant products, cell components and activities of microbes that interact with hydrophobic compounds. They include methods for the extraction, purification and characterisation of surface tension-reducing bioemulsifiers and biosurfactants that increase the surface area and hence bioavailability of hydrophobic substrates. Protocols for the isolation and biochemical analysis of lipids and polyhydroxyalkanoates, food storage products made during nutrient abundance that represent important biotechnological products, are presented. The extraction of membrane lipid rafts, sub-organelles that fulfil important fu...

'If Steven Spielberg is looking for a sequal to SCHINDLER'S LIST, he could do worse than start with this book.' One key to its success is simply that each individual narrative is so well written. But there is a deeper point: the author has stepped outside the laboratory to engage with the real world. We humans may think of ourselves as the lords of creation, but Dr Dixon shows that the microbes render our tenure insecure. POWER UNSEEN is ostensibly a book about microbes. The reason it is so appealing is that, in reality, it is about ourselves'.
This book describes the structural features and properties of important types of hydrocarbons and lipids and gives an overview of their analytical characterization in biological and environmental matrices. It covers the occurrence, biosynthesis and biological functions of these compound types in diverse organisms including bacteria and archaea, algae, higher plants and arthropods. It examines their distribution in the geosphere and fundamental processes controlling the fate of fossil organic matter. Finally, it addresses important aspects of their environmental chemistry and transfer processes between different compartments of bio- and geosphere. Hydrocarbons and lipids comprise extremely diverse organic compounds that play fundamental roles in biosphere and geosphere. They represent important functional components in all living organisms and constitute a major fraction of fossil organic matter in sedimentary systems. All chapters are written by renowned experts in the respective fields.
This book explores the development of novel marine biosurfactants. The book also covers the utilization of marine surfactants for biological and biomedical, and environmental applications. Marine Surfactants: Preparations and Applications aims to examine every aspect of marine derived surfactants.The first part of the book discusses the isolation of marine surfactants from various organisms include marine bacteria, algae, cyanobacteria and so on. The editors also examine the cultivation of marine microorganisms and the harvesting of other natural biological resources from the sea. The next part of the book discusses the application marine surfactants, including oil spill removal in the sea, ...
This volume highlights recent advances that have contributed to our understanding of spatial patterns and scale issues in microbial ecology. The book brings together research conducted at a range of spatial scales (from μm to km) and in a variety of different types of environments. These topics are addressed in a quantitative manner, and a primer on statistical methods is included. In soil ecosystems, both bacteria and fungi are discussed.
