Bacterial Energetics

Bacterial Energetics deals with bacterial energetics and the molecular basis of how ions move between and within energy-transducing molecules. Topics covered range from respiration-driven proton pumps and primary sodium pumps to light-driven primary ionic pumps, bacterial transport ATPases, and bacterial photosynthesis. Sodium-coupled cotransport and ion-exchange systems in prokaryotes are also considered. This volume is comprised of 17 chapters and begins with an analysis of the pumps and processes that establish electrochemical ion gradients across bacterial membranes, followed by a discussion on the major types of bioenergetic work that utilize these gradients. The energetics of periplasmic transport systems, chemolithotrophs, methanogens, and protein insertion and translocation into or across membranes are also examined, along with bioenergetics in extreme environments such as high-pressure and high-temperature environments; energetic problems of bacterial fermentations; energetics of bacterial motility; and energetics of the bacterial phosphotransferase system in sugar transport and the regulation of carbon metabolism. This book should be of interest to molecular biologists and biochemists.

Applies thermodynamics to the analysis of microbial growth and shows how it can be used for a precise analysis of the energetics of the growth process. Describes the development of theories on the energy changes that accompany microbial growth. Beginning with a review of the thermodynamic principles, the text approaches the description of microbial growth and energy changes historically and charts the progress from the fields' earliest beginnings to the present. Provides a useful perspective to theories about the evolution of life.

Bacterial Metabolism focuses on metabolic events that occur in microorganisms, as well as photosynthesis, oxidation, polysaccharide formation, and homofermentation. The book first discusses the thermodynamics of biological reactions, photosynthesis and photometabolism, and chemosynthesis. Free energy, photosynthesis, enzymes, and terminology in bacterial metabolism are elaborated. The manuscript then examines acetic acid bacteria and lactic acid bacteria. Discussions focus on lactate, ethanol, glucose, and glycerol metabolism, glycol oxidation, homofermentation, polysaccharide formation, and electron transport systems. The publication takes a look at pseudomonadaceae and nitrogen metabolism as an energy source for anaerobic microorganisms. Topics include metabolism of pairs of amino acids, single amino acid metabolism, oxidation of glycolate and malonate, and oxygenases. The book is a dependable source of information for readers interested in bacterial metabolism.

This is the first book on microbial energetics at this level, presenting an integrated approach to all major aspects of the subject. It is a research level introduction to bacterial bioenergetics, aimed at postgraduates coming to the field and other researchers wishing to acquire specialist knowledge. Each chapter covers the basics of the relevant topic leading to more extensive discussion relating to specialist research interests. Energy transduction is fundamental to all biochemical/physiological processes and therefore of interest to many.
