Opis

This concise yet comprehensive text surveys the field of bacterial metabolism in terms useful to students and researchers. Emphasis is on those metabolic reactions occurring only in bacteria. Thus, the book describes in detail the energy metabolism of the various groups of bacteria. In addition, it examines pathways used by bacteria for the degradation of organic compounds, the synthesis of cellular constituents, the regulation of bacterial metabolism and the fixation of molecular nitrogen.
