    Description / Table of Contents: Bacterial Physiology focuses on the physiology and chemistry of microorganisms and the value of bacterial physiology in the other fields of biology. The selection first underscores the chemistry and structure of bacterial cells, including the chemical composition of cells, direct and indirect methods of cytology, vegetative multiplication, spores of bacteria, and cell structure. The text then elaborates on inheritance, variation, and adaptation and growth of bacteria. The publication reviews the physical and chemical factors affecting growth and death. Topics include hydrogen ion concentration and osmotic pressure; surface and other forces determining the distribution of bacteria in their environment; dynamics of disinfection and bacteriostasis; bacterial resistance; and types of antibacterial agents. The text also ponders on the anaerobic dissimilation of carbohydrates, bacterial oxidations, and autotrophic assimilation of carbon dioxide. The selection is a dependable reference for readers interested in bacterial physiology.
