Bacterial physiology and genetics can be summarized as follows: 1. Bacterial physiology refers to the biochemical reactions that enable bacteria to live, grow and reproduce. Important factors for bacterial growth include nutrients, temperature, pH, and oxygen requirements. 2. Bacteria grow through a lag phase, log phase, stationary phase, and death phase. The log phase is when rapid, exponential growth occurs through binary fission. 3. Bacterial genetics involves the study of heredity and variation in bacteria. Genetic information is contained in bacterial chromosomes and plasmids, and can be transferred between bacteria through transformation, transduction, and conjugation.
