PPT-Bacterial Growth

By Dr Marwa Salah Learning objectives Definition of bacterial growth Requirements of bacterial growth Types of respiration in bacteria Phases of bacterial growth curve Growth involves an increase in the size and number of organisms. Conventional directcount assays of bacterial viability are based on metabolic characteristics or membrane integrity However methods relying on metabolic characteristics often only work for a limited subset of bacterial groups and methods for assessi Growth Characteristics.
