Microbiology for Sanitary Engineers (facultative anaerobic) grows under either aerobic or anaerobic conditions – – –

To live, grow and reproduce, a cell must be capable of performing a multitude of chemical changes. It may have to alter nutrients in the medium before they can enter the cell. It must make additional changes once the nutrients are in the cell. Some of the substances assimilated may be synthesized into compounds which become part of the cell.
