-According to the metabolic requirements of microbial growth, it can be divided into aerobic fermentation tanks and anaerobic fermentation tanks. Aerobic fermentation tanks require ventilation and agitation for the production of antibiotics, amino acids, and other substances; Anaerobic fermentation tanks do not require ventilation and are used for fermentation of alcohol, lactic acid, and other substances.
-According to equipment characteristics, it can be divided into mechanical stirring and ventilation fermenters and non mechanical stirring and ventilation fermenters. The former includes circulating and self-priming fermentation tanks; The latter includes gas lift and jet fermentation tanks.
