Industrial enzymes submerged fermentation

The volume of cellulase produced by submerged fermentation is much larger than that produced by soHd culture, which is primarily limited to baking and Asian detergent appHcations. Worldwide consumption of cellulase from submerged fermentation is roughly 23,000 tonnes annually. The sales volume of cellulase is around 125 milHon, which represents over 10% of all industrial enzyme sales. 

Most industrial enzymes are produced by micro-organisms via submerged fermentation. Most fermentations are aerobic. The production process of industrial enzymes can be divided into three steps fermentation, recovery, and formulation. 

Fermentation done in the presence of excess of free water is termed as submerged fermentation (SmF). It is the preferred technology for industrial enzyme production due to ease of handling at large-scale when compared to SSF. Large-scale fermenters.
