Abstract
This invention provides a fermentation method of producing gellan gum, wherein a certain amount of fermentation broth is retained in the fermentor as a seed for next batch fermentation or transferred to another fermentor as a seed for next batch fermentation in that fermentor. The fermentation method of this invention reduces fermentation cost of gellan gum and lowers contamination risk during seed cultivation.
