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.

Fermentation method for producing gellan gum

The invention relates to an optimized seed train expansion process.

Seed train for large scale enzyme production

The invention provides a new fermentation process for producing gellan gum, which can control the feeding amount and feeding speed of the nitrogen sources accurately and quantitatively, and control the growth and gum production of the strains, so as to significantly improve the controllability, stability and yield of the fermentation process for producing gellan gum.
