Gellan Gum Summary
The microbial exopolysaccharides are water-soluble polymers secreted by microorganisms during fermentation.
This article presents a critical review of the available information on the gellan gum synthesized by Sphingomonas paucimobilis with special emphasis on its fermentative production and downstream processing. Rheological behaviour of fermentation broth during fermentative production of gellan gum and problems associated with mass transfer have been addressed.
