PROCESS FOR EXTRACTION OF EXOPOLYSACCHARIDE AND CAROTENOIDS IN SINGLE FERMENTATION

摘要

The present disclosure provides a process for the extraction of exopolysaccharide (EPS) and carotenoids from a single microorganism and in a single fermentation. The EPS secreted into the growth medium can be extracted using a hydrophilic fluid medium and the cell-bound carotenoids can be isolated using a polar fluid medium. The EPS extracted exhibit emulsifying, cell proliferative, wound healing and cytotoxic activities. The carotenoids extracted exhibit anti-oxidant activity.
