Abstract: The present investigation deals with the time course study of three different of Saccharomyces
cerevisiae (GCB-K5, GCA-II and KR18) during invertase production by submerged fermentation.
GCA-II was found to be the best producer of invertase (8.35 U ml‾1, 48 h after inoculation) having
high production yield coefficients (i.e., Yp/s and Yp/x). The product is a high cost product. Thus the
use of optimized strain for invertase production is economically more feasible due to shorter
incubation period and optimal production.
