Abstract: The enzyme βfructofuranosidase attacks beta-D-fructofuranoside (raffinose, stachyose and sucrose) from the fructose end. Saccharomyces GCA-II was used for the production of βfructofuranosidase by submerged fermentation. The effect of sucrose concentration and incubation time was worked out for maximal enzyme production. Sucrose at the level of 30.0 g l^-1 in fermentation medium was found to exert an inducible effect on enzyme synthesis by Saccharomyces strain after 48 h of inoculation. Enzyme production increased from 107.42 U ml^-1 to 118.58 U ml^-1 after optimization of the cultural conditions. Specific product rate and specific growth rate were also determined for the production of βfructofuranosidase by Saccharomyces in shake flask.
