These studies were conducted to investigate the cultural characteristics of Streptomyces griseolus isolated from the soil. The addition of sweet potato starch also proved effective in promoting the total enzyme activity measured at 29% higher than the control. By the addition of both 2% of xylose syrup (Be'28) prepared with 655 of corn steep liquor (total nitrogen 1.2%), enzyme induction was maximized. The enzyme activity was stimulated by the xylose and the cell growth by the C.S.L.. OOz of the biomass cultured in 30l capacity jarfermentor recorded low oxygen requirement of 251.2l/hr. Conversion ratio of 60% glucose to fructose was 42.5% after 70 hrs. reaction
