| The aim of this work was to study the effect of carbon and nitrogen sources in submerged fermentation, and the casein effect on solid-state fermentation on rennin production by Mucor miehei. Biomass peaks reached 6.7; 8.1 and 8 g/L and enzymatic production peaks of 1,066; 857 and 480 Soxhlet Units (S.U.) for glucose concentration of 18; 25 and 35 g/L respectively. Flasks with baffles showed biomass peaks of 6.7; 8.3 and 10 g/L and enzyme activity peaks of 648; 279 and 300 S.U. for the same glucose concentration. The values of 923 and 667 S.U. were obtained when corn steep liquor and Proflo (Cottonseed Nutrients from Traders ®) were used. In SSF system the enzymatic activities were 414, 264 and 167 S.U., when using HCl 0.2 N, 0.3 N and 0.4 N respectively.... |
