| Abstract: | The optimal medium for raw starch enzyme producer-Rhizopus OR 1UVN was investigated. The optimal medium was established as follows(g/L):corn 50, soybean cake 30, NaNO 3 4,bran 10, MgSO 4·7H 2O 0.5, ZnSO 4 0 5, K 2HPO 4 1. The figures of fermentation process by Rhizopus OR 1UVN showed that the time of enzyme synthesis was from 40h to 48h and RDA (raw starch digesting ability) was 0.75. |
