Optimization of Fermentation Technology for Producing Single Cell Protein from Yam Starch by Orthogonal Test

摘要

Using Yam starch as raw material, the fermentation technology of Single Cell Protein (SCP) was optimized through by active dry yeast fermentation through single factor and orthogonal test in this study. The optimal conditions were showed as followed: 30 mL the medium volume in 250 mL flask, inoculum size17%, fermentation time 69 h, pH 5.0. Under these conditions, the production of SCP reached 241.54±0.15 (g wet weight/100 g Dry starch.
