Optimization of Medium Components for the Production of Flavonoids and Soluble Protein with Phellinus igniarius in Liquid Culture

摘要

Through orthogonal test and comprehensive balance analysis method, the optimal medium composition was determined: 3% wheat bran, 12% corn silk, 0.5% yeast extract, 0.15% KH_2PO_4, 0.05% MgSO_4. The best inoculation amount was 3%. With the optimal formula. The confirmation experiment was that the content of flavonoids in fermentation broth was 1.551 mg/mL, and the soluble protein content was 0.691 mg/mL.
