摘要
研究了碳源、氮源和Mg2+对高产色素低桔霉素红曲霉M onascus sp.sjs-3产色素和桔霉素的影响,确定了液态发酵最优培养基为玉米淀粉50g/L,大豆3g/L,ZnSO·47H2O0.5g/L,CaCl20.1g/L,K2H PO45g/L,K H2PO45g/L,M nSO4·H2O0.3g/L,FeSO·47H2O0.01g/L,发酵192h时,菌体色素产量达到最高,胞内的红色价为173U/mL,未检出桔霉素。
To increase the yield of Monascus pigments and to decrease the citrinin content, we studied the liquid fermentation conditions of Monascus sp. sis-3. The optimal medium compositions were determined as： corn starch 50 g, soybean 3 g, ZnSO4 · 7H2O 0.5 g, CaCl2 0.1 g, K2HPO4 5 g, KH2PO4 5 g, MnSO4·H2O 0.3 g, FeSO4·7H2O 0.01 g. The pigment yield was found to be the highest after fermentation for 192 h; and the red value was 173 μ/ml with no citrinin detected.
