摘　　要：对红曲霉固态发酵产红曲色素的条件进行了探索,通过单因素试验和正交试验确定了利用红曲霉固态发酵生产红曲色素的最佳培养基为:培养基初始含水量为50%、3%葡萄糖、0.1%甘油、3%酵母粉、0.1%硝酸铵、0.2%氯化铵、2%蛋白胨、0.4%硫酸镁、0.3%磷酸二氢钾。发酵所得红曲色素的色价可达到1302U/g。In this paper, the fermentation condition of monascus pigment by solid-state fermentation of Monascus was studied. An optimum medium was obtained through single factor experiments and orthogonal experiment. That is, the initial water content 50%, 3% glucose, 0.1% glycerol, 3%yeast powder, 0.1% NH4NO4, 0.2% NH4Cl, 2% peptone, 0.4% MgSO4, 0.3% KH2PO4. Under this condition, the color scale of monascus pigment can reach 1302 U/g.
