红曲霉液态发酵生产红色素的培养基配方优选

Study on the Submerged Fermentation Culture Medium Producing Red Pigment by Monascus

研究了菌株紫红曲霉No.1-18-54液态发酵生产红色素的培养基配方,通过对比实验和正交实验,得其最佳液体培养基配方为:大米粉9%,硝酸钠0.2%,磷酸二氢钾0.1%,硫酸镁0.2%.

The study was made to determine the optimal submerged fermentation culture medium for the yield of red pigment. Through comparing and orthogonal experiments, the best culture medium was the following： rice powder 9 %, NANO3 0.2 %, sodium glutamate 0.2, KH2 PO4 0.1%, MgSO4 0.2 %.
