双菌共固定化耦合催化发酵生产红色染色剂的研究

Study on red coloring agent production by fermentation of coincidence with double microorganisms with immobilized cell

根据微生物的协同作用理论,采用酿酒酵母与红曲双菌共固定化耦合发酵生产红曲色素。实验结果表明:红曲霉菌与酿酒酵母菌体量配比为4:1时,固定化细胞双菌耦合发酵产红曲色素是红曲霉菌单菌固定化发酵产色素量的约1.6倍。

According to the synergistic effect of the microorganisms, the cells of Saccharomyces cerevisiae and the cells of Monascus purpurs were co-immobilized for monascus pigment fermentation. The experimental results showed that when the Monascus purpurs to Saccharomyces cerevisiae ratio was 4：1, the yield of monascus pigment produced by co-immobilized with double microorganisms increased about 60% higher than that of fermentation with the single microorganism immobilized of Monascus purpurs.
