摘要
从不同的红曲样品中分离纯化获得红曲霉菌株 5株 ,以此为菌种液态发酵制备红曲 ,选出发酵后菌丝体色价与发酵原液色价都相对较高的编号为M3的菌株为出发菌株 ,进行了6 0 Co γ射线的诱变 ,获得了编号为M 3 2相对高产的色素菌株 ,其发酵后菌丝体总色价和发酵液总色价分别提高了 2 7 0 8%和 2 5 90 %。并对其液态发酵制备的红曲色素进行了质量分析。
In this paper, five strains of Monascus spp (M1～M5) were isolated and screened from Hongqu products. Then 5 Hongqu samples were prepared with the 5 strains by submerged fermentation. A strain of Monascus spp (M3) which products high Monascus pigment was choosen to be original strain. Through the mutagen of 60Co-γ,a mutant strain of Monascus spp (M3-2) from M3 was obtained which can produce much higher Monascus pigment than M3 could. The total color value of the fermentative mycelia and fermentation broth were increased by 27.08%, 25.90% respectively. The quality of Monascus pigment gained by the liquid fermentation of M3-2 was also studied.
