天蓝色链霉菌产蓝色素的摇瓶发酵优化

The Optimization of the Blue Pigment Fermentation by Streptomyces coelicolor

对天蓝色链霉菌 -1 0 0产蓝色素进行了摇瓶条件优化 ,初步确定了促使蓝色素产率提高的合适培养基组成及培养条件 ,经过 8d发酵后 ,蓝色素总色价相对单位可达 1 49.2U/ml,比未优化前的总色价相对单位 1 0 9.2 U/ml提高了 3 7%。

The composition of fermentation medium and cultural conditions for Streptomyces coelicolor 100 producing blue pigment were studied and optimized. After 8 days' fermentation, the total blue pigment relatively value of 149.2 U/ml was obtained. It is increased by about 37% compared with that of orginal conditions.
