Streptomyces sp. FIM-16-06产他克莫司摇瓶发酵条件的优化
Optimization of fermentation conditions of tacrolimus-producing strain Streptomyces sp. FIM-16-06
摘要
Abstract
In order to optimize the fermentation conditions for tacrolimus-producing strain Streptomyces sp. FIM-16-06, the single factor experiments and orthogonal experiments were adopted to investigate the liquid fermentation medium and culturing parameters of Streptomyces sp. FIM-16-06. The results revealed that the appropriate fermentation medium composition and optimal fermentation parameters were determined as follows: fermentation medium containing corn starch6.0%, glucose 2.0%, soybean flour 2.0% and corn steep liquor 0.5%, while the initial pH 7.5, filling volume 50 m L/500 m L shake flask, cultivation time of seed 48 h, inoculum size 10%, shaker''s rotating speed 250 r/min, fermentation temperature 27 ℃ and fermentation time 7 d. The tacrolimus yield of Streptomyces sp. FIM-16-06 under the optimized fermentation conditions was 60% higher than that of the original. The optimal fermentation conditions of Streptomyces sp.FIM-16-06 laid the foundation for further industrial fermentation.关键词
