| 摘 要： | 考察不同碳源、氮源及前体物质对菌株Streptomyce natalensis摇瓶发酵生产纳他霉素的影响。试验表明，纳他霉素摇瓶发酵培养基最佳碳源为葡萄糖、糊精，浓度分别为40g／L和32g／L；最佳氮源为酵母粉，浓度为4．5g／L；前体物质丙酸钠加入量为0．20％，最适加入时间为对数生长后期（48h）。

| Abstract: | The effects of carbon source, nitrogen source and precursor on natamycin production of Streptomyce natalensis in shake flask fermentation were studied.The results showed that 40g/L glucose or 32g/L dextrin was the optimum carbon source, and 4.5g/L yeast extract was the optimal nitrogen source during shake flask fermentation.The optimal addition time of the precusor, sodium propionate, was the later phase of logarithmic growth (48h) at a concentration of 0.20%. |
