目的]探讨雪白弯颈霉(Tolypocladium inflatum)产环孢菌素的最适发酵条件。方法]采用正交试验,研究不同培养时间、培养基种类、装瓶量、菌种接种量(以菌片计)对雪白弯颈霉产环孢菌素的影响。结果]在培养时间为4 d,发酵培养基为马铃薯200.00 g、甘露醇40.00 g、蛋白胨6.00 g,装瓶量为100 m L,菌片投放为9片时雪白弯颈霉产环孢菌素的发酵条件为最优。结论]试验结果为提高雪白弯颈霉产环孢菌的产量提供了理论依据。

Optimization of Fermentation Conditions for Production of Cyclosporin from Tolypocladium inflatum

Objective] To discuss the optimum fermentation conditions for the production of cyclosporin from Tolypocladium inflatum. Meth-od] Through an orthogonal experiment, the effects of culture time, culture medium, bottling capacity, and inoculation amount ( in slice) of T.inflatum on the production of cyclosporin were analyzed. Result] The optimum fermentation conditions for the production of cyclosporin from T.inflatum were shown as follows:the culture time was 4 d;the fermentation culture medium was composed of potato 200.00 g, manni-tol 40.00 g, and peptone 6.00 g;bottling capacity was 100 mL;inoculation amount was 9 slices. Conclusion] The study can provide theo-retical foundation for the improvement of yield of cyclosporin produced from T.inflatum.
