蝙蝠蛾拟青霉菌丝体发酵的研究

STUDY ON FERMENTATION OF MYCELIUM OF PAECILOMYCES HEPIALI

用20t发酵罐培养蝙蝠蛾拟青霉。菌粉收率达2．5％，D-甘露醇含量大于8％，腺苷含量大于0．2％．对发酵过程中pH、总糖、还原糖、得率、折光等的变化规律进行了考察．确定以发酵液pH的升高和还原糖含量作为综合判断发酵终点的依据．

Paecilomyces hepiali is cultured in a 20t fermentor. The yield of microbe powder is 2.5%.Content of D-mannitol is more than 8% and adenosine is more than 0.2%. The regular of pH total sugar, reducing sugar,yield and refractive index in the process of the fermentation are explored. The ascension of pH and the content of reducing sugar in fermentation liquid is defined as the basis for deciding the end of fermentation.
