摘要
对同化淀粉、纤维二糖及 Ｄ木糖能力强的糖化酵母菌 Ｙ９６０１ 株在井冈霉素废渣固态发酵法生产饲料蛋白中的应用进行了工艺条件的优化研究。试验结果表明，发酵产物酵母数达到４８ ～４９ ×１０９ 个／ｇ ，粗蛋白从３２１ ％ 提高到４５６ ％ ，真蛋白从原来的２９８ ％ 提高到３９３０ ％ ，真蛋白实际提高量４７３ ％ ，氨基酸总量３６５６ ％ 。
The optimization process conditions for the application of saccharomyces diastaticus Y9601 with stronger ability to assimilate starch, cellobiose and D-xylose in the production of feed protein from the residue of Jinggangmeisu through solid-state fermentation were studied. The results showed that the number of the yeasts in the fermented products reached up 4.8～4.9×10 9 per gram, the contens of crude protein increased to 45.6% from 32.1%, and the real protein increased to 39.30% from 29.38%. The concentration of real protein increased by 4.73% and the total contents of amino acid were 36.56%.
