康宁木霉固态发酵中药渣制备蛋白饲料

Solid-state Fermentation of Herb Residues to Produce Protein Feedstuff by Trichoderma koningii

考察了营养源和其它条件对康宁木霉固态发酵中药渣的影响,采用正交实验优化了发酵条件,同时在单菌种发酵的基础上,对康宁木霉和产朊假丝酵母混合发酵进行了初步探索。研究结果表明,利用康宁木霉固态发酵中药渣生产蛋白饲料是可行的;在优化发酵条件下,即氮源添加量为30 mg硫酸铵/g干药渣、初始pH 4.0、固液比1∶2、发酵时间4 d,中药渣中真蛋白含量由11.12%提高至17.80%,粗纤维含量由29.14%降低至17.50%。

The effect of incubation conditions on the solid fermentation of herb residues by Trichoderma koningii is studied,and the optimal fermentation condition is determined by orthogonal test.On the basis of single strain fermentation,the co-fermentation by Trichoderma koningii and Candida utilis was also investigated.The results show that the solid-state fermentation of herb residues by Trichoderma koningii to produce protein feedstuff is feasible.The content of real protein increases from 11.12% to 17.80% while...
