酵母菌直接利用纤维素初探

A PRELIMINARY STUDY ON DIRECT UTILIZATION OF CELLULOSE BY YEAST

本研究从多种酵母菌中筛选出一种能够在ＣＭＣ－Ｎａ培养基上生长的菌种（编号为ＳＲＢ－１），它可以利用麦秸粗纤维为碳源进行繁殖。接菌培养４８小时后，粗纤维利用率为１０．１８％，蛋白质含量提高了９．８８％。此菌种可供用于饲料发酵的进一步研究。

A yeast strain(N0.SRB-1)which could grow on CMC-Na medium was obtained byscreening a number of yeast strains,It was found that the strain could utilize crude fibre of wheatstraw as carbon source,After fourty eight hours of culture, the utilization ratio of crude fibreamounted to 10.8%and the protein content in the culture increased by 9. 88%。The yeast strainwill be used for further study on fermented feed.
