农作物秸秆发酵剂研究初报

Primary study on zymosis agent of fodder

通过对纤维素酶、半纤维素酶活力的比较,筛选出康宁木霉Km—1,米曲酶Mq—1作为纤维素分解酶菌种,再配合以热带假丝酵母菌Rj—1,白地酶菌Ba—1和植物乳酸菌ZH—1等,经分别培养后,按一定比例配成农作物秸秆发酵剂,秸秆发酵实验表明,在28℃条件下发酵96h,可使玉米秸秆、稻草粗蛋白含量分别提高2.95倍和2.29倍,粗纤维分别降低32.36%和17.39%,中性洗涤纤维(NDF)分别降低12.00%和11.00%,酸性洗涤纤维(ADF)分别降低14.60%和18.80%,且此发酵剂还具有酒香味、质地柔软、适口性好等优点.

Trichoolorima koningill(Km-1) and aspergillus(Mq-1) were chosen as germ species of cellulase by comparing the enzyme activity of cellulase and hemicellulase produced.After being germicultured,the zymosis agent of fodder was produced by adding Candida tropicalis,Geotrichum candidum and Lactobacillus plantarm.The results showed that in the corn fodder,the gross protein content enhanced as much as 2.95(Km-1) and 2.29(Mq-1) times;in the same order, raw fibre decreased 32.36% and 17.39%, NDF did 12% and 11% , ADF did 14.60% and 18.80% after being fermented 96?h at 28?℃.The fodder is soft, tasteful and odor.
