摘　　要：采用厌氧混合微生物菌群处理香蕉秸秆,研究纤维素等难消化物质的降解率,并探讨了香蕉秸秆制取饲料原料的可行性。结果表明,采用厌氧混合微生物菌群可显著降解纤维素等难消化物质,从而提高香蕉秸秆中可溶性物质的含量。处理后,纤维素在香蕉秸秆中的含量下降了62.2%,而可溶性物质的含量提高了51.1%。但与前两种物质相比较,半纤维素在处理后降解率相对较低。同时,检测发现香蕉秸秆中的汞、镉、铅和铜的含量皆远低于饲料用重金属所允许量的国家标准或地方标准。Anaerobic mixed microbe flora was used for treatment of banana stalk, to study the degradation rate of indigestible substances such as cellulose etc. , and to discuss the feasibility of manufacture of feedstuff from ba- nana stalk. The result showed that the anaerobic mixed microbe flora could significantly degrade the indigestible substances such as cellulose etc. , to increase the content of soluble substances in banana stalk. After treatment, the content of cellulose in banana stalk was decreased by 62.2%, while the content of soluble substances was in- creased by 51.1%. But in comparison with first two substances, the degradation rate of semi-cellulose after treat- ment was relatively lower. At the same time, it was found that the contents of mercury, cadmium, lead and copper detected in banana stalk were far lower than the permissible contents of heavy metals in feeds in national or local standards.
