摘要
利用氨处理酸中和的方法对玉米秸秆进行预处理，再通过几种微生物绿色木霉ＴＢ１０１、假丝酵母（３２１、１８１７）、啤酒酵母２．３３９构成混合菌共发酵体系，依据多种微生物生长及代谢特性，利用正交实验法，优化出一套完整可行的混合菌发酵的技术路线和工艺方法，以实现玉米秸秆微生物的有效利用。在发酵温度为３０℃，培养基的最初ｐＨ５．０，木霉接种７２小时后接酵母，再发酵５天后测得蛋白质在绝干产物中的含量可达成２１％，纤维素的利用率７２％。这些为开发自然界这一重要秸秆资源奠定坚实的基础。
Maize stalk that on be rused is one of the biggest cellulose resources. Pretreatment methods were used on stalks by adding ammonia. Acid was added to control the pH at 5. 0 at the beginning of the quartered test. The results of the mixed fermentation showed that the suit technological routine and methods were very available by co - cultivation of Trichoderma TB101 and three Yeast utilizes (321. 1817.2. 339). The suitable fermentation conditions were based on these Microbus's living characters, including the fermentation temperature of 30℃ and inoculated yeast inoculums and 5 days lasted, these microbes could produce proteins on maize stalk, and protein content to 21 % in dry fermentation material, total cellulose used rate to 72%. The research will bring great effects in using maize stalk as an important natural resource.
