Abstract

The invention relates to the technical field of microbial fermentation, specifically to a microbial starter for rice straw fermentation and a preparation method of the microbial starter for the rice straw fermentation. The starter is prepared from the following raw materials: corn stalks, tomato stalks, Pseudomonas stutzeri, Bacillus thuringiensis, Bacillus mucilaginosus, Phanerochaete chrysosporium Burdsall, Bacillus licheniformis, Trichoderma viride, Trichoderma koningii, Trichoderma reesei, Saccharomyces sp, cellulase, protease and phosphorylase. The microbial starter for the rice straw fermentation and the preparation method of the microbial starter for the rice straw fermentation disclosed by the invention can solve the technical problem of difficult degradation of rice straw, the microbial starter disclosed by the invention has a rapid temperature rise during use, thereby being beneficial to prolonging the high-temperature fermentation time and improving the degradation rate of cellulose and hemicellulose in the rice straw, and fermented final products are rich in nutritional components.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a microbial starter for rice straw fermentation and a preparation method thereof. Background technique [0002] Rice is one of the most widely planted crops in the world. After harvesting rice every year, a large amount of rice straw will be left. Except for some straws used in papermaking and energy industries, most of the other straws are processed in the form of incineration and stacking. Straws Incineration will not only waste organic carbon and other nutrient resources in straw, but also pollute the atmospheric environment; stacking of straw will take up space for a long time, and due to the high content of cellulose, hemicellulose and lignin in rice straw, Therefore it is difficult to form compost and return it to the field for use. It can be seen that it is of great significance to develop a microbial starter that can quickly and effectively degrade rice st...
