Abstract

The invention discloses a method for preparing a compound enzyme and probiotic preparation for feed through the biotransformation of corn stalks and soybean meals. The method comprises the following steps of: thoroughly mixing cooked Pu'er tea, first corn stalks, first soybean meals, first wheat bran, first apple pomace and first water which are subjected to pile fermentation, and carrying out acclimation culture so as to form a leavening agent; and thoroughly mixing the leavening agent, second corn stalks, second soybean meals, second wheat bran, second apple pomace and second water, and carrying out fermentation, thereby obtaining the compound enzyme and probiotic preparation for feed. According to the method, the compound enzyme and probiotic preparation with better various performance indexes is prepared through fermenting the corn stalks and the soybean meals by using food-grade safe flora with stable microbial states, so that the low-cost and high-efficiency biotransformation of the corn stalks and the soybean meals is realized. Meanwhile, the method disclosed by the invention has the advantages that microbes grow easily, the enzyme activity is high, the fermentation process is extensive, strict aseptic conditions are not required, and the industrial large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of microbial fermentation, and in particular relates to a method for fermenting corn stalks and soybean cakes with micro-ecologically stable food-grade safe flora to prepare a compound enzyme and probiotic preparation for feed. Background technique [0002] my country is a populous country with extremely tight arable land, and there is a huge gap in the demand for feed raw materials, especially energy feed and protein feed. [0003] Lignocellulose is the most abundant and cheapest renewable resource on earth. The production and processing of agricultural products and food also produces a large amount of lignocellulosic by-products. There are many kinds of lignocellulose, such as various crop straws, urban cellulosic waste, agricultural product processing by-products such as corncobs, vegetable stems and leaves, fruit and vegetable residues, etc. The components of lignocellulose mainly include cellulose, hemicellulose...
