Abstract

The invention discloses a method for preparing a composite enzyme / probiotic preparation for feed by bioconverting pumpkin vine and leaf and olive cake pulp, which comprises the following steps: thoroughly mixing Pu'er tea after pile fermentation, shiitake stick, agrocybe aegerita stick, first pumpkin vine, first olive cake pulp, first wheat bran, first apple pomace and first water, and carrying out acclimatization culture to form a leavening agent; and thoroughly mixing the leavening agent, second pumpkin vine, second olive cake pulp, second wheat bran, second apple pomace and second water, and fermenting to obtain the composite enzyme / probiotic preparation for feed. In the invention, the microecologically-stable food-grade safe florae are utilized to ferment the pumpkin vine and olive cake pulp to prepare the composite enzyme / probiotic preparation for feed with favorable performance indexes, thereby implementing low-cost high-efficiency bioconversion of the pumpkin vine and olive cake pulp. Meanwhile, the method disclosed by the invention has the advantages of easy growth of microorganisms, high enzyme activity and extensive fermentation process, and can easily implement industrialized large-scale production.

Description

technical field [0001] The invention belongs to the field of microbial fermentation, and in particular relates to a method for fermenting pumpkin vines and olive 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...
