Technology for increasing nutrient value of cottonseed meal feed by microorganism fermentation method

Abstract

The invention discloses a technology for increasing the nutrient value of a cottonseed meal feed by a microorganism fermentation method. A modern bacterium mixing microorganism fermentation technique,an enzyme technique and the like are integrated, and a cottonseed meal protein feed which is high in protein, high in amino acid content, low in free gossypol content and high in feed return rate isresearched and developed. The specific technology comprises two working procedures of performing bacterium mixing aerobic fermentation and bacterium mixing anaerobic fermentation, wherein aerobic fermentation bacterium groups comprise aspergillus niger, microzymes, bacillus subtilis and bacillus psychrosaccharolyticus; and anaerobic fermentation bacterium groups comprise clostridium butyricum andlactic acid bacteria. According to the technology, multiple bacterium mixing fermentation is adopted, and through combination of different metabolic capabilities, the complex metabolism which is difficult to complete by single strains is completed; through the synergic fermentation among microorganisms, the important positive effect on effective transformation of various raw materials and increaseof the quality of the protein feed is achieved; and the technology has the advantages of being good in product efficacy, simple and efficient in technology, short in fermentation period, low in production cost and the like, and is easy in industrialized large-scale production.

Description

Technical field [0001] The invention relates to a process for improving the nutritional value of cotton meal by using a microbial fermentation method, in particular to a production process for preparing fermented cotton meal with high protein content and high feed rate by synergistic fermentation of multiple probiotics, belonging to the field of bioengineering . Background technique [0002] The shortage of feed resources, especially protein feed, is one of the bottlenecks restricting the development of my country's animal husbandry. How to effectively alleviate the shortage of protein feed resources in my country is a major issue to be solved. Protein raw materials are the foundation of the development of the feed industry. The shortage of protein raw materials and high prices in my country have become a bottleneck restricting the development of animal husbandry. At present, with the improvement of people’s living standards and the emphasis on quality of life, the demand for me...
