生物技术在粮油饲料资源增值转化中的应用研究进展

Research Progress on the Application of Biotechnology in Value-added Conversion of Grain,Oil and Feed Resources

优质蛋白饲料资源短缺成为影响我国粮食安全的重要变量。我国粮油加工副产物资源丰富,但是饲用价值偏低,通过生物发酵、酶解、合成生物学等现代生物技术对这些资源进行加工处理,能实现资源提质增效,达到替代大豆粕的目的。本文重点综述了发酵饲料、酶解饲料和菌体蛋白饲料的生产工艺、饲用价值以及在豆粕减量替代研究中的应用效果,同时介绍了微生物吸附、降解以及生物酶在脱除真菌毒素上的研究进展,最后对生物发酵饲料的开发、产业化应用、标准制定、行业监管等方面提出了研究展望。本文可为生物技术在粮油饲料资源增值上的应用提供有力指导。

The shortage of high-quality protein feed resources has become an important variable affecting food security in China.Grain and oil processing by-products are abundant in China,but the feeding value is low.If these resources are processed through modern biotechnology,such as biofermentation,enzymolysis technology or synthetic biology,their quality and efficiency will be improved and can be used to replace the soybean meal.This paper summarized the production process,feed value and its application in soybean meal replacement of fermented feed,enzymolysis feed and microbial protein feed,and also introduced the research progress of microbial adsorption,degradation,or enzymes on removing mycotoxins,finally put forward the research prospect of development,industrialization application,standard establishment,and industry supervision for biological fermentation feed.This paper can provide guidance for the application of biotechnology in grain and oil feed resources.
