纤维素水解液发酵生产氨基酸的研究进展

生物质是地球上最丰富的可再生资源，随着人类社会的快速发展，能源及资源危机日益凸现，开发和利用可再生资源已成为世界各国关注的热点，开展农业生物质资源转化研究也成为我国资源利用的重大基础和战略问题。中国是氨基酸的生产和消费大国，年总产量超过500万t。目前氨基酸发酵常采用玉米淀粉水解液作为碳源，拓展原料来源，寻找代替原料降低碳源成本，对氨基酸的成本构成决定性作用。该文主要介绍了我国生物质资源的现状，氨基酸的生产方法，重点论述了以纤维水解液生产氨基酸的研究进展及存在问题，为木质纤维素合理利用及氨基酸发展提供新的思路。

Research progress of amino acid production by cellulose hydrolysate

Biomass is the most abundant renewable resource on the planet. With the rapid development of the human society and emergence of energy and resource crises, the development and utilization of the renewable resources has gradually become a hot spot in the world, and the research on the transformation of agricultural biomass resources has become an important basis and strategic issue of resource utilization in China. China has become a major producer and consumer of amino acids with a total annual output of more than 5 million tons. At present, the fermentation production of amino acids usually uses corn starch hydrolysate as carbon source. Therefore, expanding the source of raw materials and searching alternative raw materials to reduce the cost of carbon sources, has a decisive effect on the cost of amino acids. In this paper, the current status of our country's biomass resources and the production methods were mainly introduced, and the research progress and existing problems of amino acid production from cellulose hydrolysate were emphatically discussed, which provided a new idea for the rational utilization of lignocellulose and the development of amino acids.
