A kind of clean production process of L-glutamine fermentation method

Abstract

The invention belongs to the technical field of separation and extraction of amino acid and discloses a clean production process of L-glutamine by adopting a fermentation method. The clean production process comprises the steps of filtering, flocculating, performing isoelectric operation, concentrating, performing ultrafiltration, drying and the like, and finally, an L-glutamine product is obtained. The clean production process disclosed by the invention is operated according to the steps, so that the yield and the purity of the L-glutamine product are improved, the problem about environment caused by fermented industrial wastewater and waste residues is effectively solved, clean production of the L-glutamine by adopting the fermentation method is realized, and two purposes by one process are achieved.

Description

technical field [0001] The invention belongs to the technical field of separation and extraction of amino acids, and in particular relates to a clean production process of L-glutamine fermentation method. Background technique [0002] L-glutamine is the most common and indispensable conditional essential amino acid in the human body, accounting for 61% of the free amino acids in the human body. Originally found in beet juice, sprouted seeds and protein. L-glutamine plays a very important role in life activities. It is an amino acid that constitutes protein and an important biochemical reagent. It is mainly used clinically to treat diseases such as alcoholism, depression, and peptic ulcer, and has broad prospects for drug development. [0003] Affected by the characteristics of the industry, fermented products need to consume more water, electricity, steam, etc. in the production process. Waste water and waste residues in the fermentation industry are rich in protein, amino...

Problems solved by technology

Although good results have been achieved, these methods have many disadvantages, such as large investment, long processing cycle, peculiar smell, and unstable processing results.

Moreover, the L-glutamine production process also has defects such as cumbersome steps, high consumables, and low product yield and purity, which need further improvement
