Although lysine can also be extracted from the hydrolysate of protein raw materials (such as pig blood meal), the lysine used is mainly lysine hydrochloride produced by fermentation, and both extraction and fermentation methods are L- Lysine. Among the fermentation methods, there are a two-step method through diaminopimelic acid and a one-step method using sugar as a raw material, and sugar fermentation is more used. Diaminopimelic acid production process: using Escherichia Escherichia coli to biosynthesize L-lysine, which is a kind of Escherichia coli that does not have the function of diaminopimelate decarboxylase and cannot grow without lysine. Strains, use glycerin, corn steeping liquid, ammonium phosphate, etc. as a medium for culture. A large amount of diaminopimelic acid will accumulate in the medium. At this time, the culture medium must be neutral, which is an important factor to improve efficiency. Then use aerobic bacillus or ordinary E. coli body that has the decarboxylation function for diaminopimelic acid but not lysine, and after the decarboxylase is dissolved with toluene, this enzyme and the aforementioned diamino The action of pimelic acid can produce L-lysine almost quantitatively, which is separated and refined by ion exchange resin to obtain the finished product L-lysine hydrochloride. In the synthesis method, there are methods using caprolactam as the starting material or dihydrofuran as the starting material. The synthesis method obtains racemates, which must be optically resolved.
1. Lysine is one of the most important amino acids, and the amino acid industry has become an industry of considerable scale and importance. Lysine is mainly used in food, medicine and feed.
2. It is used as a feed nutrient fortifier and is an essential component of livestock and poultry nutrition. It has the functions of enhancing the appetite of livestock and poultry, improving disease resistance, promoting the healing of trauma, and improving the quality of meat. It can enhance the secretion of gastric juice. It is an essential substance for the synthesis of brain nerves, germ cells, protein and hemoglobin.
