Although lysine can also be extracted from the hydrolysate of protein raw materials (such as pig blood powder), the lysine used is mainly produced by fermentationLysine hydrochlorideL-lysine is obtained by extraction method and fermentation method.In fermentationDiaminoheptanedioic acidThe two-step method and the one-step method using sugar as raw material are more widely used in sugar fermentation.Diaminoheptanedioic acid production process: using Escher'sEscherichia coli(Escherichia Coli) Biosynthesis of L-lysine is a mutant strain of Escherichia coli that can not grow without lysine without the function of diaminoheptanedicarboxylase. Glycerin, corn steep solution, ammonium phosphate, etc. are used as the culture medium for culture. A large amount of diaminoheptanedicarboxylate will accumulate in the culture medium. At this time, the culture medium should be neutral,This is an important factor in improving efficiency.Then, the product with decarboxylation function for diaminoheptanedioic acid but no decarboxylation function for lysineAerobacter(Aerobator aerogenes) or common Escherichia coli body, after the decarboxylase is dissolved out with toluene, this enzyme can react with the aforementioned diaminoheptanedioic acid to almost quantitatively generate L-lysine, and thenion exchange resinThe finished product L-lysine hydrochloride is obtained by separation and refining.In the synthesis method, caprolactam is used as the starting material or dihydrofuran is used as the starting material. The racemate obtained by the synthesis method must be optically resolved.[1]
