Title (EN) METHOD FOR PRODUCING N-ACETYL-D-GLUCOSAMINE AND/OR D-GLUCOSAMINE SALT BY MICROBIAL FERMENTATION
(FR) PROCÉDÉ DE PRODUCTION DE N-ACÉTYL-D-GLUCOSAMINE ET/OU DE SEL DE D-GLUCOSAMINE PAR FERMENTATION MICROBIENNE
(ZH) 微生物发酵生产N-乙酰-D-氨基葡萄糖和/或D-氨基葡萄糖盐的方法
Abstract:
(EN) Provided is a method for producing N-acetyl-D-glucosamine and a D-glucosamine salt by means of microbial fermentation. The method, by increasing the effect of D-glucosamine-6-phosphate deaminase (NagB) in microbes while reducing the effect to glucosamine-6-phosphate synthase (GlmS), or by increasing the effect of GlmS in the microbes while reducing the effect of NagB, boots production of N-acetyl-D-glucosamine and/or the D-glucosamine salt.
(FR) L'invention concerne un procédé de production de N-acétyl-D-glucosamine et d'un sel de D-glucosamine par fermentation microbienne. Le procédé selon l'invention permet, en augmentant l'effet de la D-glucosamine-6-phosphate désaminase (NagB) dans des microbes tout en réduisant l'effet de la glucosamine-6-phosphate synthase (GlmS), ou en augmentant l'effet de la GlmS dans les microbes tout en réduisant l'effet de la NagB, de stimuler la production de N-acétyl-D-glucosamine et/ou du sel de D-glucosamine.
(ZH) 本发明提供了一种通过微生物发酵生产N-乙酰-D-氨基葡萄糖和D-氨基葡萄糖盐的方法。所述方法通过提高微生物中D-氨基葡萄糖-6-磷酸脱氨酶(NagB)的作用,同时降低氨基葡萄糖-6-磷酸合成酶(GlmS)的作用,或者提高微生物中GlmS的作用,同时降低NagB的作用,以加强N-乙酰-D-氨基葡萄糖和/或D-氨基葡萄糖盐的生产。
