Abstract

The invention discloses a method for producing glucosamine. The provided method for producing glucosamine comprises the following steps: N-acetyl-D-glucosamine as a raw material is used for producingglucosamine under the action of an engineering bacterium; the engineering bacterium is a recombinant bacterium expressing functional protein and is obtained by introducing a functional gene encoding the functional protein into a starting bacterium; the functional protein is N-acetyl-6-glucosamine phosphate deacetylase or chitobiose deacetylase. The method for preparing glucosamine has the advantages of mild reaction conditions, simple process route and high product purity, and is suitable for large-scale industrial production, and very suitable for popularization and application.

Description

technical field

[0001] The invention belongs to the field of genetic engineering, and in particular relates to a method for producing glucosamine. Background technique

[0002] Glucosamine, also known as Glucosamine (GlcN), referred to as ammonia sugar, widely exists in animal exoskeletons and microbial cell walls. Glucosamine is widely used in food, health care, cosmetics, medicine and other industries. Glucosamine is an important nutrient for the formation of cartilage tissue cells. It is a natural component of healthy articular cartilage tissue. It can help repair and maintain cartilage tissue and stimulate the growth and development of cartilage tissue cells.

[0003] At present, the production method of glucosamine is mainly chitin hydrolysis. The chitin hydrolysis method is the production of glucosamine from chitin in the shells of shrimps and crabs. This method has caused overfishing of marine resources, and the waste liquid produced by the processing and treatment ...
