Abstract

The invention relates to the field of biotechnology, in particular to a lysine bacillus ZCGT05 and its application. The present invention provides a bacterial strain with a preservation number of CGMCC NO.16935, and discloses the application of the bacterial strain to produce chitin deacetylase. The present invention also provides the screening and cultivation of the bacterial strain and the preparation of chitin deacetylase In the method, the bacterial strain is fermented and centrifuged, and the supernatant can be a chitin deacetylase solution. And after several experiments, the optimal fermentation condition for the strain to produce chitin deacetylase is provided.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a lysine bacillus ZCGT05 and its application. Background technique [0002] Chitin is a nitrogen-containing polysaccharide substance, also known as chitin, chitin, chitin, shell protein, etc. It is the second largest biopolymer in nature after cellulose. Chitin is widely distributed in nature. It is an important component of the shells of many lower animals, especially arthropods such as shrimp, crabs, and insects. It is also a component of the cell membranes of lower plant fungi, yeast, green algae, lichens, It is also contained in jellyfish and squid. The appearance of chitin is white or yellowish, it is a polymer of 2-acetylglucosamine, and its chemical structure is similar to natural cellulose. In addition to hydroxyl groups, chitin molecules also contain acetamido and amino functional groups. There are many groups available for structural modification, and it has more function...
