Estimating the term…
The invention belongs to the field of cosmetic biotechnology, and specifically relates to an Enterobacter that degrades hyaluronic acid and a cultivation method and application thereof. The Enterobacter sp. CGJ001 of the present invention was deposited in the China General Microbiological Culture Collection Center on Oct. 10, 2019, and the preservation number is CGMCC NO. 18661. The Enterobacter strain can efficiently produce hyaluronidase, and can be used in the process of preparing low molecular hyaluronic acid and oligomeric hyaluronic acid from high molecular hyaluronic acid. The enzyme has high specificity towards hyaluronic acid, excellent thermal stability and pH stability, and is suitable for large-scale industrial application. Thus, it can replace the traditional hyaluronidase extracted from expensive animal tissues. There should be broad application prospects in the fields of medicine and cosmetics.
A method of producing hyaluronidase comprising subjecting an isolated strain of Enterobacter CGJ001 deposited at China General Microbiological Culture Collection Center with Accession Number CGMCC NO. 18661 to plate culture, seed culture, and fermentation culture.
