Abstract

The invention belongs to the field of microbial biotechnology, and relates to a strain of Penicillium dermatophilum (P. crustosum) Pc-46 for producing Lovastatin by liquid fermentation. Specifically,the invention discloses a Pc-46 Penicillium crustosum Pc-46 (deposit No.: CCTCC NO: M 2018343), and also discloses an application of the Penicillium dermatophilum use and fermentation production method. Specifically, the present invention discloses Penicillium dermatophilum (P. crustosum)Pc-46 for preparing lovastatin; and the yield of Lovastatin is about 155mg/L to 158mg/L.

Description

technical field [0001] The invention belongs to the field of microbial biotechnology, and relates to a P.crustosum Pc-46 strain for producing Lovastatin by liquid fermentation, a use and a fermentation production method. Background technique [0002] Penicillium fungi are important industrial microbial resources in my country, widely distributed in soil, vegetation, air, food and other habitats. In 1928, Fleming in the United Kingdom discovered penicillin from Penicillium, which completely changed the medical treatment of bacterial diseases and brought Penicillium fungi into people's field of vision. In 1976, Professor Akira Endo, a Japanese scholar, discovered the first statin in the fermentation product of Penicillium penicillium. Lovastatin (Lovastatin) is recognized as an ideal drug for lowering cholesterol in various countries. It has the characteristics of high efficiency, low toxicity and safety. It can selectively inhibit the activity of hydroxymethylglutaric acid c...
