Document Type and Number:
WIPO Patent Application WO/2023/050513
Kind Code:
A1
Abstract:
Disclosed are a fungus LJD-6 capable of efficiently degrading benzo[a]pyrene and an application thereof. Aspergillus elsenburgensis LJD-6 was preserved in Guangdong Microbial Culture Collection Center (GDMCC) on August 31, 2021, with the address of 5th Floor, Building 59, Yard 100, Xianlie Middle Road, Guangzhou City, Guangdong Province, the postal code of 510070, and the preservation number of GDMCC No: 61887. A benzo[a]pyrene degradation bacterium LJD-6 that can grow with the benzo[a]pyrene as a carbon source is obtained by enriching and separating from Hangzhou petroleum-contaminated soil. The strain LJD-6 is an obligate aerobic bacterium, and can form a colony of 3-7 mm, which is brownish green and quasi-circular, has an irregular edge, and has gray fluffy hyphae growing upwards; and the back surface of the strain LJD-6 is yellow. LJD-6 is a strain capable of efficiently degrading the benzo[a]pyrene, has strong adaptability to polycyclic aromatic hydrocarbons, and also has good application potential in the aspect of bioremediation of benzo[a]pyrene.
