BREVIBACILLUS NITRIFICANS STRAIN YJ1 AND APPLICATION THEREOF

摘要

Provided are an n-hexadecane degrading bacterial strain YJ1 and an application thereof. The degrading bacterial strain with n-hexadecane as a carbon source is identified as Brevibacillus nitrificans on the basis of the bacterial strain morphology, physiological characteristics, Gram staining reaction, 16SrDNA gene sequencing analysis, and phylogenetic analysis, and is named YJ1. The bacterial strain was preserved in the General Microbiology Center of the China Microbial Culture Collection Management Committee in August 2019, and the preservation number is CGMCC NO.18418; the bacterial strain can use n-hexadecane as the sole carbon source and quickly degrade same: after culturing for 15 days in an environment with an initial concentration of n-hexadecane of 10 mg/L, the degradation rate can reach 66.7%. The optimal growth conditions for the bacterial strain are 30°C, pH=7, and inoculation amount 10%
