Provindsia rettgeri L1 capable of efficiently degrading petroleum and application thereof

Abstract

The invention relates to a strain of Providencia rettgeri L1 capable of efficiently degrading petroleum and an application thereof. The strain is preserved in China General Microbiological Culture Collection Center (CGMCC) on September 26, 2018, an address is Institute of Microbiology, Chinese Academic Sciences, No.3, Yard 1, Beichen West Road, Chaoyang District, Beijing, and a strain preservationnumber is CGMCC No.16526. According to the invention, the strain of Providenia has a petroleum hydrocarbon degradation function, has differential selectivity on degradation of four components in petroleum, especially has a very remarkable degradation effect on n-alkanes of one of the petroleum components, can be applied to treatment of petroleum pollutants, and has a wide application prospect.

Description

technical field

[0001] The invention relates to a strain of Providencia rettgeri (Providencia rettgeri) L1 that efficiently degrades petroleum and its application, belonging to the technical field of petroleum degradation. Background technique

[0002] Since the end of the 1970s, with the acceleration of industrialization and the development of society, the production and consumption of oil have been increasing, which in turn has promoted the rapid development of the oil extraction industry and the petrochemical industry. In the process of mining, transportation and processing, oil pollution of the soil is caused by man-made or uncontrollable factors such as leakage, stacking and volatilization. According to relevant statistics, the world's current annual oil production reaches 2.2 billion tons, of which more than 8 million tons of crude oil enter the environment due to accidents and other reasons in the process of exploitation, transportation, processing and storage. As fa...
