Rhodococcus ruber and application thereof in degradation of hydrocarbon compounds

Abstract

The invention relates to a bacterial strain of Rhodococcus ruber P14 CGMCC NO.2343. The bacterial strain has the characteristic of floating up from oil matters; the bacterial strain can grow by taking the oil matters as unique carbon source and energy source and degrade the oil matters; and the bacterial strain can grow by taking polycyclic aromatic hydrocarbon as unique carbon source and energy source and degrade hydrocarbon compounds, such as phenanthrene, pyrene, benzopyrene, and the like. The bacterial strain can degrade the oil matters and hydrocarbon compounds, especially the polycyclicaromatic hydrocarbon can be applied in the biological treatment of oily waste water and the biological repair (biological remediation) of oil-contaminated soil.

Description

technical field

[0001] The invention belongs to the field of microbial biotechnology and environmental biotechnology, and specifically relates to a strain of Rhodococcus sp., whose preservation number is: CGMCC NO.2343. Degrades oily substances containing hydrocarbons. Background technique

[0002] With the development of the economy, the human demand for energy is also expanding. All countries have accelerated the development and utilization of oil and gas resources. From deserts to oceans, from uninhabited areas to densely populated areas, more and more oil and gas wells appear all over the world. . Petroleum is a complex mixture composed of thousands of substances with different chemical properties, mainly including saturated hydrocarbons, aromatic hydrocarbons, asphaltenes, resins, etc. A series of oil pollution problems are caused by pollution and omission accidents in the process of oil extraction, smelting, use, and transportation, as well as the discharge of oily w...
