Abstract

The invention discloses a bacterial strain for degradation of p-xylene and a culture method and application thereof, the bacterial strain is named as Pandoraea sp WL1, the bacterial strain is preserved in the China General Microbiological Culture Collection Center(CGMCC), wherein the accession number is CGMCC NO.7897, and the accession date is July 8th, 2013. The bacterial strain for the degradation of the p-xylene is aerobic-type gram-negative bacteria, can grow by use of the p-xylene as a unique carbon source and energy, and can be completely mineralized into carbon dioxide and water; under the pure culture condition, the bacterial strain can degrade the p-xylene under the conditions of the temperature of 25-35 DEG C and the pH value of 4 to 8; the bacterial strain has good adaptive capacity to a substrate and the broadness to the substrate, can simultaneously degrade the p-xylene and methylbenzene. The bacterial strain lays a foundation for the industrial application of a biological method for disposing organic waste gases.

Description

technical field

[0001] The invention relates to the field of microbial strains, in particular to a strain for degrading p-xylene, a cultivation method and application thereof. Background technique

[0002] At present, the environmental problems and potential health problems caused by the low-concentration organic waste gas produced by the fine chemical industry are attracting increasing attention. Volatile organic compounds (VOCs) produced in the fine chemical industry have been regarded as a successor to dust due to their wide variety, wide distribution, high toxicity, wide pollution area, large gas volume, and low concentration. At the same time, the problems caused by pollution are complicated. The second largest category of air pollutants with a large amount and a wide range in the future. According to industry calculations, the current national total industrial VOCs annual emissions should be over 20 million tons, reaching or even exceeding the national NO x The level...
