Abstract

The invention discloses Sphingobacterium sp. with an aniline degradation capability. The 16 SrDNA of the Sphingobacterium sp. is identified as Sphingobacterium sp., and is numbered BA-4; the Sphingobacterium sp. is collected in the China General Microbiological Culture Collection Center with the collection number CGMCC No.:13428; the Sphingobacterium sp. is a short rod, and belongs to a Gram-negative bacterium; a round faint yellow bacterial colony is formed on a beef extract-peptone solid culture medium, and is wet in surface, neat in edge and easy to pick. The invention further discloses an application of the Sphingobacterium sp. to aniline degradation. The Sphingobacterium sp. BA-4 is applied to degradation of aniline in a sewage system, has very high degradation rate and tolerance concentration, is free from secondary pollution, is safe to use, and has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of environmental microorganisms and waste water treatment, and in particular relates to a sphingobacterium capable of degrading aniline and an application thereof. Background technique [0002] It is reported that the production and usage of phenol and aniline account for more than 90% of the total amount of aromatics. Among them, aniline, one of the most important intermediates in the chemical industry, is widely used: in the dye industry, it can be used to make acid bright yellow and direct orange. S, direct pink, indigo, disperse yellow brown, cationic pink FG and reactive brilliant red X-SB and other dyes can also be used to manufacture organic pigments such as golden red, scarlet pink, phenol cyanine red and oil-soluble black; in the rubber manufacturing industry, it is An important raw material for rubber additives, which can be used to manufacture anti-aging agents, accelerators, antioxidants, stabilizers, etc....
