Embodiment Construction

[0024] The present invention will be described in more detail below with reference to the examples and the drawings, but the embodiments of the present invention are not limited thereto.

[0025] 1. Embodiment:

[0026] In the present invention, the intestinal bacilli ENTEROBACTER CLOACAE GDUTAN7 having a benzene-degradation capability is a sore, purified from a garbage liquid in Guangzhou, Guangdong Province, in Guangdong Province, in Guangdong Province . Formulation in inorganic salt medium (K 2 HPO 4 · 3h 2 O 1.2g / l, kh 2 PO 4 1.2g / l, NH 4 CL 0.4g / L, MGSO 4 · 7h 2 O 0.2g / L, FESO 4 · 7h 2 O 0.01g / L, trace element: CaCL 2 · 2h 2 O 0.2g / L, MNSO 4 · 4h 2 O0.2g / L, CUSO 4 · 2h 2 O 0.01g / L, ZNSO 4 · 7h 2 O 0.2g / L, COCL 2 · 6h 2 O 0.09g / L, NA 2 MOO 4 · 2h 2 O0.12G / L, H 3 BO 3 0.006 g / L) Add a certain amount of benzene-based screening, and the concentration of domesticated substrate is 1 mg / L, 5 mg / L, 10 mg / L, 15 mg / L, 20 mg / L. First, 10 ml of waste lea...

Abstract

The invention discloses enterobacter cloacae with capability of degrading a benzene series and application of the enterobacter cloacae in environmental restoration. According to the enterobacter cloacae and the application thereof, the enterobacter cloacae with good capability of degrading the benzene series is screened and separated from landfill leachate of a certain refuse landfill in Guangzhou, Guangdong; and the enterobacter cloacae GDUTAN7 is preserved in the China Center for Type Culture Collection (CCTCC) on January 18, 2021, the address is Wuhan University, Wuhan, China, and the preservation number is CCTCC NO: M 2021091. The enterobacter cloacae GDUTAN7 disclosed by the invention has a relatively good degradation effect on the benzene series in environments and can be applied to the degradation of the benzene series in the environments, and thus, the aim of restoring the environments is achieved.

Description

Technical field [0001] The present invention belongs to the field of microbial technology, and more particularly to a galle coli with degradation capability and its application in environmental repair and VOCS purification. Background technique [0002] Benzene contamination mainly exists in the production and processing industry of crude oil and petroleum products, in the process of processing and transportation of these products, and in the process of leakage, with precipitation and floor water, water, etc., contaminated soil and Water body. At the same time, in industries such as paint production, plastic production, printing and dyeing and textile processing also produce wastewater and exhaust gases of high concentrations of benzene products. Since the benzene is strong in cancer, teratogenic and caused mutation, it is difficult to despise, and the migration ability has strongly visually attaches high attention, and is listed as prioritizing pollutants. Short-term high-dose e...
