specific Embodiment approach 1

[0018] Specific embodiment 1: The Bacillus cereus that can degrade phenol in this embodiment is Bacillus cereus (Bacillus cereus) WL027, which is preserved in the China Center for Type Culture Collection (CCTCC), and the preservation address is Wuhan University, Wuhan, and the preservation date is 2015 On July 10, 2015, the deposit number is CCTCCNo: M2015439.

[0019] In this embodiment, Bacillus cereus WL027 is Gram-positive, rod-shaped, with a cell size of (1.0 μm-1.2 μm)×(3.0 μm-5.0 μm), spore-producing, flagella, and movable. It can grow on MYP medium, the diameter of the colony is 8-10 mm, the texture is soft, and it is filamentous. After 48 hours of cultivation, the surface of the colony is ground glass and produces red pigment.

[0020] In this embodiment, the contact enzyme test of Bacillus cereus WL027 was positive, the oxidase test was positive, and the starch hydrolysis test was positive.

[0021] In this embodiment, Bacillus cereus WL027 can use ammonium chloride...

Abstract

The invention discloses bacillus cereus capable of degrading phenol and having an electrogenesis characteristic and application thereof and relates to bacillus cereus and application thereof. The bacillus cereus can degrade phenol and has the electrogenesis characteristic, and a foundation is laid for microorganism-utilized phenol treatment. The bacillus cereus capable of degrading the phenol is bacillus cereus WL027 and is preserved at the China Center for Type Culture Collection on July 10, 2015, and the preservation number is CCTCC No. M 2015439. The bacillus cereus WL027 can degrade phenol, has the electrogenesis characteristic, has good penicillin, chloramphenicol and tetracycline tolerance, has salt tolerance and can use aniline as a substrate. The bacillus cereus can be applied to microbial fuel cells.

Description

technical field [0001] The invention relates to a strain of bacillus cereus and its application. Background technique [0002] Phenol is a kind of aromatic compound, and it is a raw material and intermediate for the production of dyestuffs, papermaking, pesticides, pharmaceuticals and other industries. With the rapid development of my country's industry, the demand for phenol is increasing. At the same time, the discharge of phenol-containing wastewater is also increasing, and the pollution to the environment is becoming more and more serious. Phenol is a protoplasmic substance, which is toxic to all living organisms and has "three effects". Untreated phenol wastewater not only pollutes the environment, but also coagulates proteins, thereby endangering human health. [0003] At present, the treatment methods of phenolic wastewater include physical treatment methods (adsorption method, solvent extraction method and liquid membrane method), chemical treatment methods (oxidat...
