[0029] Example

[0030] Domestication and isolation of crystal violet degrading bacteria

[0031] Take 3.0 g of soil sample contaminated by dye for a long time and place it in 100 mL of inorganic salt medium with initial crystal violet concentration of 5mg / L, and culture it with shaking at 30℃ and 130r / min; observe the decolorization of crystal violet every 2d. Take 5ml of the bacteria suspension with the best decolorization effect and transfer it to a fresh crystal violet culture solution, and gradually increase the mass concentration of crystal violet to 10, 20, 40, 60, 80, 100 mg / L, and carry out the domestication of the bacteria and determine the crystallization Violet degradation and decolorization effect; apply a suspension of domesticated bacteria that can decolorize 100 mg / L crystal violet solution on a solid dye plate containing 30 mg / L crystal violet to isolate crystal violet degrading bacteria and perform strain identification, namely Get crystal violet degrading bacter...

Abstract

The invention provides a crystal violet degrading bacterium. The crystal violet degrading bacterium is Cedeceadavisae and is used for crystal violet dye decolorization and degradation. A preparation method of the crystal violet degrading bacterium is simple and stable and has good operability. The Cedeceadavisae strain can fast decolorize and degrade a crystal violet dye and purify water, is saferthan a chemical method and has no secondary pollution.

Description

technical field [0001] The invention relates to the field of dye-degrading bacteria, in particular to a crystal violet-degrading bacteria. Background technique [0002] With the rapid development of the printing and dyeing industry, the pollution of dye wastewater is becoming more and more serious. It has the characteristics of high alkalinity, high organic content, and even heavy metals, which has become one of the most difficult environmental pollution problems to deal with. [0003] Crystal violet dyes are the third most widely used dyes after azo dyes and anthraquinone dyes. Its discharge will definitely cause serious pollution of water body and soil, and cause great harm to human health. Research on the degradation of wastewater containing crystal violet is of great significance to the degradation of dye wastewater. [0004] Cedricella is rod-shaped cells, 0.5 ~ 0.6μm × 1 ~ 2μm, in line with the definition of the general genus Enterobacter. Most strains are sporty. ...
