Application of sinococcus in degradation of malachite green wastewater

The invention belongs to the field of microbial degradation of dyes, and relates to application of sinococcus in degradation of malachite green wastewater. The bacillus pumilus is a bacillus pumilus R12, and the bacillus pumilus is a bacillus pumilus R12. When the initial concentration of malachite green MG is 200mg/L, R12 cells are 8.0 g/L, and the temperature is 30 DEG C and the pH value is 6.0, the reaction is performed for 30 minutes, and the degradation rate is 99.80%. When the initial concentration of MG is 1000 mg/L, the degradation rate can reach 95% or above after the reaction is carried out for 1.5 h. Meanwhile, the R12 has wide pH adaptability and temperature adaptability when used for degrading malachite green, and malachite green MG can be efficiently degraded under the conditions that the pH ranges from 5.0 to 10.0 and the temperature ranges from 10 DEG C to 45 DEG C. 本发明属于染料的微生物降解领域，涉及一种奇异球菌在降解孔雀石绿废水中的应用。所述的奇异球菌为Deinococcus wulumuqiensis R12。本发明在孔雀石绿MG初始浓度200mg/L，R12细胞为8.0g/L时，30℃，pH 6.0的条件下反应3
