Isolation of Highly Efficient Phenol Degradation Strain and Characterization of Degradation of Phenol

[摘要] The biodegradation of phenol was carried out from the sludge in the sediment of the chemical plant in the Heilongjiang Chemical Industry Group. The phenol was used as the only carbon source of the inorganic salt medium to obtained from the biodegradable strain of phenol to obtain more efficiency antimicrobial phenol and study its degradation characteristics. The phenol degradation rate of FB-2 was the highest, 87.9% and the phenol degradation is FB-4, which is 65.5%. pH7.2, the degradation rate of phenol was about 78.0%, and the degradation rate of phenol was 56.9%. When the phenol concentration was 100 mg/L, the degradation rate of phenol was reduced to 38.8% when the phenol concentration was 91.2% and the concentration of phenol increased to 2200 mg/L. The optimum conditions for inoculation were 20%, the pH was equal to 7.1, the temperature was 25°C, and the strain was screened with high efficiency phenol degradation, named FB-2.
