Phenol Degradation Characteristics and Immobilization of Acinetobacte Strain HY1

The phenol degradation characteristics and immobilization of an Acinetobacte strain HY1 were carried out. The effects of phenol concentration, temperature, pH and NaCl dosage on the growth of HY1 and phenol degradation rate were investigated. The results showed that When the bacteria was cultured in 0.5 g/L phenol solution at 35 °C and pH 7.5 with shaking speed 120 r/min, liquid volume in flask 50 mL and inoculation amount 20 % for 6 h, the degradation rate of phenol was over 95 %. Compared with free bacteria, immobilized bacteria had a higher phenol degradation rate after a long culture time.
