title: [Isolation, identification and degradation characteristics of bisphenol A degrading strain].
abstract: A bisphenol A(BPA) degrading strain B-16 was isolated from compost leachate of municipal solid waste. According to the morphological characteristics, physiological and biochemical, and sequence analysis of 16S rDNA, the strain was identified preliminarily as Achromobacter xylosoxidans. By tests in shaking flasks, the effects of the conditions of growth was studied, and it was determined that the optimum conditions were inoculum amount 0.6%, pH 7.0, and 30 degrees C. Under these conditions, when the initial concentrations were low (3, 5, 10 mg/L), the degradation reaction tallied with one order kinetic characteristic, while when in high initial concentrations (20, 50 mg/L), the degradation reaction can't be described by one order kinetic characteristic. When the initial concentration was 10 mg/L, the degradation rate was maximal, and it was 46.93%.
