摘要:A strain DACO-6 capable of highly degrading chlorothalonil was isolated from soil. The strain DACO-6 was identified as SporolactobaciUus terrae based on 16S rRNA and analysis of morphology, physiological and biochemical characters. The optimal pH value and temperature were 7.0-7.5 and 35°C. The 5d degradation rate of 50 mg/L chlorothalonil by strain DACO-6 could reach about 95.2% in inorganic salt medium. The strain DACO-6 also had high tolerance to chlorothalonil. It could tolerate at least 800mg/L chlorothalonil under the experimental conditions. Adding humus soil in the medium could significantly increase the degradation rate of chlorothalonil by the strain DACO-6. It was believed that the strain DACO-6 could be used for control of chlorothalonil pollution.
