【摘要】 为研究微生物对土壤中酚污染的净化能力,培养分离出了一株能有效降解酚的芽孢杆菌,并通过土柱试验研究了其降解特性和影响因素。结果表明,该芽孢杆菌在温度为16℃~30℃时,对浓度为50~500mg L-1范围内的酚污染(相当于10~l00μg g-1的土壤酚含量)降解率高达96.1%以上,且对pH值适应范围较大。更多还原

【Abstract】 To study phenol-degradation of microorganism in soil,one phenol-degrading microorganism was isolated and it was identified as Bacillus sp.The Characters and factors of biodegradation were studied by means of batch biodegradation soil column experiments.It was found that the rate of degradation was up to 96.1% at 16℃-30℃,when concentration was 50-500mg L^-1（ie.10-100 microgramme phenol per gram soil） and the strain also tolerated a wide pH.更多还原
