摘要:
研究外加不同浓度胞外聚合物(EPS)对芽孢杆菌和黑曲霉降解土壤中芘效果的影响。结果表明,在100 mg/kg 芘污染土壤中添加芽孢杆菌EPS由411.78 mg/kg增加到2 779.54 mg/kg,土壤中芘的残余浓度减少 6.27 mg/kg;向土壤中接种芽孢杆菌0.86亿CFU/kg,芘的降解率为36.99%,EPS由411.78 mg/kg增加到 2 779.54 mg/kg,芘残留浓度下降到47.72 mg/kg。黑曲霉EPS由1 387.68 mg/kg增加到3 844.37 mg/kg,土壤中芘的残余浓度由42.36 mg/kg降至31.12 mg/kg;向土壤中接种黑曲霉1.0亿CFU/kg,EPS浓度由 1 387.68 mg/kg 增加到3 844.37 mg/kg,芘残留浓度降至38.15mg/kg。因此,真菌和细菌的 EPS具有较强的降解土壤中芘的能力,且EPS浓度越高土壤中芘的降解效果越好。
