摘要: 研究了不同油浓度污染土壤经过两个为期125 d的生物修复后的土壤中过氧化氢酶、多酚氧化酶和脂肪酶的酶活变化,分析了土壤中3种酶活性的变化特征与规律。结果表明,随着油浓度的增加,土壤中过氧化氢酶和多酚氧化酶的活性下降,脂肪酶活性增加;经过生物修复后,土壤中的过氧化氢酶和多酚氧化酶的活性在第二周期要比第一周期提高,而脂肪酶活性下降;这3种土壤酶活性变化受污染物浓度影响不显著,但不同浓度油污染土壤的修复对过氧化氢酶的影响要大于对多酚氧化酶和脂肪酶的影响。

Abstract: This paper studied the variations of catalase(CAT),polyphenol oxidase(PPO) and lipase in soils contaminated by different concentration oil after bio-remedied for two durations of 125 days.The results showed that the activities of CAT and PPO in the soils were decreased,while that of lipase was increased with increasing oil concentration.After the second duration of remediation,the activities of soil CAT and PPO were higher than those after the first remediation duration,while that of lipase was in inverse.The activities of these three enzymes were not significantly affected by oil concentration,but the bioremediation of soil contaminated by different concentration oil had more significant effect on CAT than on PPO and lipase.
