摘要:

利用Biolog-ECO技术分析不同青霉素浓度处理下土壤微生物的群落代谢活性及结构多样性,利用变性梯度凝胶电泳(denaturing gradient gel electrophoresis, DGGE)技术分析典型微生物群落结构变化情况,探讨青霉素对土壤微生物群落的生态毒理效应。主成分分析(PCA)结果表明,高浓度青霉素(400和800 mg·kg-1)处理能快速诱导土壤中以酚酸类化合物为碳源的微生物菌群富集。DGGE结果显示,在高浓度青霉素(800 mg·kg-1)胁迫初期,土壤中微生物多样性指数(Shannon-Wiener index)显著降低(P<0.05);7 d后,主要微生物群落结构随土壤中青霉素降解又逐渐恢复。

Abstract:

Effect of penicillin, varying in concentration, on metabolic activity and structural diversity of soil microbial community was analyzed with the Biolog-ECO technology, and changes in the soil microbial community structure were with the DGGE (denaturing gradient gel electrophoresis) technology, so as to explore eco-toxicological effect of penicillin on soil microbial community. PCA based on the BiologEcoplatesTM shows that penicillin high in concentration (400-800 mg·kg-1) may induce rapid enrichment of microbial groups that use phenolic compounds as carbon source in the soil microbial community. PCR-DGGE analysis reveals that in the soil treated with a high dose(800 mg·kg-1) of penicillin, Shannon-Wiener diversity index was significantly lowered in the first days and gradual recovered 7 days later with the penicillin in the soil degrading.

Key words: penicillin, microbial diversity, BiologEcoplatesTM, PCR-DGGE
