Jointly toxic effects of acetochlor and Cu~(2+) on indigenous bacterial communities in phaeozem were studied using the traditional toxicity assessment methods combined with the modern molecular techniques. It was indicated that acetochlor and Cu~(2+) had a synergic inhibitory effect on the amount of culture-dependent viable bacteria including nitrogen-fixing bacteria, silicate bacteria and phosphorus-mineralization bacteria, as well as the activity of soil dehydrogenase. The increase in the substrate-induced respiration (SIR) was significantly promoted by the two pollutants. Analyzing the similarity and the banding patterns by the denaturing gradient gel electrophoresis (DGGE) revealed that the joint toxicity of acetochlor and Cu~(2+) can significantly affect bacterial community structure. Microbial structures of the polluted soils and the clean soil without pesticide application were different, but there was a similarity in microbial structures between the soil with long-term pesticide application and the soil treated simultaneously with acetochlor and Cu~(2+) under the experimental condition, of which the similarity coefficient was up to 74.1%.

It is reported that without cultivation, DNA could be directly extracted from environmental samples with molecular biological methods, such as polymerase chain reaction(PCR) and denaturting gradient gel electrophoresis(DGGE). To analyze the community diversity of activated sludge and bio-film in the municipal sewage, work was done to directly extrude crude DNA from activated sludge and bio-film samples, separate and amplify 16S rDNA by PCR and sequence it with DGGE. The results show the significant microbe community difference between cultivated and uncultivated activated sludge. Further research on the community diversity of two different sewage treatment processes was done and initial discussion on the microbial distribution in the same reactor and microbial structure in different experimental conditions was carried out. The sequences of several 16S rDNA DGGE fragments were determined and some possible bacteria were confirmed in comparision in GeneBank(NCBI). The results show that the PCR-DGGE technology combined with sequences determination is a feasible and efficient method for microorganism analysis in environmental sample.

通过PCR DGGE等分子生物学技术可以不经过常规培养直接从活性污泥和生物膜样品中提取DNA ,对 16SrDNAV3区进行PCR扩增 ,结合DGGE(变性梯度凝胶电泳 ) ,从而分析活性污泥与生物膜中微生物种群结构 .研究证实 ,活性污泥培养前后微生物种群结构发生很大的改变 .同时对 2种污水处理工艺中微生物种群结构进行了对比研究 ,对同一反应器不同位置微生物分布以及不同工况下的微生物种群结构进行了初步探讨 .测定了活性污泥中部分菌种的 16SrDNAV3区片段序列 ,通过NCBI(美国国立生物技术信息中心 )基因库比对 ,初步确定细菌的属 .结果显示 ,PCR DGGE结合测序技术是一种完全可行的快速进行环境学样品微生物研究的分析方法
