项目摘要

The structure of microbial community was analyzed on sludge samples taken from the aerobic biofilter reactor by using clone libraries of 16S rRNA genes. Clone similar to Thiobacillus and Thiothrix was counted at 10 and 7, respectively, among 188 clones randomly selected from the libraries. Approximately 7% of DAPI stained total cells in the biofilter sludge hybridized with the probe Thio840 specific for Thiobacillus group. Real-time PCR using SYBR green I was employed with BONE663cF-Thio840R primer set to determine the copy number of 16S rRNA gene originated from Thiobacillus. High concentration of sulfide at 30 mg-S/L in the influent strongly enhanced abundance of the gene of 10^5 copies/ng levels in total DNA extracted from the aerobic biofilter sludge. the diversity of adenosine-5'-phosphosulfate reductase (apsA) genes, which produce a key enzyme for sulfate respiration and are present in all sulfate-respiring prokaryotes (SRPs), in UASB sludge was analyzed by cloning and sequencing techniques. The apsA amino acid sequence-based phylogenetic tree showed that the identified clones belonged to four groups : the sulfate-reducing bacterial group, Syntrophobacteraceae, Thiobacillus and the clone cluster group, distantly related to any previously described apsA clone. Real-time PCR quantification which used the primer sets specific for each of the four apsA gene sequences revealed that Desulfobulbaceae and Desulfovibrionales were the predominant species all of the sulfate-reducing bacteria in the UASB sludge throughout the experimental period. An excellent correlation of apsA gene abundance and behavior was found between the sulfate-reducing bacteria and Thiobacillus, as well as between Syntrophobacteraceae and the unknown apsA clone group.
利用16 SrRNA基因克隆文库分析了好氧生物过滤反应器中污泥的微生物群落结构。从文库中随机挑选188个克隆,与硫杆菌属和硫杆菌属相似的克隆分别为10个和7个。在生物过滤器污泥中,约7%的DAPI染色的总细胞与硫杆菌群特异性探针Thio 840杂交。采用SYBR绿色I荧光定量PCR技术,以BONE 663 cF-Thio 840 R为引物,检测硫杆菌16 S rRNA基因的拷贝数。进水中30 mg-S/L的高浓度硫化物强烈增强了从好氧生物过滤器污泥中提取的总DNA中基因的丰度,达到10^5拷贝/ng水平。利用克隆和测序技术分析了UASB污泥中硫酸盐呼吸关键酶腺苷-5 '-磷酸硫酸盐还原酶(apsA)基因的多样性。基于apsA氨基酸序列的系统发育树表明,所确定的克隆属于四个组:硫酸盐还原细菌组,共生细菌科,硫杆菌属和克隆簇组,远相关的任何先前描述的apsA克隆。实时PCR定量,其中使用的引物组特异性的四个apsA基因序列显示,脱硫ulfobulbaceae和脱硫弧菌目是优势物种的所有硫酸盐还原菌在UASB污泥在整个实验期间。硫酸盐还原菌和硫杆菌之间,以及共生菌科和未知的apsA克隆组之间的apsA基因丰度和行为的一个很好的相关性。
