Using BIOLOG-GN plates, this article describes the carbon sources metabolic characteristics of airborne microbial communities in a free surface-flow constructed wetland in different seasons and clarify the correlation between airborne microbial metabolic functions and environmental factors. The average well color development (AWCD), carbon metabolic(More)
To determine the community structure of airborne microbes in Qingdao downtown in autumn, the airborne bacteria and fungi were collected by the KC-6120 air sampler and analyzed using the 16S/18S rDNA gene clone library method. Phylogenetic analysis of airborne bacteria showed that they belonged to six major phylogenetic groups: Proteobacteria (78. 8%),(More)
The aim of this study was to investigate the effect of different primers in PCR-DGGE and PCR-RFLP on the analysis of microbial community in activated sludge. 8 pairs of primers were chosen to amplify the variable region of 16S rDNA for PCR-DGGE analysis, while 11 pairs of primers were used to amplify the total length of 16S rDNA for PCR-RFLP analysis. The(More)
The effect of glucose and elemental sulfur on the growth and PHB accumulation of Acidiphilium cryptum DX1-1 was investigated. Meanwhile, the differential expressions of 19 genes related with PHB accumulation, sulfur metabolism and carbon fixed in heterotrophy, phytotrophy and mixotrophy were studied by RT-qPCR. The results showed that strain DX1-1 could(More)
There are numerous microorganisms, especial pathogens, in the discharges. Those microorganisms are discharged into the river and sea through sewage outfalls, which results in possible health risks to coastal populations. And more attention should be paid to municipal discharges in developing countries. This study investigated the microbial community in the(More)
