Abstract: | There are increasing concerns over compound pollution in northeast of China and its bioremediation. Cd, Phe, degradation bacteria
W.J and their combination on soil microbial community function were assessed with the BIOLOG method. The microbial community
was extracted from the soil with different treatments. Average color development, richness, Shannon–Weaver index, and principal
component analysis on OD standardized data were performed. The results showed that soil microbial metabolic diversity in CK
was significantly higher than that in the soils in which Cd, Phe, W.J or their combination was added. It indicated that Cd,
Phe has significantly negative effect on the sole-carbon-source metabolic ability of soil microbial communities, particularly
when both of them were present. Application of degradation bacteria incubation makes soil microbial communities same as control
except for the significant decrease in 4-hydroxy benzoic acid, l-serine, glucose-1-phosphate metabolism. It shows that the incubate application has a considerably effect in soil communities
reversion. |
