【 摘 要 】

A laboratory-basedsimulation of exposure of the soil community in a gray forest soil to cadmiumand glucose has been conducted. It was established that while growing in afertile medium microbial communities isolated from a soil sample contaminatedwith cadmium have a substantially increased phase of growth delay and there isa reduction in total growth. While analyzing communities by Biolog Ecoplatemethod, it was found that, as compared to the community isolated from a soilrich in glucose, the community in a soil with cadmium is characterized bysignificantly lower AWCD, R and H indices, in which thedifferences increase with time of incubation. Also differences in the patternand rate of recyclable substrates have been revealed. The resulting datasuggest changes in the functional activity of the microbial community in thesoil under the influence of cadmium.
