Abstract: Effects of bioremediation on microbial communities in soils
contaminated with petroleum hydrocarbons are a scientific problem to be solved.
Changes in dominate microbial species and the total amount of microorganisms
including bacteria and fungi in rhizospheric soils after bioremediation were
thus evaluated using field bioremediation experiments. The results showed that
there were changed dominant microorganisms including 11 bacterial strains which
are mostly Gram positive bacteria and 6 fungal species which were identified.
The total amount of microorganisms including bacteria and fungi increased after
bioremediation of microbial agents combined with planting maize. On the
contrary, fungi in rhizospheric soils were inhibited by adding microbial agents
combined with planting soybean.
