Abstract:Impacts of long time drip-irrigation with oil-polluted water on microorganisms in reed rhizospheric soils were analyzed. Aftera six-month irrigation with oil-polluted water, the counts of bacteria at a -20 cm depth in soils were only 1/4 of those without oil-polluted water, but the growth and reproduction of hydrocarbon degraders were promoted. PCR-denaturing gradient gel electrophoresis profiles revealed that the structure of bacterial community was generally less affected, but the dominant flora was changed. Some members in phyla Proteobacterium and Bacteroidetes formed a stable, dominant community structure after the six-month irrigation with oil-polluted water, whereas the growth and reproduction of some members in phyla Firmicutes, Actinobacteria, and Cyanobacteria were obviously restrained.
