The effect of long-term exposure to manganese(Mn) on the soil microbial community was investigated in paddy soil from seven samples with different levels of manganese. The contents of total manganese were measured (114-4 611 mg/kg). The soil DNA was extracted and purified to PCR. The genetic diversity of the soil microbial communities was analyzed by DGGE (denaturing gradient gel electrophoresis) of a conservative region of 16S rDNA gene. The results indicated that species which were found in heaviest manga...
