A sulfate-reducing bacteria(SRB) strain, named GY-2,was isolated from groundwater in a 705 m deep aquifer at a coal mine in Huaibei Plain for mechanism analysis on the abnormally low sulfate concentration in the coal measure strata groundwater, and was identified as Desulfotomaculum guttoideum by Phylogenetic analysis based on 16S rRNA genesequence. The strain GY-2 is found to be anaerobes, mesophilic and suitable in neutral or alkalescent, low or medium water mineralization environment, and Fe2+ significantly promote the SRB strain growth. It is explained with the relationship between sulfate-reduction, redox potential and chemical types of groundwater, why the ratios of Due to image rights restrictions, multiple line equation(s) cannot be graphically displayed. change from high to low and to high again as the depths of the water-bearing strata increase continuously.
