Microbial community diversity, potential microbial activity, and metal resistance were determined in three soils whose lead contents ranged from 0.00039 to 48 mmol of Pb kg soil-1. Biomass levels directly related content. A molecular analysis 16S rRNAs suggested that each soil contained a complex, diverse community. statistical the phospholipid fatty acids indicated having highest content was not communities other soils. All active populations mineralized [14C]glucose. In all samples, 10 15% total culturable bacteria resistant had MIC for growth 100 150 &mgr;M.
