Abstract
Bacteria were isolated from soil samples, containing high exchangeable lead concentrations, obtained from a busy freeway in the Mexico City metropolitan area. Forty-five selected strains (86.7% Gram-positive) h ad a single MIC distribution pattern for lead (800-1600 mu g/ml lead n itrate) and were considered lead-resistant. The isolates showed variab le levels of resistance to arsenate (86.7%), chromate (66.7%), cadmium (57.6%), and mercury (31.1%) ions. Multiple inorganic-ion resistance was shown by all strains.
