The methylation of mercuric chloride by human intestinal bacteria

Abstract
Most strains of staphylococci, streptococci, yeasts andE. coli isolated from human faeces, could synthesize methylmercury compounds. In contrast, few strains of obligate anaerobes could do so. Up to 6 ng methylmercury/ml were formed in 44 h from 2 μg mercuric chloride.
