title: The diversity of mercury reductases among mercury-resistant bacteria.
abstract: Two immunologically non-cross-reactive types of mercury reductases were found among Gram-negative and two among Gram-positive mercury-resistant environmental bacteria. Mercury reductases were further discriminated by 'spur' formation immunodiffusion tests. Immunologically indistinguishable mercury reductases were found among strains belonging to phylogenetically distant genera. This suggests a horizontal transfer of mercury resistance genes between these strains.
