Abstract
A large number mercury-resistant nitrogen-fixing bacteria were isolated by screening soil samples from agricultral farms of West Bengal, India. All of the samples were found to contain signficant quantities of mercury. Twenty five of the pure isolates were identified to the generic level following Bergey''s Manual of Determinative Bacteriology, 8th edition. These organisms were resistant to HgCl2 and a few of them were resistant to phenylmercuric acetate (PMA) as well. Their mercury resistance was also associated with antibiotic resistance properties. Growth of two mercury-resistant N2-fixing organisms was monitored in liquid media supplemented with HgCL2. The mercury volatilizing capacity of four mercury-resistant bacterial strains was also determined.This publication has 1 reference indexed in Scilit:
