Molecular analysis of mercury-resistant Bacillus isolates from sediment of Minamata Bay, Japan.
Bacillus isolates from Minamata Bay sediment were selected for the ability to volatilize mercury from a range of organomercurials (including methylmercury). Chromosomal DNA from 74 of 78 such strains hybridized with the mer mercury resistance operon DNA from marine Bacillus sp. strain RC607 (Y. Wang, M. Moore, H. S. Levinson, S. Silver, C. Walsh, and I. Mahler, J. Bacteriol. 171:83-92, 1989). T...
متن کاملDiversity of mercury resistance determinants among Bacillus strains isolated from sediment of Minamata Bay.
Thirty mercury-resistant (Hg R) Bacillus strains were isolated from mercury-polluted sediment of Minamata Bay, Japan. Mercury resistance phenotypes were classified into broad-spectrum (resistant to inorganic Hg(2+) and organomercurials) and narrow-spectrum (resistant to inorganic Hg(2+) and sensitive to organomercurials) groups. Polymerase chain reaction (PCR) product sizes and the restriction ...
متن کاملOrganomercurial-volatilizing bacteria in the mercury-polluted sediment of Minamata Bay, Japan.
A total of 4,604 bacterial strains isolated from the sediments of Minamata Bay and nearby low-level-mercury stations (control stations) were screened for the ability to volatilize mercury from inorganic and organic mercurial compounds. The strains that volatilize mercury from several kinds of organomercurials were found only in the sediments of Minamata Bay.
متن کاملA new mass screening method for methylmercury poisoning using mercury-volatilizing bacteria from Minamata Bay.
A simplified mass screening method for methylmercury exposure was developed using methylmercury-volatilizing bacteria from Minamata Bay. Some bacteria can transform methylmercury into mercury vapor. Most mercury in the hair is methylmercury, which is readily extracted with HCl solution. Black spots are formed on X-ray film due to the reduction of Ag(+) emulsion with mercury vapor produced by me...
متن کاملMolecular Analysis of vanHAX Element in Vancomycin Resistant Enterococci Isolated from Hospitalized Patients in Tehran
Background: Vancomycin (glycopeptide)-resistant enterococci (VRE or GRE) can cause serious problems for hospitalized patients due to the limited options for treatment of VRE infections. As infection with VRE increases in hospitals, further knowledge about vancomycin resistant genes is needed. Methods: Isolates of Enterococcus spp. were collected from hospitalized patients in Tehran (Iran) durin...
