isolation of mercury resistant bacteria and influence of abiotic factors on bioavailability of mercury -- a case study in pulicat lake north of chennai, south east india.pulicat lake sediments are often severely polluted with mercury compounds and other toxic heavy metals. several mercury-resistant bacteria were isolated and identified from the sediments and all the isolates exhibited broad spectrum resistance (both organic and inorganic mercuric compounds). mercury volatilization showed that four of the isolated bacillus cereus strains were able to reduce water soluble ionic form of mercury into volatile form via the well known enzymatic reduction. the effect o ...200616504251
