Higher concentration of Mercury ion (Hg 2+ ) and Methylmercury (CH 3 Hg + ) are very toxic to both macroorganisms and microorganisms. Many gram-positive and gram-negative bacteria can convert these toxic forms to relatively less toxic or non-toxic forms. Mercury resistant bacteria use enzyme organomercury lyase to degrade toxic form such as CH 3 Hg + to Hg 2+ and methane. These bacteria also employ the use of enzyme mercuric reductase to reduce Hg 2+ to Hg 0 .

Summary Introduction

Higher concentration of Mercury ion (Hg²⁺) and Methylmercury (CH₃Hg⁺) are very toxic to both macroorganisms and microorganisms. Many gram-positive and gram-negative bacteria can convert these toxic forms to relatively less toxic or non-toxic forms. Mercury resistant bacteria use enzyme organomercury lyase to degrade toxic form such as CH₃Hg⁺ to Hg²⁺ and methane. These bacteria also employ the use of enzyme mercuric reductase to reduce Hg²⁺ to Hg⁰.
