摘要
The extreme physicochemical conditions of deep sea hydrothermal system have raised special ecosystem that barely depends on sunlight. This kind of ecology is supported by chemoautotrophic microorganisms,which are primary producers in hydrothermal system. Iron oxidizing bacteria is one of such microorganisms in seafloor hydrothermal environment,and they can gain energy through chemical reaction that oxidizes ferrous iron. They have important influence on the process of seafloor biogeochemical cycles,the formation of metal deposit and enrichment of the ecosystem functions in the deep sea hydrothermal environment. This paper is about the iron oxidizing bacteria that widely exist in deep sea hydrothermal environment,as well as their classification,mechanisms for oxidizing iron and the concomitant biomineralization phenomena.
