Emerging research on characterizing the potential of cable bacteria for CH4 mitigation

Abstract

Methane (CH4) contributes an essential portion for global warming as a pivotal greenhouse gas. Microorganisms are identified as an effective way to mediate and control CH4 emission. Cable bacteria is a promising microorganism to mitigate CH4, however, the studies of distribution, abundance and function for CH4 reduction of cable bacteria in inland water still remain unclear. In this paper, we propose the probable CH4 mitigation metabolism within cable bacteria in anoxic condition, and present the future research directions about the application potential of cable bacteria in CH4 reduction. The viewpoint will help to understand the significant role of cable bacteria in CH4 mitigation and provide a potential way to control CH4 emissions in inland freshwater ecosystem.
