- 요약Organosulfur has been increasingly recognized as a fundamental part of biogeochemical sulfur cycling in environmental systems, but many questions remain about the extent and nature of microbially-driven organosulfur cycling, the microbes mediating these transformations, and the relevance of these processes in the local and global cycling of labile elements. Here, I analyze shotgun metagenomic sequence data to characterize the microbial metabolisms that drive biogeochemical sulfur cycling, with a specific focus on the role of organic sulfur compounds as a source or sink of inorganic sulfur. My findings demonstrate the potential for tightly coupled organic and inorganic sulfur cycling in taxonomically diverse microbial communities inhabiting the deep subsurface, freshwater systems, oceans, and tidal flats. This widespread genomic potential supports the relevance of organosulfur cycling across systems and underscores a need to revise our conceptualization of sulfur cycling to acknowledge the potential impact of both inorganic and organic aspects of this cycle. Incorporation of organosulfur cycling pathways into existing conceptual frameworks of S cycling will offer new insights into microbial ecology, constraints on sulfur budgets, and elucidate the overall impact of OrgS cycling on larger Earth system processes.
