Shotgun proteomic data of Desulfonema magnum

Sulfate-reducing bacteria (SRB) play a pivotal role in the global carbon- and sulfur cycles, especially in the marine environment. Here, continental margins, coastal ranges, and shelf sediments stand out by their high input of organic matter, and more than 50% of their mineralization is achieved in the upper sediment layers, coupled to sulfate reduction. This turnover is mainly achieved by members of the family of Desulfobacteraceae of completely oxidizing SRB. Desulfonema magnum is a member of this family.

硫酸盐还原菌（Sulfate-reducing bacteria, SRB）在全球碳、硫循环中发挥关键作用，尤其在海洋环境中。其中，大陆边缘、海岸带与大陆架沉积物因有机质输入量极高而尤为突出，其超过50%的有机质矿化过程发生在沉积物上层，并与硫酸盐还原作用相耦联。该物质周转过程主要由脱硫杆菌科（Desulfobacteraceae）下的完全氧化型硫酸盐还原菌类群介导完成。大型脱硫线菌（Desulfonema magnum）便是该科的一员。
