A study on microbial functional groups producing a climate related gas in the ocean. marine metagenome

Dimethylsulfoniopropionate (DMSP), the precursor of dimethyl sulfide (DMS), is mainly produced by marine phytoplankton, and is one of the most important sulfur and carbon sources for marine bacteria. To reveal the abundance and distribution of bacterial DMSP-degrading genes and the corresponding bacterial communities in relation to DMS and DMSP concentrations in seawater, we performed deep sequencing of environmental DNA obtained from DMS hotspot samples in the Pacific Ocean.

二甲基巯基丙酸内盐（Dimethylsulfoniopropionate, DMSP）是二甲基硫（dimethyl sulfide, DMS）的前体物质，主要由海洋浮游植物（marine phytoplankton）产生，是海洋细菌最重要的硫源与碳源之一。为揭示降解DMSP的细菌基因的丰度、分布特征，以及相关细菌群落与海水DMS和DMSP浓度的关联，我们对取自太平洋DMS热点区域样本的环境DNA（environmental DNA）开展了深度测序。
