Seaweeds are fundamental components and primary producers in marine ecosystems, and their growth and decay significantly influence environmental conditions and microbial community structure. However, considerable debate persists regarding whether seaweed decomposition enhances marine carbon sequestration, and the role of microbes in seaweed degradation remains unclear. This study examined the degradation process of Sargassum under controlled laboratory conditions to assess its potential for carbon sequestration.
