Marine microorganisms play a fundamental role in the global carbon cycle by mediating the
sequestration of organic matter in ocean waters and sediments. A better understanding of
how biological factors, such as microbial community composition, influence the lability and
fate of organic matter is needed. Here, we explored the extent to which organic matter
remineralization is influenced by species‐specific metabolic capabilities. We carried out
aerobic time‐series incubations of Guaymas Basin sediments to quantify the dynamics of …
