Abstract

By quantifying carbon fixation in obligate heterotrophic bacteria across the global ocean, we show that about 20% of dark dissolved inorganic carbon (DIC) fixation arises from anaplerotic processes — reaching up to almost half of dark DIC fixation in some regions or conditions.

黑暗海洋中的异养细菌是二氧化碳固定的主要贡献者

通过量化全球海洋中专一性异养细菌的碳固定，我们发现大约20%的暗溶解无机碳（DIC）固定来自于回融水过程——在某些地区或条件下几乎达到暗DIC固定的一半。
