Metabolic switching between inorganic and organic phosphorus sustains microbial activity in an ultraoligotrophic ocean

Abstract Phosphorus scarcity constrains microbial activity in parts of the oligotrophic ocean, yet the extent to which dissolved organic phosphorus (DOP) supports microbial P demand remains unresolved. Here, we quantified the concentrations, turnover times, and uptake kinetics of...
