This study shows that alkaline phosphatase activity in marine bacteria supports carbon acquisition from dissolved organic phosphorus, even in phosphate-rich conditions.

The paper investigates phosphatase activity and gene expression in the California Current Ecosystem, finding atypical phosphatases drive DOP utilization despite Pi repletion.

This study shows that phytoplankton produce extracellular superoxide to acclimate to light stress, with DPI inhibiting this process and reducing photosynthetic health.
