Abstract Enzymatic phosphate release was studied in water from three small lakes in the subarctic region of northern Sweden. Free dissolved hydrolytic enzymes were shown to release considerable amounts of phosphate from autoclaved lake water. It was possible to show that phosphate was enzymatically released from particulate matter by exposure of autoclaved, 32P-labelled plankton to lake enzymes followed by characterization of degradation products with gel chromatography. Seston turned out to be vitally important as a phosphorus source for planktic organisms since plankton inoculated in lake water freed from seston were shown to produce high activities of phosphatase.
