Abstract Alkaline phosphatase activity (APA) of unfiltered andfractionated (algae, bacteria, dissolved) surface watersamples was measured using a spectrophotometric method in LakeŁuknajno from May to September 1993. The total enzymaticactivity varied between 0.44–2.35 µmol l−1h−1.Algae were major producers of alkaline phosphatase activity insurface water of the lake from May to August, and theiractivity constituted on the average 67% of the total APAactivity in the water. APA activity in bacterial size fractionwas low and constituted 9.6% (mean) of the total activity.The activities of free (dissolved in water) enzymes wererelative high during the time of study. This study show thathydrolysis of organic phosphomonoesters by alkalinephosphatase was negligible in the recycling of phosphorus inŁuknajno Lake.
