Abstract

APIZym strips were used for measuring the activity of 19 enzymatic reactions in marine sediment samples from the continental slope of the Celtic Sea in 135…1630 m depth. The activities of phosphatases were dominant followed by esterases, peptidases, and glycosidases. The activities were influenced by the sediment depth within the cores and the depth of the station. The results indicate that the APIZym system is able to resolve vertical stratification and spatial variability of enzymes possessing activity rates exceeding 10 nmol substrate h−1 cm−3 in sediment but not of those with lower rates which for example would be found in deep‐sea sediments.
