[Extracellular protease activity in cryosphere components].
The extracellular protease activity was studied in the snow of sea and land ecosystems, core of pack ice, and sea water of Arctic for estimation of dynamic (enzymatic) processes of organic matter transformation in components of the natural ecosystems. Spatial and vertical distributions of extracellular enzymatic activity were established. The ecological situations in the studied regions was estimated using the express azocasein--trypsin test-system.
