• Lipolytic and catalase activity of bacteria-destructors of protective coatings at different growth models: biofilm and plankton have been studied. It was shown that the synthesis of exoenzymes in the biofilm is different. Activity of extracellular lipase and catalase in the biofilm is 1.1-1.5 and 1.2-2.1 times higher, respectively, than in plankton. The experiment duration being increased to 14 days, the lipolytic activity considerably decreases. Activity of studied enzymes, produced by bacteria-destructors, can be used for estimating bioresistance of isolating coatings as the index of their biodegradation in technogenic media.
