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.
研究了保护性涂层细菌破坏剂在不同生长模式（生物膜和浮游生物）下的脂肪分解和过氧化氢酶活性。结果表明，生物膜中外酶的合成有所不同。生物膜中细胞外脂肪酶和过氧化氢酶的活性分别比浮游生物中的高1.1 - 1.5倍和1.2 - 2.1倍。将实验持续时间延长至14天，脂肪分解活性显著降低。由细菌破坏剂产生的所研究酶的活性可用于评估隔离涂层的生物抗性，作为其在技术介质中生物降解的指标。
