The chitinolytic activity of 171 strains of 15 species of spore-forming aerobic bacteria isolated from different ecological sources has been studied. 85 strains of the studied bacilli (50%) hydrolyzed colloidal chitin in a different degree. Among the cultures isolated from human and animal organism 60% of strains were characterized by the presence of extracellular chinases, among the collection strains--37%, among those isolated from soil and from insects--40 and 43%, respectively. The cultures of Bacillus subtilis as well as B. coagulans, B. megaterium and some other possessed the highest activity on the liquid medium. Some strains have been chosen for further research aimed at their possible use for biotechnology.
对从不同生态源分离出的15种产孢需氧菌的171个菌株的几丁质分解活性进行了研究。所研究的芽孢杆菌中有85个菌株（50%）不同程度地水解了胶体几丁质。在从人和动物机体分离出的培养物中，60%的菌株具有细胞外几丁质酶，在保藏菌株中为37%，在从土壤和昆虫中分离出的菌株中分别为40%和43%。枯草芽孢杆菌以及凝结芽孢杆菌、巨大芽孢杆菌和其他一些菌株在液体培养基上具有最高活性。已选择一些菌株进行进一步研究，旨在探讨它们在生物技术中的潜在用途。
