Biofilms from the Kapova Cave Walls as a Source of Hydrolase Producers

Researchers have discovered that bacterial biofilms from the walls of Kapova Cave, part of the UNESCO World Heritage Site Shulgan-Tash Nature Reserve, harbor strains with significant potential for producing extracellular hydrolytic enzymes. The study identified that 89% of the isolates belonged to Proteobacteria, with notable producers of protease, RNase, and amylase being Stenotropomonas rhizophila, Lysinibacillus fusiformis, and Pseudomonas stutzeri, respectively. This finding highlights the biochemical diversity and potential biotechnological applications of microorganisms from extreme environments like karst caves.
