- Abstract
- The studies of bacterial communities from extreme econiches are presently aimed mainly at analyzing the biodiversity of microorganisms using molecular biology methods. Cultivated bacteria from karst caves represent a unique group of microorganisms, the biochemical potential of which has been poorly studied. In the present work, bacteria from biofilms on the walls of the Kapova Cave (Shulgan-Tash Nature Reserve, Bashkortostan) were isolated and characterized in order to assess the ability of identified isolates to produce extracellular hydrolytic enzymes. Most of the isolates (89%) were members of the phylum Proteobacteria, with the remaining ones belonging to the phyla Actinobacteria, Firmicutes, and Bacteroidetes, which accounted for 5, 4, and 2% of the isolates, respectively. Strains with high levels of secreted protease, RNase, and amylase activity were identified as Stenotrophomonas rhizophila, Lysinibacillus fusiformis, and Pseudomonas stutzeri, respectively.
