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 Stenotropomonas rhizophila, Lysinibacillus fusiformis, and Pseudomonas stutzeri, respectively.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
