Coal mining and coal preparation dumps are on the one hand as environmentally hazardous, on the other hand - commercial significance, in terms of content of rare metals raw materials. Biotechnological methods are most justified for its processing to recover valuable components and reduce toxicity. Implementation of microbial biotechnology should be based on comprehensive studies of biological and physico-chemical properties of the initial solid substrates, a consortium of microorganisms, which are present, followed by selection, screening and selection of the most promising high active strains to create effective bacterial drug. From the aboriginal community coal tailing in pure cultures were isolated three strains dominating mesophilic and moderately thermophilic acidophilic hemolitotrophic bacteria. The study of basic biological properties suggesting isolated strains belonging to the genus Acidithiobacillus, including Acidithiobacillus ferrooxidans, and genus Sulfobacillus. Comparison of the oxidative activity of isolated strains and aboriginal communities in relation to withdrawal from the substrate of rare and heavy metals is in favor of the consortium as a result sintrophic relationships of microorganisms in the community. This must be taken into account when creating the optimal effective bacterial drug for the man–made substrate. [ABSTRACT FROM AUTHOR] |
