PHYSICOCHEMICAL AND MICROBIOLOGICAL CHARACTERISTICS OF THE WASTE DUMPS AFTER COAL ENRICHMENT
Journal Title: Мікробіологія і біотехнологія - Year 2016, Vol 0, Issue 2
Abstract
Aim. The physical-chemical and microbiological characteristics of technogenic substrates depending on the duration of their storage have been studied. Methods. Atomic emission and atomic absorption spectroscopy, potentiometric method and the author’s patented electrochemical cell, standard microbiological method of cumulative cultures. Results. It was established, that during long storage of waste dumps there occurs the components concentration and oxidation of metal ions, that were found in the waste dumps, to the highest degree of oxidation and were formed more stable equilibrium structures. The effect of indigenous microbiota of waste dumps to increase their resistance to the processing has been shown. As it has been shown the indigenous microbiota of waste dumps are facilitated of increase their resistance to the recycling. The cumulative culture of microorganisms of different physiological groups forming microbiocenosis of waste dumps were obtained and quantified. The quantitative predominance of representatives of major groups of chemolithotrophic acidophilus bacteria (both mesophilic and moderately thermophilic) of indigenous microbiota from waste dumps with extended storage period, has been established. That, in turn, leads to a more pronounced effect of microbiota on the physicochemical characteristics of these waste dumps. Conclusion. The physical, chemical and microbiological changes are significant in storage dumps composition in the process of their accumulation. This should be taken into account in selecting the conditions of utilization of technogenic substrates by biotechnological methods using active members of their own microbiota.
