Biotechnological bases of use of natural mineral glauconite in soil-forming processes at development of technogenic massifs and liquidation of enterprises on extraction of minerals
To initiate the process of soil formation, it is necessary to introduce a culture of microorganisms capable of improving mineral nutrition, plant growth and resistance to adverse factors, regardless of the mineralogical composition of the surface. The advantage of the developed methods is the multifunctionality of the sorbent, which is an abiotic catalyst: the dangerous agent binds physically due to the formed fine-porous structure, and chemically due to the ion exchange processes occurring due to the nature of the layered glauconite silicate. The viability of immobilized glauconite bacterial cells of Agrobacterium radiobacter 204, Rhizobium leguminosarumbiovartrifolii, Flaviobacterium L 30 fulvum, Pseudomonas aureofaciens 1393 BS, amounted to no less than 4 months., while the original biological products are stored no more than 1 month. Key words: glauconite, sorbent, sorption capacity, heavy metals, microorganisms, immobilization on inorganic carriers.
