MORPHOFUNCTIONAL FEATURES OF BACTERIA AND MICROMYCETES LIVING IN THE OLD GOLD MINING WASTES

Abstract

The aim of the work was to visualize morphofunctional condition of bacteria and microscopic fungi (micromycetes) directly multicomponent gold mining waste. Print preparations were obtained from long-time placer gold-concentrating plant wastes containing reserves of heavy metals, including gold and man-made mercury. When studying them with electronic microscope it was found out that bacteria, mold fungi and yeasts live in the wastes, individual conidia (sporules) can also be revealed. Bacteria are transformed into various options of L-forms and form a biofilm from the association of elementary bodies and rod-shaped cells without adsorption of visible dense particles. Elementary bodies retain the ability to divide, rod-shaped cells - to the formation of filamentous structures. Circular or oval sculpture formations are on the surface of yeast cells. Dead fragments of mycelium and conidia of unidentified mold fungi whose surface is covered with a variety of dense particles were found in big quantities. All biotic factors along with the dust and heavy metals affect the health of workers of riverbed gold mining.
