BIOTECHNOLOGIES IN ENSURING THE QUALITY OF NATURAL WATER IN THE TSIMLYANSK RESERVOIR
The article discusses the issues of the state of natural water in the Tsimlyansk reservoir, suggests biotechnology aimed at preserving biological resources and improving water quality. The main factors affecting the state of natural water are natural biological processes in reservoirs and active human activity. The Tsimlyansk reservoir has been experiencing a high anthropogenic load for many years, gradually losing its ability to self-repair. Heated and enriched with organic, mineral substances, the surface layer of water creates favorable conditions for the vital activity of problematic biogens, causes the rapid development of blue-green algae. Bioremediation allows for suspending the degradation of the fishery reservoir, the Tsimlyansk reservoir, with unique natural complexes. Developed at the All-Russian Scientific Research Institute of Hunting and Breeding Named After Professor B.M. Zhitkov (Volgograd, Russia) biotechnology, which is the introduction of Chlorella vulgaris IFR No. C 111 strain into the bays of the Tsimlyansk reservoir makes it possible to improve the sanitary and hygienic indicators of water, reduce the blooming effect, improve the species composition of biological aquatic and coastal resources.
