METHODS OF PURIFICATION OF DRINKING WATER FROM NITRATES BY MICROORGANISMS
The main task of the modern time is to preserve nature, including water resources for a decent life of future generations. In this article we set ourselves the task if recovery of nitrate compounds of cleaning drinking water by microorganisms. Most bacteria involved in cleaning are heterotrophs. It is noted that the quality of water in Turkestan had deteriorated dramatically increased its organic pollution. The largest part of nitrogen compounds in these waters is nitrate nitrogen (NO<sub>3</sub><sup>-</sup>). An attempt was made to explore the possibility of using cultures of microorganisms for water purification from nitrates by microorganisms. For this purpose the selected strains of Pseudomonas stutzeri Bacillus subtilis 18 and 19, capable of reducing nitrates to gaseous products. It turned out that selected strains are able to restore nitrogen compounds to gaseous products and to purify water using microorganisms.
