MICROBIOLOGICAL CHARACTERISTIC OF THE SHEHERCHAY RIVER AND SHEHERCHAY RESERVOIR

Abstract

Microbiological characteristics of the Sheherchay river and the Sheherchay reservoir formed in the river bed in 2004 were determined for the first time for the seasonal changes of 2009. The total number of water and soil microorganisms, quantitative and qualitative composition of the saprophytic and some physiological groups of bacteria are assessed. It is shown that the upper reaches of the river are environmentally stable in all seasons. At the same time, the middle part of the river is locally enriched with allochthonous organic matter from human settlements. Before inflowing into the water reservoir, water becomes stable and the increase in the saprobic degree is not observed. In the reservoir, the development of microbiota is closely related to abiotic factors of the region and the environment. Seasonal changes in the number and physiological activity of microorganisms is most strongly manifested in the water, whereas the generation of microorganisms in the soil is less pronounced. Water in the river and the reservoir is mesosaprobic and mesotrophic.
