THE STUDY OF TOXIC RESISTANCE OF BIOFILMS MICROORGANISMS (THE CASE STUDY OF THE SPECIES NITROSOMONAS EUROPAEA)

The report addresses the issues of the microorganisms functioning type Nitrosomonas europaea , in biofilms of sewage treatment plants, municipal wastewater, under the prolonged influence of one of the derivatives of PAHs, benzo[a]pyrene. There are issues of the biological effectiveness of the species Nitrosomonas europaea in microbiological wastewater treatment (the case study of the benzo[a]pyrene oil product). Associated factors such as the influence of temperature, pH of the acidity of the aquatic environment, chemical oxygen consumption and biological oxygen consumption, combined with the influence of the above component, on the state of the species Nitrosomonas europaea are also given.
