SELECTION OF BACTERIA DEGRADING SODIUM PENTACHLOROPHENOLATE

The ability to degrade sodium pentachlorophenolate (concentration 0.75 mM or 1.0 mM) has been studied in bacteria isolated from soils of different regions of Georgia, under the conditions of deep cultivation. Several strains capable of degrading over 90% of sodium pentachlorophenolate were revealed. All investigated cultures degraded better Na-PCP in the presence of glucose, an additional source of carbon, in the nutrient medium. The strain under conditional number 9J52, degrading sodium pentachlorophenolate by dechloridation, displayed the best result. Introduction of toxicant into nutrient medium at different stages of culture growth has no significant impact on biomass accumulation.
