RESISTANCE TO HEAVY METALS OF ACTINOBACTERIA ISOLATED FROM THE BIOLOGICAL FOULING OF SHELLFISH AND MUSSELS OF THE ODESA GULF OF THE BLACK SEA

SummaryEnvironmental pollution with heavy metals/metalloids is one of the most important environmental problems, which leads to development bioremediation strategies and search for biomarkers assess its condition. Aim. To determine sensitivity metals actinobacteria isolated from biological fouling natural shell rock mussels Odesa gulf Black Sea. Methods. Thirty-four strains were used in investigation. The studied bacteria metal cations was determined on starch-casein agar by disk diffusion method. Discs impregnated salts solutions Cu2+, Co2+, Ni2+, Cd2+, Zn2+ concentrations 0.001 mol/l, 0.01 0.05 0.1 0.5 mol/l 1.0 used. Results. investigated showed variable metals, depended source isolation, strain, type concentration. All tested sensitive Cd2+ (MIC mol/l), resistant higher than vast majority bacteria). At lower MIC, zinc stimulated formation aerial mycelium almost all strains, pigment increased some them. shellfish decreased following sequence: Cd2+>Cu2+>Co2+>Ni2+>Zn2+, – Cd2+>Cu2+>Ni2+>Co2+>Zn2+. Conclusions. Actinobacteria are more cadmium, cuprum, cobalt, nickel zinc, compared rock. highly mol/l) concentration range mol/l.
