Metal-resistant heterotrophic bacteria in coastal waters of Primorye Far Eastern State University, Vladivostok 690600 E-mail: Colony-forming heterotrophic bacteria were isolated from several locations in coastal waters of Primorye that differ in the level and character of heavy metals pollution. Statistically significant differences in minimum inhibitory concentrations of some metals were found for bacteria isolated from the environments with different levels of pollution. Bacterial strains that were highly resistant of several heavy metals also showed resistance to a wide spectrum of antibiotics and had a diversity of plasmids number and plasmids size. Bacteria of the family Enterobacteriaceae and the genus Pseudomonas were the dominant metal-resistant bacterial forms in polluted coastal wasters of Primorye. No strict correlation was found between metal resistance and taxonomic identity of bacteria. Key words: heavy metals, minimum inhibitory concentration, plasmids, antibiotics resistance. |
