Five plasmid DNAs were detected in three of microorganisms, which formed microbial composition «Замин-М». One plasmid (23.1 kb) was found in Bacillus megaterium СКБ-310 cells and another one (55.0 kb) was found in cells of  Pseudomonas stutzeri СКБ-308, but cells of Bacillus subtilis СКБ-309 contained 3 plasmids (48.5 kb, 30.0 kb and 13.3 kb). It was assumed that these plasmids may carry genes of resistance to adverse environmental conditions, including the high content (10 %) of ions Cl- and SO42-.

Key words: plasmid, molecular length of DNA molecule, electrophoretic division.
