title: [Analysis of the basic protein fractions of the outer membrane in E. coli strains differing in survivability in air].
abstract: The study of the spectrum of the main fractions of proteins contained in the outer membrane of E. coli strains has revealed the relationship between the composition of protein fractions in the outer membrane and the level of the survival of these bacteria in the air. The increased survival capacity of E. coli strain K12 after the transfer of pSA 50 plasmid has been found to correlate with the appearance of 2 molecular fractions in the outer membrane. The positions of these fractions correspond to the molecular weights 70,000 daltons and 80,000 daltons.
