Inducible surface proteins from some strains of Pseudomonas species bacteria while adapting to cobalt

The possibility of increasing resistance of some Pseudomonas strains to cobalt at adaptation to monotonous increasing its concentration was studied. Strains Pseudomonas fluorescens B5242 and Pseudomonas fluorescens B894 are capable to increase its resistance in such conditions via inducible synthesis of protective surface proteins. The molecular masses of such proteins were 55.0; 45.0 and 33.0 kDa for P. fluorescens B5242 strain.
