Abstract
SUMMARY
Strains of Pseudomonas pyocyanea and Shigella sonnei were tested for bacteriocine production both by the normal method and by a modification of it in which the producer strains were inoculated on to cellulose acetate membranes that had been placed on the surface of the culture medium. In only43.7 per cent, of 379 strains of Ps.pyocyanea were the results identical by the two methods.A higher correlation was noted in the case of Sh. sonnei and only 6 out of 89 strains of thisspecies gave different results by the two methods. We cannot recommend the use of cellulose acetate membranes in these bacteriocine typing techniques.
