ELECTROPHORETIC COMPARISON OF ENZYMES IN THE STRAINS IN BIOVARS OF PSEUDOMONAS MALTOPHILIA

Abstract

Polyacrylamide gel electrophoresis with specific staining for six enzymes was used for comparison of the strains in two biovars in Pseudomonas maltophilia. The strains in biovar I required methionine for growth, while the strains in biovar II did not. On the basis of the similarity values on the electrophoretic relative mobilities of enzymes, the strains studied were divided into two major clusters. Out of 27 strains, 18 strains in biovar I were included in cluster 1, and two strains in biovar I and seven strains in biovar II were included in cluster 2.
