NUMERICAL-ANALYSIS OF PSEUDOMONAS-FLUORESCENS BACTERIA ACCORDING TO THEIR LIPOPOLYSACCHARIDE STRUCTURE

Numerical analysis of bacterial strains representing different biovars (A, B, C, F, G, and i) of Pseudomonas fluorescens and nonfluorescent bacterial strains of P. alcaligenes, P. pseudoalcaligenes, and P. frag i was conducted according to the quantitative characteristics of their lipopolysaccharide composition. These bacterial strains have a high d egree of heterogeneity according to this index (similarity coefficient varied within 41-71%). The P. fluorescens 2763 strain, representing b iovar G, was the most taxonomically remote (similarity coefficient wit h other strains was only 41%). Nonfluorescent pseudomonads were simila r to P. fluorescens representatives which correlated with their classi fication according to phenotypic and genotypic traits.
