Typing of fluorescent phytopathogenic pseudomonads by bacteriocin production

Abstract

Several phytopathogenic fluorescent Pseudomonas species, primarily P. syringae, could be grouped into 16 bacteriocin producer groups, including new and previously described groups. At least 86% of the P. syringae strains could be typed by bacteriocin production. There was poor correlation between bacteriocin type and host plant origin. No correlation was detected between syringomycin (a phytotoxin) production and bacteriocin type.
