| Abstract: | Two hundred and twelve strains representing 11 species of fluorescent pseudomonads along with an additional 198 strains isolated from the leaf and root surfaces of plants were tested for rutin glycosidase, on a mineral base medium supplemented with rutin and glucose. AH of the arginine dihydrolase negative phytopathogens (182 strains) with the exception of 12 of 12 strains of Pseudomonas syringae pv. glycina and one of 28 strains of P. syringae pv. phaseoticola showed rutin glycosidase activity whereas few of the arginine dihydrolase positive strains (22 of 228) were positive. |
