One hundred and twenty‐eight isolates representing 37 species and six genera of plant pathogenic and related bacteria were tested for the presence of /3–galactosidase, glucosidase. β‐glucosidase and β‐xylosidase; using nitrophenyl glycopyranosides as substrates. Agrobacterium tumefaciens, Corynebacterium flaccumfaciens, C. michiganense. Flavobacterium pectinovorum and Pseudomonas maltophilia showed activity on all of the four substrates. Xanthomonas albilineans and three nomenspecies of the X. campestris group had little or no o‐glucosidase activity but all other tests with Xanthomonas spp . were positive. None of the fluorescen; pseudomonads examined possessed β‐galactosidase but P. stizolobii, P. andropogonis and P. rubrisubalbicans , among the non‐fluorescent pseudomonads showed activity.
