Inhibition of Erwinia amylovora by Bacterium sp. isolated from fire blight cankers

Farabee, G. J.; Lockwood, J. L.

At the Ohio Agricultural Experiment Station, Wooster, a non-pathogenic, yellow Bacterium sp., frequently isolated together with E. amylovora from cankers on pear and apple, inhibited the growth of the pathogen in culture, apparently by increasing the acidity of the medium to an unfavourable level.
