DIFFERENTIATION OF ERWINIA AMYLOVORA, ERWINIA CAROTOVORA, AND ERWINIA HERBICOLA
Fermentation of glucose, nitrate reduction, nitrate respiration, nucleoside phosphotransferase, and pectolytic activity were tested on 132 strains of the genus Erwinia obtained from the culture collections. All the strains of Erw. Amylovora formed taxonomically homogeneous group, while the strains designated as Erw. Amylovora var.

Polygalacturonase of Erwinia carotovora
Abstract The polygalacturonase, clearly differentiated from polygalacturonic acid trans-eliminase, produced in the culture fluid of Erwinia carotovora was purified 56-fold by means of acetone precipitation, acetate buffer extraction, and two successive treatments by chromatography on carboxymethyl cellulose.

Comparison of pectic enzymes produced by Erwinia chrysanthemi, Erwinia carotovora subsp. carotovora, and Erwinia carotovora subsp. atroseptica [PDF]
Erwinia spp. that cause soft-rot diseases in plants produce a variety of extracellular pectic enzymes. To assess the correlation between patterns of pectic enzyme production and taxonomic classification, we compared the enzymes from representative strains.

Lactose metabolism in Erwinia chrysanthemi [PDF]
Wild-type strains of the phytopathogenic enterobacterium Erwinia chrysanthemi are unable to use lactose as a carbon source for growth although they possess a beta-galactosidase activity. Lactose-fermenting derivatives from some wild types, however, can be obtained spontaneously at a frequency of about 5 X 10(-7).
