| Popis: | A total of 88 strains of Erwinia carotovora subsp. carotovora (Ecc) isolated from various host plants in several geographic regions were screened for production of antibacterial substances using the same strains as indicators. Of the 88 strains, 72 produced antibacterial substances. One of these 72 strains, a Brazilian strain Ecc 32, produced an antibacterial substance active against all tested Ecc strains on TSA medium. The antibacterial spectrum of the compound from Ecc 32 strain was limited to closely related strains of soft-rot Erwinia species. Such a narrow spectrum of activity is typical of bacteriocins. The compound produced by Ecc 32 strain, however, was resistant to some enzymes and detergents. Moreover, the compound was heat-stable and active over a wide pH range. The physical characteristics of the compound were not in agreement with those of bacteriocin or carotovoricin. |
