Antibacterial Spectrum and some other Characteristics of an Antimicrobial Factor produced by Yersinia Ruckeri

Anlibakterielt spektrum og enkelte karakteristiske egenskaper for en aniibakteriell faktor produsert av Yersinia ruckeri

Abstract

Yersinia ruckeri produces an antibacterial factor which inhibits the growth of a wide spectrum of Gram-negative and Gram-positive bacteria, though not other strains of Y. ruckeri. The antibacterial factor was produced at low temperatures (4–20°C), but not at 37°C. The activity was lost after treatment of the supernatant with chloroform, UV-light and after boiling of the supernatant. One did not succeed in obtaining the antibacterial factor in a sterile solution.

Sammendrag

Det ble funnet at Yersinia ruckeri produserer en an ti bakte ri ell faktor som hemmer veksten av et vidt spektrum av Gram-negative og Gram-positive bakterier, men den hemmer ikke veksten av andre stammer av Y. ruckeri. Faktoren dannes ved lave temperaturer (4°C–20°C), men ikke ved 37°C. Aktiviteten ble borte etter behandling av supernatanten med kloroform, UV-lys og etter koking av supernatanten. En lyktes ikke i å fa separert den antibakterielle faktoren fra bakte ri esuspen sjoner.
