A Broad spectrum Antiphage Strain Constituted with Protoplast Fusion Technology
Abstract: Antiphage mutants selected by 15 phage strains have resistant only to its relevant phage,50it is narrow-spectrum antiphage strain.The fusant ZG88 is obtained with protoplast fusion be-tween Corynebacterium pekinense 7338 and Corynebacterium crenatum Ts-Li.It s serologic reac-tion and phage attach test show that it has changed so much in cell surface structures as to losethe position of adsorption.So ZG 88 is a broad spectrum and steady antiphage strain.
