Isolation and Preliminary Characterization of Twenty Bacteriophages Infecting Either Brevibacterium or Arthrobacter Strains

Abstract

Thirty-seven bacteriophages plaquing on Corynebacterium, Brevibacterium , or Arthrobacter strains were isolated from soil or vegetation samples. Restriction analysis of phage DNA indicated that 20 phages were unique; one of them produced entirely turbid plaques on Brevibacterium ketoglutamicum and was characterized as temperate. All these phages were assigned to group B of the classification of Bradley (Bacteriol. Rev. 31:230-314, 1967) and had relatively narrow host ranges.
