The mol. wt. of the phage genome was 34 ± 1 × 106. A dual genome population was observed and partial denaturation, duplex and restriction analyses facilitated distinction between constituent phages, α3τ and α3ω. Phage α3τ exhibited a 0.7 ± 0.2 × 106 mol. wt. deletion in its genome with respect to α3ω. Both phages were encapsulated by a headful mechanism and the genomes were permuted over 27% and <;18% of their length respectively. It is concluded that stable variants may be isolated and that these phages offer potential, through physical studies, to elucidate the properties of the Achromobacter-α3 system.", }
