| Discovery Notes | Isolation by Dominic Garza and Michelle Zorawik.
An enriched culture was prepared by combining 15 mL of soil with 25 mL of PYCA broth. The bacterial strains of A. sp., A. globiformis, A. sulfureus and A. atrocyaneus were then added in equal concentrations. The enriched culture was incubated at 30℃ for 48 hours with shaking. After filtering with a 0.22 µm filter, the sample was plated on PYCA plates with 2X PYCa soft agar using the standard pour plate method.

| Sequencing Facility | Pittsburgh Bacteriophage Institute |
| Shotgun Sequencing Method | Illumina Sequencing |
| Approximate Shotgun Coverage | 293 |
| Genome length (bp) | 62027 |
| Character of genome ends | Direct Terminal Repeat |
| Direct Terminal Repeat Length | 1042 bp |
| End Determination Notes | As this was the first phage of its (close) kind, we looked closely at the ends. There was a clear region of about 1 kb that had ~2x the coverage level of the rest of the genome. This implies a direct terminal repeat. The right end of this terminal repeat was well-defined in the sequencing reads, with many read starts appearing at a particular base. The left end was less well-defined, however, and so we chose a base near the left end of the double-coverage region that had slightly more read starts than the surrounding area. |
