[2] It was first isolated in 1966 from a sample taken from the aeration tank at a sewage plant in East Lansing, Michigan.

[citation needed] Sedimentation analysis indicates that gh-1 carries its genetic payload in the form of a 37,359 bp linear strand of dsDNA,[3][4] inside an icosahedronal capsid 50 nm in diameter.

[1] One-step growth experiments indicate that the latent period is approximately 21 min, with a burst size of 103.

[1] It has been shown that this phage group requires an intact O-antigen on its host's outer membrane in order to successfully replicate and it is thus likely that lipopolysaccharide acts as the phage receptor.
