PH1: An Archaeovirus of Haloarcula hispanica Related to SH1 and HHIV-2
Growth curve of PH1. An early exponential culture of Har. hispanica in 18% (w/v) MGM was infected with virus (MOI, 50), washed to remove unbound virus, and incubated at 37°C. At regular intervals, samples were removed, the absorbance at 550 nm were measured (circles), and the number of infectious centres were determined by plaque assay (squares). Error bars represent one standard deviation of the average titre.
