Fig. 3From: Detection of viable but non cultivable Escherichia coli after UV irradiation using a lytic Qβ phageQβ phage titers dependence on host UV irradiation state after 18 h of incubation at 37°C. P 0 is the initiated free-phage concentration at time zero (t 0 ), P′ is the Qβ phage titers after 18 h of incubation at 37°C in the presence of irradiated Escherichia coli by increased UV dose (0, 45, 60, 90, and 120 mJ/cm2)Back to article page
