Phage replication of SPβ WT, ΔaimR, and ΔaimR complemented
(A) Strains Δ6 lysogenic for phages SPβ WT, ΔaimR, and ΔaimR complemented with aimRSPβ were MC induced (0.5 μg/mL), and 1 mL of each culture at different time points after induction was collected. Samples were loaded in a 0.7% agarose gel, Southern blotted, and probed for phage DNA.
(B) Strains 168 lysogenic for phages SPβ WT, ΔaimR, and ΔaimR complemented with aimRSPβ were MC induced (0.5 μg/mL), and 5 mL of each culture at different time points after induction was collected. Samples were loaded in a 0.7% agarose gel, Southern blotted, and probed for phage SPβ DNA.
