FIG 1.

Identification of phage Bp7 receptors. (A) Adsorption kinetics of Bp7 to E. coli K-12. The adsorption rate of Bp7 to E. coli K-12 at different times was tested by the plaque assay and is shown as residual PFU percentages in the supernatant. (B) Effects of the different treatments of E. coli K-12 on phage Bp7 adsorption. E. coli K-12 was treated by ProtK or sodium acetate containing IO₄⁻, and the adsorption effects of phage Bp7 on E. coli K-12 are shown as residual PFU percentages in the supernatant. All assays were performed in triplicate. **, P < 0.01.
