Overlay assay
WebPhage activity was tested by a double overlay agar plaque assay . The clear plaque was picked with a pipette tip, and phages were suspended in TM buffer (50 mM Tris-HCl, 10 mM MgSO 4 at pH 7.5). Isolated phages were purified through a triple transfer of single plaque and propagated until homologous plaques were obtained. Weband overlay media (at pH 7.5) was added. Infected cells were incubated at 37 °C in CO 2 atmosphere at either 4 or 4.5%.
