From: Evaluation of the application potential of Bdellovibrio sp. YBD-1 isolated from Yak faeces
(A) The effect of pH on the and lytic activity of YBD-1 indicated by changes in OD600 in the broth co-cultures(30 ℃, pH 7.0 for 96 h). pH range was tested at 5.0, 5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, and 9.0. (B) Number of E.coli prey cells(log10CFU/ml) with/ without YBD-1 for pH5.0,7.0,9.0 at 48 h. All experiments were conducted three times independently. Statistical analysis was performed using two-way ANOVA. The amount of asterisks(*) obtained from SPSS is directly related to statistical significance(***: p < 0.001).
