Duplicate bottles were used for each dilution series (n = 8). ANCOVA results to test the differences in slope and y intercept among different bacterial groups are as follows. For slope, df = 2, 18 (degree of freedom, residual degree of freedom), F=0.082, and P = 0.921 for experiment 1, and df = 2, 18, F = 0.944, and P = 0.407 for experiment 2. For y intercept, df = 2, 20, F = 4.313, and P < 0.05 for experiment 1, and df = 2, 20, F = 4.543, and P < 0.05 for experiment 2.
