*a*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.
