a
Compositions of the media are described in the text.
b
Average OD600 (two tubes) for two repetitions with initial bacterial concentrations ranging from 1 to 106 CFU/ml. The residual standard errors were 0.1509 and 0.1013 for the samples that were shaken and not shaken, respectively, while the P value was 0.0001 in both cases. Means followed by the same letter are not statistically different as determined by the Duncan method.
