a
Mean percentages of calculated Vβ-galmax or KAA with AA as the only source. See the legend to Fig. 1 for the procedure and text for the description of parameters (three to six tests). PB was enriched with different carbon/nitrogen sources in the presence of growing concentrations of amino acids (0, 10, 30, and 150 μM).
