a
Mean values and standard deviations were calculated from two replicates, except for strains L1528, BC187, NCYC 361, U227, and ECA5, for which only one experiment was conducted (and therefore data for these strains do not include standard deviations).
b
Adjusted R2 value.
c
**, significant at P < 0.01; ***, significant at P < 0.001.
