Strain | Initial pH | Final pH | Growth (mg1) | Total ST |
---|---|---|---|---|
MAD002 (wt) | 3.1 | 4.4 | 726.9 A | 29,076 |
7.8 | 8.9 | 747.0 A | 2’530,700 | |
MAD812 (pacC+/209) | 3.1 | 4.0 | 707.3 | 0 |

Cultures were obtained in buffered (100 mM citrate) solid Kafer medium, and growth and ST formation were measured as described in Materials and methods. Statistical analysis of samples (n=5) proceeded by the Tukey test (p=0.05). Statistical significance of the differences in the same experimental block (same strain and medium) were treated as described for Table 1.
