  • a By using indicator strips, the pH was monitored in competition cultures between DS17 (uvrY) and DS17 wild-type strains grown in minimal medium and in two different Kornberg media supplemented with the indicated carbon sources.

  • b The pH with 0.5% glucose (+Glucose) and the pH without glucose (−Glucose) are shown.
