  • a Bold numbers represent a difference of more than ±0.2 for doubling times and more than ±0.1 for OD600s at stationary phase compared to the values for the wild type. Asterisks denote values significantly higher than those of the wild type that exceed the positive thresholds mentioned in the text.
