  1. *his strain was a control. During fermentation, 1 mM IPTG was added to the fermentation medium to induce the expression of catechol 1,2-dioxygenase. Errors (standard deviations) were calculated based on at least three independent experiments.
  2. **Yield: produced ccMA against consumed glucose.
