In vivo conversion of 3,4-DHBA into GA or pyrogallol. 3,4-DHBA with a concentration of 1000 mg/L was fed to the culture at 5.5 h. A Strain E. coli BW25113 (Fʹ) with pZE-PobA^** (CTT1) was used. B Strain E. coli BW25113 (Fʹ) with pZE-PobA^*** (CTT2) was used. C Strain E. coli BW25113 (Fʹ) with pZE-PobA^** and pCS-PDC (CTT3) was used. D Strain E. coli BW25113 (Fʹ) with pZE-PobA^*** and pCS-PDC (CTT4) was used
