Hydroxytyrosol production of chromosome engineered strain GsBR5. Hydroxytyrosol production of recombinant GsBR5 transformed with pBbE1k-3 and pBbS1a-3. The recombinant cell, treated at different IPTG concentration to induce target protein production, was cultured up to 96 h at 30 °C. Data are presented as mean values with standard deviations for three independent experiments. Symbols without an error bar indicate that they are larger than the size of the error bar
