Various engineered strains and their traits. A Schematic diagram of the engineering for introducing sucrose metabolic pathways. B Maximum OD, sugar consumption and ethanol production for different engineered strains under 20 g/L sucrose in 30 h. C Enzyme activity test with the cell lysis buffer, or with the liquid supernatant of cell culture medium without cell lysis (marked with “*”). Presented data are derived from three independent experiments
