From: Ethanol tolerance in engineered strains of Clostridium thermocellum
Adaptation of strains to added ethanol. Growth rate was measured in a 96-well plate with various concentrations of added ethanol in MTC-5 medium with 5 g/L cellobiose. For strains LL1790, LL1791, LL1792, and LL1805, the parent strain is LL1592. In strain LL1592, a targeted deletion of the C. thermocellum adhE resulted in strain LL1590. Error bars represent one standard deviation with 2–5 biological replicates. Traces are slightly offset along the x-axis to more clearly show error bars
