(A) The flow chart shows the mutant development process from the initial WT strain through the final mutant. Single colony isolate 6 was chosen as the final 17.5% v/v Populus hydrolysate tolerant mutant strain (PM). (B) Initial growth of WT culture on various concentrations of Populus hydrolysate to determine inhibitory effect. The culture in 5% v/v Populus hydrolysate started growing late in the fermentation. (C) An example of serial transfers showing increased growth over time in 10% v/v Populus hydrolysate. Illustrative curves show each daily serial transfer.
