The wild-type strain Zymomonas mobilis TISTR548 has a critical temperature for its growth and ethanol production at 38 C. To obtain a high potential thermotolerant strain of this ethanologenic bacterium, this wild-type strain was subjected to chemical mutagenesis using ethyl methane sulfonate (EMS)...
