Fig. 2From: Enhanced ethanol formation by Clostridium thermocellum via pyruvate decarboxylaseThermostability of eight pyruvate decarboxylase candidates. Enzyme activity at 30 °C is set to 100%. Thermostability was tested at the temperatures of 45, 50, 55 and 60 °C. The data represents the average of three individual rounds of protein purification and assay. Error bars are smaller than the size of the data point markers and are therefore not shownBack to article page
