Chalmers University scientists have confirmed the fact that yeast growth can be facilitated by simple mutations at higher temperatures. This inference can have larger consequences for the production of biofuels and ethanol. The study also made extensive ethanol production easy for Altered Sterol Composition Renders Yeast thermotolerant as well as production of bio-fuels.
They further told that in recent times, during the process of yeast cultivation the vats temperature should be maintained low on scales so that the heat which is produced by them may not destroy the cells. They also suggested the temperature favorable for ethanol production. According to their analysis the temperature should be maintained at 30 degrees Celsius. Moreover raw materials required for the process are gained from starch breakdown process which produces optimum results at 40 degree Celsius.
The research was lead by the professor of systems biology, Jens Nielsen. According to her opinion, to make the yeast thermotolerant the only requirement is a basic mutation. He further explained that ergosterol, which is found in yeast cell membranes if get mutated for–a more “bent” molecule called fecosterol makes the yeast thermotolerant.
