Genetically engineered bug could produce cheap biofuel

This new finding describes how these new genetically engineered bugs could produce biofuel at higher temperatures and cheaper than previous methods. The bugs can operate at temperatures around 122 degrees F, rather than previous ones which topped out at 98.6 degrees F. This allows scientists to decrease the amount of the expensive enzyme used by 2.5 times. The production methods used by scientists also rely on switch grass and cornstalks, rather than using eatable food crops.
