In a series of linked projects, researchers used the National Science Foundation-supported "Ranger" supercomputer at the Texas Advanced Computing Center and Energy Laboratory's Red Mesa system to simulate the world of enzymes. They explored enzymes from the prodigiously plant-digesting fungus, Trichoderma reesei, and the cellulose-eating bacteria, Clostridium thermocellum. Both of these organisms are effective at converting biomass to energy, though they use different strategies.
