Unfortunately, these particular enzymes don't work fast enough to break down cellulose at a pace (and price) that is competitive with fossil fuels yet. So, computational scientists at NREL set about trying to understand and create enhanced, designer enzymes to speed up biofuel production and lower the cost of biomass-derived fuel to serve the global population.
"It's a Goldilocks problem," Beckham said. "The enzymes have to be 'just right,' and we're trying to find out what just right is, why, and how to make mutations to the enzymes to make them most efficient.
