AFEX Pretreatment could reduce cellulosic ethanol cost

A more efficient way of releasing sugars from cellulose could revolutionize cellulosic biofuel production.
MSU-patented process can reduce the cost of making cellulosic biofuels MSU News Michigan State University: "The AFEX (ammonia fiber expansion) pretreatment process, developed by Bruce Dale, University Distinguished Professor of chemical engineering and materials science, uses ammonia to make the breakdown of cellulose and hemicellulose in plants 75 percent more efficient than when conventional enzymes alone are used.The AFEX (ammonia fiber expansion) pretreatment process, developed by Bruce Dale, University Distinguished Professor of chemical engineering and materials science, uses ammonia to make the breakdown of cellulose and hemicellulose in plants 75 percent more efficient than when conventional enzymes alone are used."
