Low moisture anhydrous ammonia pretreatment of four lignocellulosic materials—distillers dried grains with solubles, corn gluten feed, corn fiber, and oil palm frond

Lignin and hemicellulose structures in cellulosic materials serve as a barrier for enzyme reactions. A pretreatment step is often needed to break these components to allow the biomass to be utilized as a source of value-added products. Various available pretreatment methods possess common drawbacks...
