Gene For Zipped Lignin Production In Plants

IntroductionLignin, an abundant polymer of vascular plants that provides structural integrity and resistance to chemical and enzymatic damage to the plant cell wall, is the second most abundant polymer on earth and critical to the strength and survival of terrestrial plants. Unfortunately, its mechanical strength and resistance to chemical degradation,...

Using Ammonia Treatment to Make Biomass Pellets

IntroductionCellulosic biomass is not dense enough to be transported economically over long distances. The treated biomass must be compressed to increase its density. However, when compressed, the biomass tends not to bind sufficiently. Additionally, current additives used to increase binding characteristics of the biomass are expensive. Description...

Lignocellulosic Biomass Pretreatment Using Gaseous Ammonia and Combinations with Hot Inert-Carrier Gases (AFEX)

IntroductionTo achieve high yields of glucose and other products for use in biofuels and bio-based chemicals, lignocellulose must first be pretreated. The goal of pretreatment is to decrease the crystallinity of cellulose, increase the biomass surface area, remove hemicellulose, and break the lignin seal. Current pretreatments use liquid ammonia, dilute...

Utility Promoters for Biomass Feedstock Biotechnology

IntroductionGenetic optimization of biomass is necessary to improve the rates and final yields of sugar release from woody biomass. Areas that would benefit from genetic optimization include growth rate, environmental stress tolerance, yields of easily fermentable polysaccharides, total lignin content, lowering biomass recalcitrance to fermentation,...
