The recalcitrance of cellulosic biomass, the only abundant, sustainable feedstock for making liquid fuels, is a primary obstacle to low cost biological processing, and development of more easily converted plants and more effective enzymes would be of great benefit. Because no single parameter describes recalcitrance, superior variants can only be identified(More)
Since its discovery at the end of the nineteenth century, Moraxella (Branhamella) catarrhalis has undergone several changes of nomenclature and periodic changes in its perceived status as either a commensal or a pathogen. Molecular analysis based on DNA hybridisation or 16S rDNA sequence comparisons has established its phylogenetic position as a member of(More)
BACKGROUND The BioEnergy Science Center (BESC) developed a high-throughput screening method to rapidly identify low-recalcitrance biomass variants. Because the customary separation and analysis of liquid and solids between pretreatment and enzymatic hydrolysis used in conventional analyses is slow, labor-intensive and very difficult to automate, a(More)
Introduction Electronic health record (EHR) technology is available to over half of the nation's eligible professionals participating in the meaningful use program. Now in place, these systems need to be effectively utilized by health care providers and their staff so providers achieve the next step in healthcare transformation by changing clinical care(More)
Pretreatment is a key step in the production of ethanol from cellulosic biomass and is essential to high sugar yields from enzymatic hydrolysis. High temperature water or dilute acid can be employed to primarily solubilize sugars and oligomers from hemicellulose during pretreatment, and cellulase enzymes can access the cellulose left in the pretreated(More)
