New Ethanol Study Findings Have Been Reported from North Carolina State University

June 10, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Ethanol. According to news reporting from Raleigh, North Carolina, by NewsRx journalists, research stated, "The amount of residual lignin and hemicelluloses in softwood fibers was systematically varied by SO2-ethanol-water fractionation for integrated biorefinery with nanomaterial and biofuel production. On the basis of their low energy demand in mechanical processing, the fibers were deconstructed to lignocellulose nanofibrils (LCNF) and used as substrate for bioconversion."

The news correspondents obtained a quote from the research from North Carolina State University, "The effect of LCNF composition on saccharification via multicomponent enzymes was investigated at different loadings. LCNF digestibility was compared with the enzyme activity measured with a quartz crystal microbalance. LCNF hydrolysis rate gradually decreased with lignin and hemicellulose concentration, both of which limited enzyme accessibility. Enzyme inhibition resulted from non-productive binding of proteins onto lignin. Near complete LCNF hydrolysis was achieved, even at high lignin and hemicellulose content."

According to the news reporters, the research concluded: "Sugar yields for LCNF were higher than those for precursor SEW fibers, highlighting the benefits of high surface area in LCNF."
