Advancing characterization techniques for structure-property determination of in-situ lignocelluloses
… DMA while analyzing various solvent-plasticized lignocelluloses. The rheology of wood in various organic solvents is studied through dynamic thermal scans, Time/temperature superposition (TTS) and fragility analysis. Plasticizing solvents and wood grain orientation significantly affected the …

Evaluation of Stability Parameters for Landfills
… of this study was to evaluate the importance of lignocelluloses in biodegradation and the secondary settlement based on dry density and typical landfill evaluating parameters. Both parts of the study samples were collected and analyzed from eleven landfills. In the first part of the study, …

Design of a Saccharomyces cerevisiae strain capable of simultaneously utilizing cellobiose and xylose
… microorganism for bioethanol production from lignocelluloses. However, glucose repression limits efficient ethanol production because glucose in lignocellulosic hydrolysates inhibits xylose and other sugars’ utilization. As a result, it is attractive to construct a glucose derepressed S. …

Production of lactic acid by microbial fermentation of hemicellulose sugars
… from starchy materials. Converting pentoses from lignocelluloses into lactic acid by lactobacillus has received much attention in recent years. The feasibility of improving lactic acid production from pentoses by using Lactobacillus pentosus (ATCC 8041) which is a facultative heterofermentative …

Lignocellulose Saccharification via Cellulose Solvent Based Fractionation Followed by Enzymatic Hydrolysis: the Last Obstacle to Integrated Biorefineries
… biomass. Cellulose- and organic-solvent-based lignocelluloses fractionation (COSLIF) technology was employed to overcome biomass recalcitrance. Surface response methodology (SRM) showed that optimal COSLIF pretreatment conditions were 85% (w/v) H₃PO₄ and ~50 °C, regardless of moisture contents …

Biomass pretreatment toward efficient hydrolysis for sustainable biofuel applications
… their potential as pretreatment agents for lignocelluloses (Chapter 4). 1-Methylimidazole (MI), a precursor to some ILs, has been determined to be the most promising agent for lignocellulose pretreatment due to its exceptional delignification and cellulose expansion efficiency. The chemical …
