Lignocellulose Saccharification via Cellulose Solvent Based Fractionation Followed by Enzymatic Hydrolysis: the Last Obstacle to Integrated Biorefineries
The production of biofuels and biobased products from low-cost abundant renewable non-food lignocellulosic biomass will be vital to sustainable development because it will bring benefits to the environment, the economy, and the national security. The largest technical and economic challenge for …

Characterization of Cellulase Enzyme Inhibitors Formed During the Chemical Pretreatments of Rice Straw
… the processes of biomass conditioning, enzymatic saccharification, microbial fermentation and ethanol distillation, and one of the major factors affecting its techno-economic feasibility is the biomass recalcitrance to enzymatic saccharification. Preconditioning of lignocellulosic biomass, using …

Forward genetic analysis of cellulose biosynthesis inhibitor resistance and wall hydrolysis sensitivity.
… The ixr and fxr mutants also exhibited enhanced saccharification under enzymatic degradation schemes which is consistent with the observed reduction in cellulose crystallinity. A second forward genetic screen was performed using mild acid hydrolysis to isolate mutants with enhanced …

Optimization of the production of bioethanol from duckweed (Lemna minor)
… optimisation of pretreatments and enzymatic saccharification; finally, fermentation and optimisation of the ethanol yield. Pond-grown L. minor contained 51.2 % carbohydrate (w/w dry matter) of which 77 % (including glucose, galactose and xylose) is fermentable. A series of enzymatic …

Identifying candidate genes/loci influencing barley secondary cell wall properties
… phenolic acid content have been shown to affect saccharification (sugar release from cell walls).<br/><br/>The second generation biofuels are produced from non-food biomass unlike first generation production which uses parts of the plant normally used as food (e.g. grain and corn kernels). This …

Genomic selection for accelerated barley breeding
… breed elite 2-row spring barley for high straw saccharification (digestibility to yield simple sugars).<br/><br/>Aligning with future climate policy, an increase in biofuel production will be useful as we reduce our reliance on fossil-based fuels. Second generation biofuels (produced from …

The exploitation of municipal solid waste (MSW) and related waste paper streams in the production of bioalcohol
… led to its choice as model substrate for study. Saccharification of shredded paper waste was optimised by selection of Accellerase® and additional beta-glucosidase enabling digestion of 99.27% of cellulose. Sequential batch-addition of substrate permitted substrate “concentrations” equivalent to …
