In an enzymatically driven lignocellulosic biorefinery, pretreatment and hydrolysis modules are the two most significant cost contributors for obtaining high gravity sugar solutions. The present study aimed to reduce use of alkali Cellic CTec2 during bioprocessing sugarcane bagasse (SCB). Later its impact on overall process economics environment was evaluated. During pretreatment, solid loading...

Blends of fermentable oligosaccharides in combination with nonfermentable fiber, cellulose, were evaluated for their ability to serve as dietary fibers in dog foods. Using a 6 x 6 Latin square design, 6 diets were evaluated that contained either no supplemental fiber, beet pulp, cellulose, or blends of cellulose, fructooligosaccharides, and yeast cell wall added at 2.5% of the diet. Six ileal-c...

The continued reliance on non-renewable fossil resources has led to serious environmental issues. In light of these concerns, the transition from sources more sustainable ones have been explored, as exemplified by production bio-based lactic acid via lignocellulosic biomass bio-refinery process. Malaysia, second-largest producer palm oil in world, generates abundant, cheap, and underutilized fo...

Compared to traditional lignocellulose biomass, microalgae contain little or no lignin. Traditionally, bioethanol production from undergoes three major steps: (i) pretreatment; (ii) polysaccharides hydrolysis into simple sugars; and (iii) sugar conversion by fermentation. Microalgae convert sunlight, water, CO2 algal biomass. Diatoms, green algae, bluegreen golden algae are four main classes of...

BACKGROUND The expression of biomass-degrading enzymes (such as cellobiohydrolases) in transgenic plants has the potential to reduce the costs of biomass saccharification by providing a source of enzymes to supplement commercial cellulase mixtures. Cellobiohydrolases are the main enzymes in commercial cellulase mixtures. In the present study, a cellobiohydrolase was expressed in transgenic corn...

Addition of glucose-related fermentable sugars or pro,tonophores to derepressed cells of the yeast Saccharomyces ceret'isiae causes a 3to 4-fold activation of the plasma membrane H +-A'fPase within a few minutes. These conditions are known to cause rapid increases in the cAMP level. In yeast strains carrying temperature-sensitive mutations in genes required for cAMP .~jnthesis, incohati~a at th...

Preliminary studies indicate that dietary restriction of fermentable short-chain carbohydrates improves symptoms in irritable bowel syndrome (IBS). Prebiotic fructo-oligosaccharides and galacto-oligosaccharides stimulate colonic bifidobacteria. However, the effect of restricting fermentable short-chain carbohydrates on the gastrointestinal (GI) microbiota has never been examined. This randomize...
