A combination of steam explosion (SE) and alkaline peroxide (AP) used to pretreat bamboo was investigated. Steam explosion at 224 °C for 4 min was applied to bamboo, and the pretreated bamboo was delignified by alkaline peroxide. Enzymatic hydrolysis was compared in the pretreated samples. Steam pretreatment led to remarkable hemicellulose solubilization (63.2%). Lignin solubilization (93.1%) w...

BACKGROUND Rice straw has considerable potential as a raw material for bioethanol production. Popping pretreatment of rice straw prior to downstream enzymatic hydrolysis and fermentation was found to increase cellulose to glucose conversion efficiency. The aim of this study was to investigate the influence of popping pretreatment and determine the optimal enzyme loading using a surface response...

Production of bioethanol from agricultural residues and hays (wheat, barley, and triticale straws, and barley, triticale, pearl millet, and sweet sorghum hays) through a series of chemical pretreatment, enzymatic hydrolysis, and fermentation processes was investigated in this study. Composition analysis suggested that the agricultural straws and hays studied contained approximately 28.62-38.58%...

BACKGROUND When producing biofuels from dedicated feedstock, agronomic factors such as harvest time and location can impact the downstream production. Thus, this paper studies the effectiveness of ammonia fibre expansion (AFEX) pretreatment on two harvest times (July and October) and ecotypes/locations (Cave-in-Rock (CIR) harvested in Michigan and Alamo harvested in Alabama) for switchgrass (Pa...

The present study reports a factorial greenhouse experiment usinga randomized completeblock design in 2014 which investigated the effects of salt-pretreatedGlomus fasciculatumfungus, salinity, and the interaction effect of these variables on thephysiological properties ofbarley. The first factor was mycorrhizasalinity pretreated with different levels of salt (0, 25, 50and100mM) and the second f...

In this study an attempt was made to investigate bio pretreatment and chemical process observe the effects in terms of absorbency, bursting strength, wash rubbing fastness, water, energy consumption. Four samples (S1, S2, S3 S4) were prepared by different processes then dyed with two reactive dyes. When compared chemically fabrics, biopretreated fabrics demonstrated improved abrasion resistance...

Pretreatment is among the most costly steps in the overall biological conversion of cellulosic biomass to fuels and chemicals. Pretreatment also has a profound effect on all other operations from choice and preparation of feedstock all the way to final product recovery and use of process residues. Yet, because cellulosic biomass is naturally resistant to breakdown to release the sugars containe...

Introduction The necessary biomass pretreatment step, to render the material accessible to the relevant enzyme pool, has been under thorough investigation as the production of biomass syrups, via enzymatic hydrolysis, with high sugars concentrations and yields and low inhibitors concentrations requires the pretreatment to be both efficient and low cost. A good choice for biomass pretreatment sh...
