Alkaline Pretreatment of Coastal Bermudagrass for Bioethanol Production

Lignocellulosic materials are regarded as an alternative energy source for bioethanol production to reduce our reliance on fossil fuels. Pretreatment is important for improving the enzymatic

High Temperature Dilute Acid Pretreatment of Coastal Bermudagrass

The conversion of lignocellulosic biomass into ethanol is an encouraging technology in the face of concerns over global warming and finite energy resources. In the southeastern United States, coastal

Conversion of Bamboo to Sugars by Dilute Acid and Enzymatic Hydrolysis

Lignocellulosic biomass is an important alternative energy source to be utilized for ethanol production. In this work, bamboo (Dendrocalamus asper Backer) was used as biomass feedstock for conversion

Lime Pretreatment of Coastal Bermudagrass for Bioethanol Production

Coastal bermudagrass (CBG) is regarded as a potential lignocellulosic feedstock for bioethanol production in the southeast United States. Lime pretreatment of CBG for enhanced reducing sugar recovery

Effect of Lignocellulosic Substrate and Commercial Cellulase Loading on Reducing Sugar Concentration for Ethanol Production

Fuel ethanol production from lignocellulosic biomass requires a relatively high initial sugar concentration in hydrolysate. Raising the substrate and enzyme concentration in the batch hydrolysis will

Comparison of different chemical pretreatments for their effects on fermentable sugar production from miscanthus biomass

Pretreatment is extremely required in lignocellulosic bioethanol production to improve enzymatic digestibility of biomass by disrupting lignin structure, reducing cellulose crystallinity, and


This study was conducted to produce xylose by acid hydrolysis from lignocellulose by product . The process of acid hydrolysis carried out using dilute H2SO4 to hydrolyze the available sources of

High temperature dilute acid pretreatment of coastal Bermuda grass for enzymatic hydrolysis.




Hybrid process for the conversion of lignocellulosic materials

The best residues for enzymatic hydrolysis and simultaneous saccharification and fermentations (SSF) came from the higher temperature pretreatment with the Parr reactor, however, a large portion of the xylose fraction was degradation to furfural and glucose was degraded to HMF.

Dilute-Acid Pretreatment of Corn Residues and Short-Rotation Woody Crops

As a prerequisite for the enzymatic saccharification or simultaneous saccharification and fermentation process for ethanol synthesis, a dilute-acid pretreatment of the biomass has been shown to be a

Pretreatment of wheat straw using combined wet oxidation and alkaline hydrolysis resulting in convertible cellulose and hemicellulose

The wet oxidation process of wheat straw has been studied as a pretreatment method to attain its main goal: to break down cellulose to glucose enzymatic, and secondly, to dissolve hemicellulose without producing microbial inhibitors.

Dilute acid pretreatment of short rotation woody and herbaceous crops

Large-scale production of ethanol or other transportation fuels by biological conversion of lignocellulosic biomass will eventually require integration with large-scale production of biomass

Pretreatment and enzymatic saccharification of corn fiber

A method for pretreatment and enzymatic saccharification of corn fiber is presented and the yield of monomeric sugars from corn fiber was typically 85–100% of the theoretical yield.

Optimization of steam explosion as a method for increasing susceptibility of sugarcane bagasse to enzymatic saccharification

The technique of autohydrolysis steam explosion was examined as a means for pretreatment of sugarcane bagasse to achieve high total sugar yield with moderate enzyme requirement and only minor losses due to sugar decomposition.

Two-temperature dilute-acid prehydrolysis of hardwood xylan using a percolation process

A novel two-temperature dilute-acid prehydrolysis of hybrid poplar xylan that exploits the xylan biphasic kinetics at moderate temperatures is described, resulting in improvements in both yield of xylose equivalents and ethanol production level and rate.

Two-stage dilute-acid pretreatment of softwoods

Simultaneous saccharification and fermentation using an adapted Saccharomyces cerevisiae yeast strain further improved cellulose conversion yield and lowered the enzyme requirement.
