Lignocellulosic biomass, for its large quantities and relatively low cost, is regarded as a potential renewable energy resource for cost-effective ethanol production.1 Wheat straw is one of the most abundant crop residues in European countries with a production of 170 million tonnes per year, and it seems to be one of the cheapest and the most useful raw material for ethanol production.2 Wheat ...

Background With growing concern in obtaining clean and renewable energy, many works in bioenergy has been developed in order to obtain substantial gains for the environment. Due to the large environmental impact associated to the use of fossil fuels, ethanol production from lignocellulosic materia lhas been widely explored, aiming environmental, economic and social benefits. Lignocellulosic bio...

Use of ethanol as a substitute for gasoline may be an effective measure to reduce petroleum consumption and mitigate global warming. Ethanol is already used as an additive or total substitute for gasoline worldwide. In particular, quite large amounts of ethanol for fuel use are produced from corn in the USA and from sugarcane in Brazil. However, those crops are also cultivated for food consumpt...

Bamboo is a potential lignocellulosic biomass for the production of bioethanol because of its high cellulose and hemicelluloses content. In this research, ethanol organosolv pretreatment with dilute sulfuric acid as the catalyst was studied in order to enhance enzymatic saccharification of moso bamboo. The addition of 2% (w/w bamboo) dilute sulfuric acid in 75% ethanol had a particularly strong...

Agave americana is one of commonly grown agave species but currently less valuable because its large flower stalk cannot be used for producing alcoholic beverage. In the present study, the stalk was pretreated with dilute acid (DA), sulfite (SPORL), and sodium hydroxide (NaOH) to preliminarily assess its potential as feedstock for bioethanol production. The changes of cell wall components durin...

UNLABELLED BACKGROUND Previous research on alkaline pretreatment has mainly focused on optimization of the process parameters to improve substrate digestibility. To achieve satisfactory sugar yield, extremely high chemical loading and enzyme dosages were typically used. Relatively little attention has been paid to reduction of chemical consumption and process waste management, which has prov...
