Pretreatment of sweet sorghum bagasse at 100°C at three lime doses (g per g bagasse), 0, 0.05, and 0.1; two water contents (ml per g bagasse), 7 or 10; and two treatment durations (h), 1 or 2 were evaluated. Composition analysis of pretreated samples revealed that the higher the lime dose, the...

Kenaf (Hibiscus cannabinus) has received considerable attention as a renewable resource because of its fast growth and low lignin content. In the present study, a combination pretreatment of kenaf core using electron beam irradiation (EBI) and dilute alkali was investigated to improve the sugar...

This study deals with the development of an eco-friendly hydrothermal pretreatment of wheat straw. This pretreatment involves moderate temperatures without generation of liquid fractions allowing to reduce the energy input consumption and the environmental impact and enhance the enzymatic...

Different response between woody core and bark of goat willow biomass to concentrated phosphoric acid pretreatment prior to enzymatic saccharification was investigated as changes of chemical compositions, carbohydrate compositions, and crystallinity of cellulose before and after pretreatment....

This study carried out an exergetic analysis of a proposed ethanol production scheme in which a new process – enzymatic hydrolysis of sugarcane bagasse – is integrated into the conventional process. Seven cases were evaluated, among them a conventional ethanol production plant without...

Cellulosic ethanol made from cellulosic biomass is a promising alternative to petroleum-based transportation fuels. Enzymatic hydrolysis is a crucial step in cellulosic ethanol production. In order to better understand the mechanisms of enzymatic hydrolysis, relationships between cellulosic...

Two different sugar yield definitions (cellulose-based and biomass-based) were used in reported studies investigating the relationship between biomass particle size and enzymatic hydrolysis sugar yield. It is noticed that these reported relationships are not consistent if sugar yield is defined...

In this study, the effects of enzymatic hydrolysis on lipid extraction from microalga (Chlorella vulgaris) were investigated prior to biodiesel production. The initial fatty acids content of C. vulgaris was 87.6 mg/g cell. The microalgal cell walls were hydrolyzed by cellulases and then their...

Floating residue (FR), a surplus by-product from the alginate extraction process, contains large amount of cellulosic materials. The technical feasibility of FR utilization as a resource of renewable energy was investigated in this paper. The production of yeast-fermentable sugars (glucose) from...
