Ozonolysis combined with ultrasound as a pretreatment of sugarcane bagasse: Effect on the enzymatic saccharification and the physical and chemical characteristics of the substrate
(2016-10-01)
Sugarcane bagasse (SCB) was treated in three stages using ozone oxidation (O), washing in an alkaline medium (B) and ultrasonic irradiation (U). The impact of each pretreatment stage on the physical structure of the SCB ...
Hydrodynamic cavitation for lignocellulosic biomass pretreatment: a review of recent developments and future perspectives
(2022-12-01)
The hydrodynamic cavitation comes out as a promising route to lignocellulosic biomass pretreatment releasing huge amounts of energy and inducing physical and chemical transformations, which favor lignin–carbohydrate matrix ...
Minimum Lignin and Xylan Removal to Improve Cellulose Accessibility
(2020-09-01)
The lignocellulosic biomass, such as provided by the sugarcane, is an abundant source of raw materials for energy production. Milling and pretreatments can be employed to alter the structure of the materials, remove lignin, ...
Effect of chemical pretreatment on the physical properties of dehydrated grapes
(Marcel Dekker Inc, 1999-01-01)
The effects of chemical pretreatment and air drying temperature on drying kinetics, shrinkage, density and rehydration ratio of grapes were determined at various moisture contents. It was observed that the chemical ...

(Marcel Dekker Inc, 1999-01-01)
The effects of chemical pretreatment and air drying temperature on drying kinetics, shrinkage, density and rehydration ratio of grapes were determined at various moisture contents. It was observed that the chemical ...
Effect of pretreatment and enzymatic hydrolysis on the physical-chemical composition and morphologic structure of sugarcane bagasse and sugarcane straw
(2016-11-01)
The present work aimed to study the effect of the pretreatment of sugarcane bagasse and straw with microwave irradiation in aqueous and acid glycerol solutions on their chemical composition, fiber structure and the efficiency ...
Characterization of the pre-treated biomass of Eichhornia crassipes (water hyacinth) for the second generation ethanol production
(2017-09-22)
Eichhornia crassipes (water hyacinth), is considered an aquatic pest. An alternative to solve the excess water hyacinth problem is to use the biomass for second generation ethanol. This process can be divided into: collection ...
Effect of Dilute Acid Pretreatment on the Sugarcane Leaf for Fermentable Sugars Production
(2022-01-01)
Bioethanol can be produced from lignocellulosic material, however, due to the material recalcitrance, a pretreatment step is needed to improve cellulose accessibility. Dilute acid pretreatment improves the cellulose ...
Characterization of anatomy, lignin distribution, and response to pretreatments of sugarcane culm node and internode
(2016-06-01)
Sugarcane culm has different types of tissue organization, and its heterogeneity can influence the bagasse quality generated in the sugar/ethanol industry. The heterogeneity of the sugarcane bagasse contributes to the ...
