Effects of pretreatment applied to sugarcane bagasse on composition and morphology of cellulosic fractions
(2019-07-01)
Due to the growing demand for renewable energy, the energy based on biomass plays an important role in energy policies of countries all over the world. Seven different pretreatments were performed on SCB to obtain yields, ...
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, ...
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 ...
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 ...
Nuclear magnetic resonance investigation of water accessibility in cellulose of pretreated sugarcane bagasse
(BioMed Central, 2014)
Abstract
Background
Enzymatic hydrolysis is a crucial step of biomass conversion into biofuels and different pretreatments have been proposed to improve the process efficiency. ...
Nuclear magnetic resonance investigation of water accessibility in cellulose of pretreated sugarcane bagasse
(BioMed CentralLondon, 2014-09)
Background: Enzymatic hydrolysis is a crucial step of biomass conversion into biofuels and different pretreatments have been proposed to improve the process efficiency. Amongst the various factors affecting hydrolysis ...
Enzymatic Hydrolysis of Chemithermomechanically Pretreated Sugarcane Bagasse and Samples with Reduced Initial Lignin Content
(WILEY-BLACKWELL, 2011)
Chemithermomechanical (CTM) processing was used to pretreat sugarcane bagasse with the aim of increasing cell wall accessibility to hydrolytic enzymes. Yields of the pretreated samples were in the range of 75-94%. Disk ...
Microscopic and Biochemical Analysis to Better Understand the Impact of Alkaline Pretreatments on Lignocellulosic Biomass
(Florianópolis, SC., 2021-05-14)
Due to an increased demand for more sustainable energy sources, Anaerobic Digestion (AD) of solid organic wastes such as biomass and energy crops have been gaining attention. In this study, varieties of sorghum and miscanthus ...
Bidimensional modeling applied to oil extraction kinetics of microwave-pretreated canola seeds
(Elsevier, 2017-01)
The effect of microwaves on canola oil extraction kinetics and on tocopherol and canolol content in oil was studied. Oil was extracted with hexane at constant temperature (298–333 K) at different times (300–64800 s). In ...
Evaluation of a simple alkaline pretreatment for screening of sugarcane hybrids according to their in vitro digestibility
(Elsevier B.V., 2013-11-01)
Lignin depletion in new cultivars or transgenic plants has been identified as a way to diminish the recalcitrance of lignocellulosic materials. Direct enzymatic digestion of these materials provides some discrimination ...
