Two-stage alkaline and acid pretreatment applied to sugarcane bagasse to enrich the cellulosic fraction and improve enzymatic digestibility
(2020-01-01)
Sugarcane bagasse (SB) is made up of cellulose (32-43%), hemicellulose (19-34%) and lignin (14-30%). Due to high recalcitrant nature of SB, pretreatment is required to deconstruct its structure and enrich the cellulosic ...
Borage (Borago officinalis L.) response to salinity at early growth stages as influenced by seed pre-treatment
(2021-07-01)
Knowledge of plant response to salinity, especially at early growth stages, is critical to optimizing crop production in salt-affected soils. In this paper we explore quantitatively the effectiveness of seed pre-treatment ...
Optimization of the pretreatment of Prosopis nigra sawdust for the production of fermentable sugars
(North Carolina State University. Departament of Wood & Paper Science, 2013-01)
The black carob tree (Prosopis nigra) is a particularly valued species in Chaco, Argentina on account of its hard wood. Finding a use for the sawdust, the main industrial residue of wood, could be useful within the furniture ...
Assessment of non-conventional pretreatments for agriculture wastes utilization
(2015)
Los pretratamientos convencionales de biomasa lignocelulósica involucran el uso intensivo de altas temperaturas, presiones, largos tiempos de residencia sumado a los requerimientos de productos químicos y los elevados ...
Supercritical CO2 processing of pretreated rosehip seeds: effect of process scale on oil extraction kinetics
(ELSEVIER SCIENCE BV, 2004)
Rosehip oil was extracted from milled seeds with supercritical carbon dioxide (SC-CO2). The effects of sample pretreatment and interstitial solvent velocity (0.40-2.45 mm/s) on kinetics of extraction (oil yield versus time) ...
An integrated approach to obtain xylo-oligosaccharides from sugarcane straw: From lab to pilot scale
(2020-10-01)
Sugarcane straw (SS) is a widely available agricultural processing feedstock with the potential to produce 2nd generation bioethanol and bioproducts, in addition to the more conventional use for heat and/or electrical power ...
Pré-tratamento alcalino (NaOH) do bagaço de cana-de açúcar para a produção de etanol e obtenção de xilooligômeros
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2011-03-28)
The aim of this study was to optimize the pretreatment of sugarcane bagasse raw and exploded with diluted sulfuric acid, water and sodium hydroxide in order to obtain Xylooligosaccharides in hemicellulose and production ...
