“…Eucalyptus sawdust proved to be an abundant source of carbohydrates (58.8 %), mainly glucan (45.4 %), according to its chemical composition ( Table 1 ). However, a considerable amount of lignin (28.7 %) was also found in the biomass, which corresponds quite well with previously reported data [ 22 , 24 ]. Since this high lignin content may compromise enzymatic hydrolysis efficiency, alkaline pretreatment was carried out in this work to enhance the delignification of biomass.…”

“…However, during the eucalyptus pulp production process, particularly during wood chipping, considerable amounts of solid residues (eucalyptus sawdust) are discarded from the pulping process due to size limitations. Moreover, it has been previously demonstrated by our research group that this material represents an attractive renewable resource in biorefineries for the production of biofuels and value-added platform chemicals [ [22] , [23] , [24] ]. The utilization of eucalyptus sawdust from local pulp industries as a substrate for lactic acid production has not been reported in the literature and is considered an interesting alternative to improve the pulp and paper industry revenues.…”

Highlights Eucalyptus enzymatic hydrolysate contained mixture of glucose and xylose sugars. Carnobacterium sp. produced lactic acid from eucalyptus enzymatic hydrolysate. Glucose was consumed faster and completely rather than xylose during fermentation. Fed-batch fermentation improved lactic acid production and reached 30 g/L.

“…Organosolv processes stand out as promising alternatives for the optimal pretreatment of lignocellulosic materials and have been extensively investigated for biomass valorization (Choi et al, 2019;Tan et al, 2019;Cebreiros et al, 2020). However, pretreatment efficiency may be enhanced by adding scCO 2 in a typical CO 2 -expanded liquid (CXL) scheme.…”

Lignocellulosic biomasses are primarily composed of cellulose, hemicelluloses and lignin and these biopolymers are bonded together in a heterogeneous matrix that is highly recalcitrant to chemical or biological conversion processes. Thus, an efficient pretreatment technique must be selected and applied to this type of biomass in order to facilitate its utilization in biorefineries. Classical pretreatment methods tend to operate under severe conditions, leading to sugar losses by dehydration and to the release of inhibitory compounds such as furfural (2-furaldehyde), 5-hydroxy-2-methylfurfural (5-HMF), and organic acids. By contrast, supercritical fluids can pretreat lignocellulosic materials under relatively mild pretreatment conditions, resulting in high sugar yields, low production of fermentation inhibitors and high susceptibilities to enzymatic hydrolysis while reducing the consumption of chemicals, including solvents, reagents, and catalysts. This work presents a review of biomass pretreatment technologies, aiming to deliver a state-of-art compilation of methods and results with emphasis on supercritical processes.

“…nos materiales lignocelulósicos con potencial en la industria, como las maderas blandas (23-31 %), las maderas duras (20-40 %), la paja (23-38 %), la hoja de tusa del maíz (11-31 %), la corona de piña (14-50 %) y el tallo de maíz (20 %) (Cebreiros et al, 2020). Dicho porcentaje de hemicelulosa convierte al cáñamo en material adecuado para la producción de biocombustibles y otros productos derivados del azúcar, tales como bioetanol, biobutanol, furfural y xilital, entre otros (Cebreiros et al, 2020), o como materia prima para la producción de azúcares reductores (Dávila et al, 2017).…”

El desarrollo y la investigación de nuevos productos que puedan sustituir parcial o completamente materias primas empleadas para la producción de energía, productos químicos de alto valor añadido e incluso la fabricación de papel, ha permitido que el cáñamo industrial (Cannabis sativa L.) se vuelva atractivo como principal materia prima en la reactivación de una economía de base biológica con altas condiciones y capacidades de producción. A partir de lo anterior, el objetivo de este trabajo investigativo es profundizar sobre el potencial del uso de fibra de cáñamo en la industria del papel, soportado por estudios realizados por el Estado Colombiano en lo referente a las disponibilidad de cultivos forestales con fines comercialesque inicialmente se destinan para la siembra y producción de recursos madereros como el pino y eucalipto. Se ha considerado de importancia demostrar que el cáñamo, como fuente de producción primaria, brinda ventajas competitivas económicas, ambientales y sociales frente a los cultivos tradicionales, incluso para las nuevas fuentes de investigación de base biológica.
