“…Some studies have applied wet oxidation pretreatment to break up the crystalline superstructure of EB and allow easier access of holocellulose by microbes 48,49 . Lee et al 48 used oxygen concentrations of 3%–9% for 45 min and 180°C, and the pretreated EB was digested in anaerobic conditions, increasing methane yield by 43%.…”

Lee et al 49 extend the scope of their previous work, including clarified manure in EB, which resulted in a 49% increase in methane production compared to the control.…”

“…El contenido de hemicelulosa fue inferior al 20 % en el escobajo (16,55 ± 0,10 %). Estos resultados coinciden con lo encontrado en la literatura por Talero et al (2019), pero difiere en la fibra del fruto (19,38 ± 0,04 %) con valores superiores descritos en la literatura (Lee et al, 2020;Saadiah Hafid et al, 2021). Al ser un residuo no celulósico, debe aplicarse tratamientos como el peróxido alcalino para la separación de la celulosa antes de ser utilizados.…”

Introducción. La palma aceitera (Elaeis guineensis Jacq.) en la Amazonia peruana tiene un área instalada en producción de 72 861 ha, cuyo procesamiento del fruto genera residuos sólidos como el escobajo y el mesocarpio secos. Objetivo. Determinar las características fisicoquímicas de la biomasa residual, escobajo y fibra del fruto, de la extracción de aceite de palma en la Amazonia peruana, para su potencial uso en la elaboración de materiales biodegradables. Materiales y métodos. Durante agosto a octubre del 2020, se recolectaron 19,39 t/día de escobajo y 13,05 t/día de fibra del fruto de la palma aceitera en Pucallpa, Distrito de Neshuya, Perú. Los análisis de solubilidad en agua caliente y humedad se determinaron mediante la prueba estándar americana (American Society for Testing and Materials). La solubilidad en soda, se obtuvo mediante el estándar de Technical Association of the Pulp and Paper Industry. Para la determinación de la celulosa, hemicelulosa y lignina, se empleó la cromatografía líquida de alta resolución (HPLC) y detector de índice de refracción (RI). Resultados. Las propiedades físicas de humedad (%) y solubilidad en soda (%) no presentaron diferencias entre el escobajo y la fibra. El escobajo y la fibra presentaron solubilidad en agua caliente con valores inferiores al 17 %. Las propiedades químicas en la fibra fueron mayores que en el escobajo, en base al porcentaje de celulosa, hemicelulosa y lignina. Conclusiones. Los resultados físicos y químicos del escobajo y de la fibra del fruto de palma aceitera, permitirían el desarrollo de procesos tecnológicos adecuados para su conversión a productos biológicos.

“…Novel and updated pretreatment methods for lignocellulose include CO 2 explosion pretreatment, SO 2 explosion pretreatment, N 2 explosion pretreatment, supercritical fluid pretreatment, and wet oxidation and hydrogen peroxide-acetic acid pretreatment ( Wi et al, 2015 ; Lee et al, 2020 ; Arumugham et al, 2022 ). However, ongoing efforts to apply these methods have not yet resulted in economically viable industrial processes.…”

For decades, lignocellulosic biomass has been introduced to the public as the most important raw material for the environmentally and economically sustainable production of high-valued bioproducts by microorganisms. However, due to the strong recalcitrant structure, the lignocellulosic materials have major limitations to obtain fermentable sugars for transformation into value-added products, e.g., bioethanol, biobutanol, biohydrogen, etc. In this review, we analyzed the recent trends in bioenergy production from pretreated lignocellulose, with special attention to the new strategies for overcoming pretreatment barriers. In addition, persistent challenges in developing for low-cost advanced processing technologies are also pointed out, illustrating new approaches to addressing the global energy crisis and climate change caused by the use of fossil fuels. The insights given in this study will enable a better understanding of current processes and facilitate further development on lignocellulosic bioenergy production.
