“…Bamboo is one of the fastest growing woody plant biomasses, and it contains 57 to 65 wt% cellulose, 27 to 30 wt% hemicellulose, and 4.9 to 5.0 wt% lignin (Shimokawa et al 2009;Yamashita et al 2010;Sun et al 2011;Sun et al 2013;He et al 2014;Pejic et al 2015). Bamboo pulp fibers are more homogenous in structure and properties than man-made regenerated cellulose fibers (Qin et al 2010;Teli and Sheikh 2012).…”

a Cellulosic fibers were efficiently disintegrated from bamboo pulp as raw material and then oxidized using sodium periodate to introduce dialdehyde groups on their surfaces. The resultant fibers were characterized using Fourier transform infrared spectroscopy (FT-IR), Xray diffraction (XRD), and thermogravimetric analysis (TGA). FT-IR spectra demonstrated that the characteristic absorption band of aldehyde groups was present at 1735 cm -1 , confirming that aldehyde groups were successfully introduced. XRD showed that the nature of bamboo pulp fibers changed slightly after oxidation, except in the reduction of crystallinity. The aldehyde content increased with the sodium periodate content and reached a maximum of 1.41 mmol/g. The yield loss maximum was 32.4 wt%. TGA results showed that the temperature at the initial and final decomposition of the oxidized fibers was subject to the periodate dosage and that the thermal stability decreased to some extent.

“…The partial removal of lignin in the Li et al (2010) study decreased the barrier to hydrolysis considerably, and thus, enhanced the hydrolysing efficiency. Yamashita et al (2010) reported the use of an enzymatic saccharification method to obtain 399 mg glucose/g of the initial dry sample and 568 mg reducing sugar/g of the initial dry sample from bamboo. Glucose yield of 0.15 g/g was obtained from dilute acid pretreated and enzymatic hydrolysed bamboo (Kolawole et al 2016).…”

Global energy sectors are facing the crucial challenge of sustainability and diversification of energy resources. Seeking renewable resources with a sustainable supply is therefore a matter of the utmost concern. In this respect, bamboo, a renewable lignocellulosic material and non-food biomass, has great potential to be utilized to produce energy. Several studies have been conducted on a wide range of bamboo species and the results have shown that bamboo could potentially be used as a suitable fuel because it shares desirable fuel characteristics present in other woody biomass. Bamboo can be used as an energy source by converting it into solid, liquid, and gaseous fuels. However, to utilize bamboo as a high promise energy crop resource for biofuels, a secure and stable supply is required. Therefore, additional information on the availability, cultivation, and harvesting operations of bamboo is vital to ensure the practicability of the idea. The objective of this review is to highlight the potential of bamboo as an alternative source of bioenergy production, particularly in a Malaysian context, with emphasis on the concepts, pretreatment, and conversion technologies.

“…Yamashita et al (2010) no observaron producción de glucosa y azúcares reductores en la sacarificación enzimática del bambú sin pretratar. Sin embargo, en el presente trabajo el aserrín de pino sin pretratar (testigo) produjo azúcares reductores al ser sacarificado (0.43 g/L a las 96 h).…”

Palabras clave: residuo lignocelulósico, diseño factorial, lignina, sacarificación. RESUMENEl uso de residuos lignocelulósicos constituye una fuente abundante y de bajo costo, que genera, además, una solución al problema de su disposición final. El objetivo del trabajo fue evaluar el efecto de distintas condiciones de pretratamiento secuencial ácido-base de aserrín de pino, sobre la liberación de azúcares reductores en la etapa de sacarificación. El material lignocelulósico se pretrató en dos etapas: la primera, se realizó con ácido sulfúrico (PT1) y la segunda con hidróxido de sodio (PT2), ambas con tres niveles: 1, 2 y 3 % mediante un diseño 3 2 factorial. La hidrólisis enzimática se realizó a 50 ºC y 150 rpm en frascos de 50 mL. Se tomaron muestras a las 0.15, 24, 48, 72 y 96 h. Se determinó el porcentaje de lignina ácido soluble y la concentración de azúcares reductores. El nivel óptimo de cada factor que favoreció la mayor deslignificación correspondió a 3 % de ácido sulfúrico y 3 % de hidróxido de sodio. La producción de azúcares reductores no se vio afectada por el PT2, pero sí por el PT1, alcanzando un máximo para el nivel 0 del mismo (2 % de ácido sulfúrico). Se optimizó el pretratamiento secuencial ácido-base y se comprobó además que éste mejora la hidrólisis enzimática respecto al aserrín de pino sin pretratar. La cantidad de azúcares reductores obtenidos fue comparable a la obtenida por otros autores.Key words: lignocellulosic waste, factorial design, lignin, saccharification. ABSTRACTThe use of lignocellulosic waste constitutes an abundant and inexpensive source; it also offers a solution to the problem of waste disposal. The aim of the study was to evaluate the effect of different conditions of a sequential acid-base pretreatment of pine sawdust, through the release of reducing sugars in the saccharification step. The lignocellulosic material was pretreated in two stages: acid pretreatment (PT1), using sulfuric acid and basic pretreatment (PT2), employing sodium hydroxide at three levels each one: 1, 2 and 3 % in a factorial design. Enzymatic hydrolysis was carried out at 50 ºC and 150 rpm in 50 mL vials. Samples were taken at 0.15, 24, 48, 72 and 96 h. The percentage of acid soluble lignin and the concentration of reducing sugars were determined. The Rev. Int.
