“…Other compounds, such as total lignin (21.87%), ash (1.90%), extractives in water (3.80%), extractives in ethanol (10.01%) and moisture (6.46%), were similar to those reported in the literature (Hamzah et al, 2011;Ferrer et al, 2013;Palamae et al, 2014). However, the differences seen in the OPEFB compositions as compared with other studies could be due to the maturity degree of the fresh fruit bunches, the geographic regions, and the soil conditions (Hazir et al, 2012).…”

The aim of this study was to evaluate the effect of different process conditions, such as the sulfuric acid concentration, contact time, solid:liquid ratio and particle size, on the xylose recovery and the formation of by-products from oil palm empty fruit bunch (OPEFB) with dilute-acid hydrolysis. Moreover, an adapted and non-adapted strain of the yeast Candida guilliermondii was used to obtain xylitol from the optimal hydrolysate. Xylose, glucose, hydroxymethylfurfural (HMF) and acetic acid in the acid hydrolysate were analyzed with high performance liquid chromatography (HPLC). A BoxBehnken-based design was used to find the combination of factors that maximized the formation of xylose in the hydrolysate optimization process. The fermentation to obtain xylitol from the optimized hydrolysate of OPEFB with adapted and non-adapted C. guilliermondii strains was made in 100 ml Erlenmeyer flasks at 30°C for 96 h at 200 rpm in an incubator shaker. The maximum xylose concentration (32.59 g L -1) was obtained at 121°C, for 30 min, with a 1:8 solid:liquid ratio, 2% acid concentration and particle size of around 4 cm. With the same conditions, the inhibitor concentrations, such as HMF, glucose and acetic acid, were 0.023, 1.033 and 11.078 g L -1, respectively. The optimized conditions were the same as previously described. The higher xylitol productivity (10.3 g L -1) and yield (0.43 g g -1) were obtained by fermentation with non-adapted C. guilliermondii strains from the optimized hydrolysate of OPEFB without the need for detoxification. It is not necessary to make an adaptation of C. guilliermondii in the optimized hydrolysate of OPEFB to produce xylitol.

“…A prior hydrolysis of the relatively recalcitrant lignocellulosic substrate to simpler small molecules greatly improves the rate of subsequent production of hydrogen. Oil palm empty fruit bunch (OPEFB) is an abundantly available lignocellulosic residue in certain tropical parts of Asia [14] and can be used to produce biohydrogen http://dx.doi.org/10.1016/j.apenergy.2015.08.027 0306-2619/Ó 2015 Elsevier Ltd.

“…Organic compounds obtained via hydrolysis of widely available lignocellulosic residues [12][13][14] are promising substrates for inexpensively producing biohydrogen. Although lignocellulosic residues can be fermented directly to hydrogen by some bacteria, the rate of this fermentation is extremely slow as much of the macromolecular substrate is inaccessible to the microorganism [15,16].…”

“…The types of biomass produce by oil palm are EFB, mesocarp fiber, kernel shells, fronds and trunk (Uemura et al, 2013). The EFB comprises of 17-33% of hemicellulose, 43-65% of cellulose and 13-37% lignin on the dry weight basic (Palamae et al, 2014). Lignocellulosic agriculture biomass consists of cellulose, hemicellulose and lignin, together with smaller amount of pectic substance.…”

Lignocellulosic biomass is inexpensive, most abundance and provide the large-scale. Lignocellulosic are compose into three structures which are cellulose, hemicellulose and lignin. Empty Fruit Bunch (EFB) has the highest composition of cellulose, hemicellulose and lignin among the abundance fiber like coir, corn, bagasse and kenaf fiber. Torrefaction was the process pretreatment of biomass materials in inert atmosphere (nitrogen) in temperature range 200 to 300 °C by using microwave heating. Microwave controlled all the parameter which is power level (W), temperature (°C), volume of nitrogen (ml/min) and mass of sample (g) during the torrefaction process. In this study, the analysis of raw and torrefied EFB was done according to TAPPI standard method except hemicellulose which data was collected through equation. Result acquired reveals that the highest percentage in extractive, holocellulose, α-cellulose, hemicellulose and lignin was be found in raw EFB compared to other torrefaction EFB due to the degradation of content during torrefaction process. The degradation of hemicellulose was the takes place in temperature range 200 to 350 °C or even lower, whereas the degradation of cellulose and lignin occurs when 300 °C and above. This study determined EFB as useful alternative resources in feedstock material steam for power plant application.
