Aims:Bioethanol is an environmental friendly energy source with a lot of great prospective and become an alternative to fossil fuels .Oil palm frond juice (OPFJ) is a potential sources of sugars for bioethanol production. The present study aimed to optimize bioethanol production. Methodology and results: Bioethanol fermentation was carried out by Saccharomyces cerevisiae HC10 using OPFJ as substrate in bioreactor with 1.5 L working volume. Growth profile was performed for 42 h with sampling every 3 h interval. Effect of agitation speed (rpm) and volume of OPFJ were screened to select significant factor for high production of bioethanol. Agitation speed at 175 rpm and volume of oil OPFJ; 40% gave 5.25 g/L and 4.52 g/L of ethanol and biomass concentration, respectively. These parameters were further investigated via central composite design (CCD) of Response Surface Methodology (RSM) to maximize bioethanol production. The suggested optimum conditions for bioethanol production were agitation speed at 152 rpm and volume of OPFJ at 39.71% in which giving ethanol concentration of 4.79 g/L. Growth profile after optimization indicated that the highest ethanol concentration (5.75%) was achieved after 15 h of fermentation. Kinetic studies indicated that ethanol yield coefficient (Yp/s) due to consumption of OPFJ and productivity of ethanol was 3.5 fold and 25% increased compared to before optimization, respectively. While, in term of ethanol yield about 9% increased was observed. Conclusion, Significance and Impact of study: This showed that OPFJ can be an alternative new feedstock for bioethanol production using S. cerevisiae HC10.

“…Therefore, the estimated output energy from 1 tonne OPF is 3100 MJ with the assumption that the lower heat of bioethanol combustion is 21.2 MJ/l [25]. The saccharified OPF residue estimated at 146 kg per tonne of OPF processed will be used as biofuel to feed the existing boiler at 77% efficiency.…”

In this case study, a preliminary assessment on the bioethanol production from oil palm frond (OPF) petiole sugars within an integrated palm biomass biorefinery was carried out. Based on the case study of 4 neighbouring palm oil mills, approximately 55,600 t/y of fermentable sugars could be obtained from OPF petiole. The integrated biorefinery will be located at one of the 4 mills. The mill has potential excess energy comprising 3.64 GWh/y of electricity and 177,000 t/y of steam which are sufficient to run the biorefinery. With 33.9 million litres/y of bioethanol production, the specific production cost of bioethanol

“…The OPT saps by were collected mechanically pressing the oil palm trunks, according to the method described by Murata et al (2013), using a hydraulic press for 0 days and 60 days respectively using a specially designed compression machine by Murata et al (2013). The trunk used in this study was at 25 years of age, tenera type from Ara Kuda, Kedah, Malaysia.…”

In this study, freshly squeezed oil palm trunk sap (OPT0sap) and sap of oil palm trunk that had been stored for 60 days (OPT60sap) were characterised and compared with a nipa sap (Nsap) as a control sample in terms of their physico-chemical and functional properties. The results indicated that when the two OPT saps were compared, trunk storage significantly impacted the latter sap's composition. As the storage period increased, the sap became darker and its sugar content increased. Further, the OPT saps showed significant amounts of antioxidant contents, with greater nutritional value compared to Nsap. The OPT0sap's viscosity was found to be the lowest, whereas the Nsap's was the highest, with values of 0.87 ± 0.07 mPa.s and 3.77 ± 0.09 mPa.s, respectively. The OPT0sap had the lowest pH, whereas Nsap had the highest. In conclusion, in comparison to Nsap, the OPT saps demonstrated better features in terms of antioxidant capacity and higher reducing sugar content. However, OPT saps had greater acidity and darker colour.
