“…The OPT sap yielded 0.50 g ethanol/g sugars employing the optimised fermentation conditions. This value is slightly higher compared to that of ethanol produced from OPT sap in another study (Kosugi et al, 2010) and other renewable liquid resources as reported previously using various different strains of S. cerevisiae (Table 4). The result suggests that OPT sap has a great potential as fermentation substrate for ethanol production.…”

“…This was attributed in part to an absence of essential nutrients and nitrogen source for yeast growth thus lowering the yield of bioethanol. OPT sap, on the other hand, contains lots of amino acids (serine, alanine, glutamic acid and aspartic acid), organic acids (citric, malic and maleic acids), vitamins (vitamin B and C) and minerals (calcium, magnesium and chloride) (Kosugi et al, 2010), hence it is a good medium for yeast growth in fermentation. The OPT sap yielded 0.50 g ethanol/g sugars employing the optimised fermentation conditions.…”

“…Typically, the sap of OPT will not be utilised and will be discarded as waste. According to Kosugi and Mori (2007), freshly felled OPT may contain up to 70-85% of sap based on the weight of the whole trunk. The amount of fermentable sugars was found nearly 10% from the sap of the inner trunk.…”

Aims: Oil palm trunk (OPT) can be a potential biomass from replanting activities for biomass-to-liquid (BTL) particularly in bioethanol production. The OPT contains higher carbohydrates compared to other oil palm biomass, thus has better advantages as feedstock for biofuel. To realise this, the feasibility of using oil palm trunk (OPT) sap as a substrate for bioethanol fermentation was explored via optimising the various culture conditions (pH, temperature, inoculum size, nitrogen source, dilution effect and growth medium) using Saccharomyces cerevisiae. Methodology and results: A total of six parameters were tested for optimising bioethanol production i.e. pH, temperature, inoculum size, nitrogen source, dilution effect and types of medium. Results showed that the optimum conditions for OPT sap in bioethanol production were at pH 4.0, temperature of 30 °C, inoculum size of 10 % (v/v), without requirement of nitrogen supplementation and substrate dilution. A fermentation period of 24 h was best for bioethanol production and resulted in bioethanol production, formation rate and yield of 47.5 g/L, 1.98 g/h and 0.50 g/g, respectively. Conclusion, significance and impact study:The study has clearly demonstrated that high efficient bioethanol production from OPT sap is possible but it is susceptible to various fermentation influencing parameters. This study could establish an effective and sustainable utilisation of waste OPT especially its sap as a lignocellulosic biomass supplement from the oil palm industry for second generation biofuel production.

“…The frond is used as fodder, albeit on a small scale (Kawamoto et al 1999), while the extracted flesh fiber and kernel shell are mainly used as fuel for energy (Husain et al 2002). Investigations into the manufacture of pulp and paper from EFB (Jiménez et al 2009, Leh et al 2008, and bio-ethanol production from sap obtained by squeezing old oil palm trunks felled for replanting (Kosugi et al 2010) are ongoing; however, their commercialization remains insufficient to date.…”

Subcritical water extraction of low-molecular-weight phenolic compounds from oil palm biomass (trunk, bark, petiole, rachis, leaves, empty fruit bunch fiber, midrib spine leaflets, stalk of fruit bunches, flesh, kernel shells, and albumen) was conducted. It was elucidated that gallic acid, protocatechuicaldehyde, p-hydroxybenzoic acid, p-hydroxybenzaldehyde, vanillic acid, syringic acid, vanillin, syringaldehyde p-coumaric acid and ferulic acid, all of which could be used as 2-pyrone-4,6-dicarboxylic acid (PDC) precursors, were contained in all parts of oil palm, although their composition differed. The peak yield of p-hydroxybenzoic acid was obtained among the PDC precursors. With regard to extraction conditions, temperature: 200°C, time: 20-60 min, and liquor ratio: 50-125 were the most efficient. The kernel shell exhibited the highest yield of PDC precursors, followed by the trunk, empty fruit bunch fiber, and bark. The results of our study indicate the oil palm is a potentially valuable source of PDC precursors.
