| 内容記述 | Palm oil industry is one of the Malaysian top commodities, producing abundant of lignocellulosic biomass as waste. Although a lot of studies have been done for these biomass, oil palm frond (OPF) has been neglected due to the current good agricultural practise, where it is required to be left in the oil palm plantation for nutrient recycling. However, a recent finding showed that the petiole parts of the OPF is rich in sugars, which can be extracted by pressing the petiole. As for the petiole biomass after pressing, it require pretreatment to allow enzymatic hydrolysis to take place smoothly. In the first chapter, a literature studies was carried out to understand the gap in the research for OPF, while trying to relate it with excessive energy of palm oil industry. OPF from the oil palm plantation involves a volume of 83 million tons in Malaysia alone. As it was suggested earlier that the petiole alone is a good source for sugars, its utilization is restricted due to the good agricultural practise. Therefore, the second chapter discuss the comparison of oil palm biomass volume to justify the reason of OPF selection. Detailed composition of the OPF components was also studied to understand which parts of the fronds actually contribute to the nutrient recycling, as well as to suggest whether it is safe or not to take the petiole out of the plantation. Amongst the four components, namely petiole, stem, rachis and leaflet, we found that the main contributor for the nutrient recycling by OPF is actually the leaflet, while the petiole has only a little effect. We also suggest that the logistic issues regarding the transportation of the OPF petiole from the plantation to the palm oil mill, can be solved by adding extra cart behind the existing truck. Therefore we do not need extra truck and driver. Third chapter is mainly about the pretreatment and cellulose hydrolysis of the petiole residue. We suggest that reuse of the oil palm steam (superheated steam, SHS) for pretreatment of petiole residue will be beneficial and profitable for the palm oil mill. The use of SHS is found to be superior as compared to a wet disc milling (WDM) in term of pretreatment duration and practicality in the palm oil mill. Upon treating the pressed petiole, we found that pretreatment of petiole at 180°C for 10 minutes yielded the highest sugars yield amongst the range of the treatment, which was achieved by using a low 10 FPU cellulase activity. This resulted in improvement of specific biosugars yield by 79.91% from untreated petiole residue. This short time pretreatment improvement is mainly due to the changes in specific surface area, particle size and properties of lignocellulose components which are discussed in detail throughout this study. We also suggest that pretreatment time also affected by residual oil such as found in oil palm empty fruit bunches (OPEFB) and oil palm mesocarp fibre (OPMF), therefore the petiole has advantage for not containing the oil residue. In the fourth chapter, we study the effect of replacing the commercial nutrients for yeast by petiole’s juice in bioethanol fermentation. This is due to a parallel study’s finding which shows that the juice is rich in nutrients and some vitamins, which can support the yeast fermentation. Usage of petiole’s juice to replace commercial nutrients in bioethanol production may reduce the production cost. We found that there was no significant difference in the fermentation performance when we replaced commercial medium with petiole juice. This concludes that the petiole juice is suitable as a supplement for bioethanol fermentation of OPF petiole hydrolysate. | |||||||
