Resumen

Oil palm empty fruit bunch (EFB) is one of the major solid wastes from palm oil processing. EFB is a lignocellulosic biomass and has the potential to be converted into microbial oil through biochemical routes, where the oils can be further used for biodiesel production. This PhD research aimed to develop and optimise a process for microbial oil production from EFB. The microbial oil production process involves cultivation by oleaginous microorganisms including microalgae, yeasts and fungi on EFB hydrolysates as carbon substrates. The study demonstrated that EFB is a promising low cost non-food

Resumen

Effects of various pollen types on the fruit growth and development in two maternal cultivars of Omani Date Palm were studied in the Northern Batinah region of the Sultanate Oman. Discrete stages in the development were identified, quantified and examined with regard to important variables including fruit set, weight, size, maturity, chemical composition, appearance and yield. Procedures were developed to compare across the different maternal cultivars and temperature environments. The pollen types were distinct in their effects, particularly as regards weight, time to maturity, ripening, suga

Resumen

Dates are the fruit of the palm, which the Greeks call “Phoenix”, a word taken from the Phoenician language. Saudi Arabia is currently one of the largest dates producing countries in the world. There are several varieties of dates grown in Saudi Arabia. Date fruits contain compounds that are potentially bioactive, with many health benefits; for example, vitamin E, carotene (precursor for vitamin A) and phenolic compounds. Dates represent an excellent source of antioxidants due to their high concentrations of phenolic compounds as well as the presence of selenoproteins. Moreover, dates are also

Resumen

In Malaysia, oil palm is the main commodity crop and has strongly contributed to the country’s economic development. However, the industry is facing several challenges including diminishing land resource for expansion. One of the targets to ensure oil palm sustainability is to increase yield per unit area without affecting its quality and with minimal impact to the environment. The non-synchronized ripening process and shedding of the fruits is among the factors that limit yield improvement and affect oil quality. Thus, the present study was conducted to deepen our understanding of the changes

Resumen

The oil palm industry in Malaysia is striving to show that it uses a sustainable approach in order to be accepted internationally and ensure palm oil remains a major commodity in Malaysia. The Malaysian government has already prohibited the burning of oil palm wastes leaving a problem of waste disposal.

Resumen

The application of crop residues is one of the most common agricultural practices used to maintain soil ecosystems and crop productivity. This thesis focuses on the oil palm (Elaeis guineensis) agroecosystem, an important tropical crop that has expanded rapidly over the past four decades. Both land conversion and business-as-usual practices within the plantations have contributed to soil degradation. The application of oil palm residues, such as empty fruit bunches (EFB) and oil palm fronds, are thought to have positive effects on the soil ecosystem; yet there is currently a deficit of knowled

Resumen

La production de dattes ne cesse d’augmenter d’une saison à une autre ce qui engendre des pertes essentiellement lors des étapes de manutention et de commercialisation. De plus, l’étape de manutention post-récolte joue un rôle important dans le maintien de la qualité des dattes. Dans ce cadre et afin de préserver les qualités organoleptique et nutritionnelle des dattes après récolte tout en améliorant leur valeur commerciale, des essais de conservation et de traitement post-récolte ont été mis en place. L’effet de la conservation des dattes en fonction de la température, du temps, de l’utilisa

Resumen

L’intégration des fibres naturelles cellulosiques de plantes annuelles ou de résidus agricoles ou agro-industriels dans l’élaboration de matériaux de structures composites et le développement de nouveaux liants biosourcés sont aujourd’hui un domaine de recherche d’intérêt croissant. La thèse s'est déroulée dans le cadre du programme « Eco-panneaux », dont les deux objectifs principaux furent tout d'abord de valoriser les fibres végétales d’origine tunisienne comme l’alfa, le jonc et les folioles de palme et ensuite d'évaluer le potentiel d'espèces végétales tunisiennes dont les écorces sont ri

Oxy-fuel combustion and CO2 capture from flue gases is a near-zero emission technology that can be adapted to both new and existing pulverized coal-fired power stations. In this study, the combustion characteristics of PEFB, Australian coal and their blend with various blending ratios were studied. The results indicated that replacing N2 by CO2 in the combustion atmosphere with 21% of O2 caused increase in the ignition temperature and burnout te

Resumen

Palm oil empty fruit bunches (EFB) is an abundant and cheap lignocellulose material in South East Asia. Its use as the sole medium for producing lignocellulose-hydrolyzing enzymes would increase its commercial value. A newly isolated Aspergillus niger DSM 26641 was investigated for its capability of producing hemicellulases in EFB hydrolysate obtained by treatment with pressurized hot water (1-20%, w/v) at 120-180◦C in a 1 L Parr reactor for 10-60 min. The optimal hydrolysate for the fungal growth and endoxylanase production was obtained when 10% (w/v) of empty fruit bunch was treated at 120◦C

Resumen

The açai palm fruit has recently become the focus of numerous research endeavors due to its extraordinary antioxidant content. However, little is known about the fruit’s phytochemical rich oil, which is a by-product of the açai pulp. Therefore, the aim of this study was to investigate the phytochemical content of açai oil and its relation to oxidative stability. A total of 206 mg/kg of chlorophylls, which included chlorophyll a as well as four chlorophyll derivatives were tentatively identified by HPLC in crude açai oil (CAO). Two predominant carotenoids (216 mg/kg β-carotene and 177 mg/kg lut

碩士<br>國立中正大學<br>化學工程研究所<br>107<br>Activated carbon (AC) is regarded as one of the most promising active materials for high performance supercapacitor (SC) owning to its high specific surface area and theoretical specific capacity. In this study, oil palm empty fruit bunch (EFB) which is the agricultural residue was employed as precursor to produce ACs which were fabricated by a series of cleaning, carbonization and chemical activation processes. The as-produced AC possesses a specific surface area of 2774 m2/g, which is very high among the AC produced from biomass materials. In order to enhanc

Resumen

碩士<br>國立中興大學<br>園藝學系所<br>100<br>Recently, global warming has caused gradual increase in temperature during autumn and winter seasons. This may affect the formation of anthocyanin in wax apples in Taiwan. The peel color of ‘Pink’ wax apple is red at lower temperatures, but the peel color of ‘Big Round Leaf’ wax apple is red at higher temperatures. In order to understand the differences in anthocyanin biosynthesis between the two cultivars, we first analyzed the anthocyanin composition of these two cultivars, then we analyzed how phenylalanine ammonia-lyase (PAL) activity and ethylene inhibitors
