It is widely believed that reducing the lignocellulosic biomass particle size would improve digestibility by increasing total surface area and eliminating mass heat transfer limitation during hydrolysis reactions. However, past studies demonstrate influences to a limited extent. Thus, this paper effect of (milled: 2 mm, 5 cut: cm cm) on rice straw conversion. Two different Ammonia Fiber Expansion (AFEX) pretreament conditions, AFEX C1 (low severity) C2 (high are used pretreat (named as AC1RS...
The interest in Oil Palm Empty Fruit Bunch (OPEFB) as a promising feedstock for bioconversion into value added products is growing fast, thus thorough analysis of its component becomes necessary.In this study, the biomass chemical composition and physical feature OPEFB was analysed to explore understand potential feedstock.National Renewable Energy Laboratory (NREL) standard protocols were used characterize determine OPEFB.Through protocol, structural non-structural constituents their...
Background/Objectives: Sodium hydroxide (NaOH) pretreatment was used to determine the effect of on chemical composition pretreated rice straw. The experiment designed measure effects in terms NaOH concentration and time mainly total carbohydrate content (TOC) lignin Methods/Statistical analysis: Compositional characterization performed based National Renewable Energy Laboratory (NREL) laboratory analysis protocols. Rice straw obtained from Sekinchan, Selangor Malaysia dried reduce moisture...
Plastic pollution has placed a significant emphasis on the need for synthesising bioplastics, such as polybutylene succinate (PBS), which is derived from succinic acid. Furthermore, environmental concerns and depletion of non-renewable fossil fuels have initiated an interest in exploring biotechnological route acid production via fermentation. Consequently, oil palm biomass might be prospective substitute costlier pure carbon source, more sustainable cost-effective due to its abundance high...
As additive manufacturing continues to evolve, there is ongoing discussion about ways improve the layer-by-layer printing process and increase mechanical strength of printed objects compared those produced by traditional techniques such as injection molding. To achieve this, researchers are exploring enhancing interaction between matrix filler introducing lignin in 3D filament processing. In this work, research has been conducted on using biodegradable fillers organosolv lignin, a...
The current world demand for succinic acid is around 30 000 tonnes per annum, which forecast to expand 6-fold by 2015, owing the introduction of biosuccinic acid. An insight into practical usage different biomass derivatives as substrates in commercial bioproduction discussed. Lignocellulosic crop stalk waste (corn straw, rice and cotton straw) appears, this case, be most promising form fermentation. Another example a low cost carbon source with high availability, crude glycerol, on other...
Expensive raw materials are the driving force that leads to shifting of petroleum-based succinic acid production into bio-based by microorganisms. Cost fermentation medium is among main factors contributing total cost bio-succinic acid. After carbon source, nitrogen source second largest component medium, which has been overlooked for past years. The current study aimed at replacing yeast extract- a costly with corn steep liquor economical Actinobacillus succinogenes 130Z. In this study,...
Abstract Scaling-up supercritical fluid extraction (SFE) for the of bioactive compounds from herbal plants is challenging, especially with presence alcohol-water as co-solvent. Hence, main objective this study to validate scale-up criteria SFE process Phyllanthus niruri ( P. ), and analyse extract safety profitability at industrial scale. The was performed by using carbon dioxide (SC-CO 2 ) ethanol–water co-solvent two operating conditions (L1: 200 bar, 60 °C L2: 262 80 °C). solvent-to-feed...
Coconut shell activated carbon (CSAC) presented excellent physicochemical characteristics for efficient conversion of oil palm frond (OPF) into succinic acid.
Abstract The recognition of cellulose nanofibrils (CNF) in the past years as a high prospect material has been prominent, but impractical extraction method from biomass remained technological barrier for industrial practice. In this study, telescopic approach on fractionation lignin and was performed by organosolv catalytic oxidation oil palm empty fruit bunch fibers. integration these techniques managed to synthesize CNF short time. Aside size, zeta potential measured at −41.9 mV, which...
Abstract Kenaf ( Hibiscus cannabinus L .), a potential fibre crop with desirably high growth rate, could serve as sustainable feedstock in the production of xylitol. In this work, extraction soluble products kenaf through dilute nitric-acid hydrolysis was elucidated respect to three parameters, namely temperature, residence time, and acid concentration. The study will assist evaluating performance terms xylose recovery. result point out that maximum yield 30.7 g per 100 dry attained from 2%...
Soluble products from oil palm frond hydrolysate (OPFH) were incorporated as the fermentation substrate for succinic acid (SA) production. To construct a reliable kinetic model production of SA OPFH, inhibitory effects during involving glucose evaluated based on modified Gompertz model. The application was found to fit well with experimental data characterizing profile and could predict maximum potential metabolite formation in form concentrations, rates, initial lag times. determined be...
