Available in PDF, EPUB and Kindle. Book excerpt: Fossil fuels were used in large quantities as a solvent and chemical feedstock in various industries. Due to limited stock of fossil fuel and rapid increase of energy demand in Malaysia, bioethanol has become a very important and necessary alternative energy source in order to replace the limited fossil fuel stock. Hence, this paper presents the study on bioethanol production by using oil palm trunk (OPT) sap which mainly focusing on substrate concentration effect toward the yield, productivity rate, and kinetic behaviour of cell growth in different substrate concentration This research was carried out by using Saccharomyces cerevisiae Kyokai No.7 in 200mL conical flask, under 30oC anaerobic condition. The research are focusing on the inoculums culture preparation, fermentation process, sample preparation, and analyzing methods. It was found that bioethanol production is increase when substrate concentration increase, from 14g/L in 60% substrate concentration, followed by 18g/L in 80% OPT sap to 22g/L in 100% OPT sap. With the highest sugar content in the medium, S. cerevisiae can produce faster ethanol production within 30 hours of fermentation duration. However, high bioethanol concentration in the process will cause the cell growth rate falls due to the product inhibition. Besides, glucose consumption rate were found out that inversely proportional to the substrate concentration whereas ethanol production rate and cell growth rate were directly proportional to the substrate concentration. Moreover, specific bioethanol production yield was found out that exceed 0.482, 0.516, and 0.465 for 60%, 80%, and 100% of substrate concentration respectively. These results will be useful in the future scale up processes.

Available in PDF, EPUB and Kindle. Book excerpt: Old oil palm trunk becomes a promising source of sugars by proper aging after logging and, thus, its sap can be a good feedstock for bioethanol. It aims to develop alternative resources waste to wealth for bio-ethanol production using available biomass in this country. To produce high production of bioethanol, determine fermentation conditions are important in culture fermentation to predict the optimum temperature and optimum inoculums size. The process selection includes preparation of pure culture, yeast activation, fermentation profile, and validation between two types of yeast, batch fermentation and analysis of the data. The overall process performance is measured by the productivity and quality of bioethanol produced. Glucose was thoroughly nearly consumed after 48 hour for the fermentation profile. Validation experiment between showed that Saccharomyces cerevisiae Kyokai 7 produce high yield of ethanol. The effects of temperature (25- 40 oC),and percentage inoculums (5- 15 %v/v) on ethanol yield were assessed by using 24 full factorial design (FFD) and validated statistically by analysis of variance (ANOVA). The optimum temperature is 25.29 celcius and optimum inoculum size is 10.54 % .Saccharomyces cerevisiae Kyokai 7 produced 41.43% higher ethanol compared to S.cerevisiae. The mean percentage error is 10.32 in screening parameter experiment. The influence of temperature was found to be more pronounced on ethanol yield compare to others parameter.

This book was released on 2012 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil palm trunk (OPT) is generated from the replantation of oil palm trees at every 25-30 years interval, left as troublesome waste as it becomes the source of infection to young oil palm trees. This OPT contains a high amount of ready-to-use sugar in the form of sap which can be directly fermented to the most fermentation products. The fermentation process for ethanol production from OPT sap was evaluated in order to produce larger amount of bioethanol. The feasibility of yeast S. cerevisiae to produce bioethanol from OPT sap was investigated along with the effect of different strains of S. cerevisiae and different pretreated mediums. It was proven that yeast S.cerevisiae was able to produce bioethanol even though the OPT sap undergoes less pretreatment compared to the previous works done by the other reseachers. The highest bioethanol yield and productivity had been obtained by using S. cerevisiae Kyokai no.7 in heat sterilized sap. The effects of temperature, initial pH, agitation rate, percentage inoculum and time of incubation were explored using 2-level full factorial design in order to find out the main factor that affecting bioethanol fermentation from the OPT sap. The factors of temperature, initial pH and agitation rate were chosen for optimization study based on the higher percentage contribution (>5 %) and lower p-values (

This book was released on 2014 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents the kinetic study of bioehanol production using Oil Palm Trunk Sap (OPTS) by Kluyveromyces marxianus. Bioethanol have been discovered as the substitute of petrol that is biodegradable and less toxic than fossil fuels. Oil palm trunk can be used to produce bioethanol from its sap because it contains high glucose and other types of sugars. This study is focus on studying the kinetic parameters of bioethanol production from oil palm trunk sap (OPTS) using Kluyveromyces marxianus. By analyzing specific growth rate, sugar consumption rate and ethanol production rate the kinetic parameters can be determined. The analytical techniques for bioethanol production and substrate consumption were monitored by high-performance liquid chromatography (HPLC) and cell dry weight (CDW) for growth profile. In this study, pH and temperature were varied to study the effect of different pH (3, 4, 5, 6, and 7) and temperature (25oC, 30oC, 35oC, 40oC, and 45oC). The highest ethanol concentration was produced at pH 5 which is 26.75 g/L and at temperature 35oC ethanol concentration production was 45.06 g/L.

This book was released on 2013 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: Malaysia is the one of world's largest producer of palm oil. Waste from palm oil production factories has been increasing rapidly and one of the serious problems in the palm oil fruit processing is managing the waste generated by the processes. Recent studies showed that butanol can be used as excellent renewable liquid transportation fuel. In this study, oil palm trunk sap is used as the substrate. The objective of this study is to compare the production of biobutanol from biomass waste (oil palm trunk sap) via fermentation process using different microorganisms. The fermentation type done was submerged fermentation. Fermentation was conducted for five days at 37 0C. Samples were taken for every 6 hours for 3 days, then for every 12 hours. Samples taken were analyzed using gas chromatography-flame ionization detector (GC-FID) and high performance liquid chromatography (HPLC) was used to analyze sugar composition in OPT sap. UV Spectrophotometer is used to analyze biomass. Oil palm trunk (OPT) sap contains sucrose as its dominant sugar followed by glucose, fructose and galactose. Based on the analysis, acetone, butanol and ethanol were produced. Comparisons between the two strains Clostridium acetobutylicum and Clostridium beijerinckii were made, and C. beijerinckii showed higher production of acetone, butanol and ethanol. The highest yield for butanol production by C. acetobutylicum and C. beijerinckii were 13.910 g/L and 15.301 g/L and highest production of ethanol were 11.17 g/L and 12.09 g/L. 4.13 g/L and 4.49 g/L acetone was produced by C. acetobutylicum and C. beijerinckii. Based on this study, it is concluded that OPT sap is preferable substrate to produce butanol by using C. beijerinckii.
