This book was released on 2010 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Owing to the increasing volume of palm oil mill effluent (POME) wastewater generated, disposal remains as perennial problem and its bioconversion has been considered as an option for pollution control (C.N. Hipolito et al., 2008). Thus, the availability of an inexpensive raw material; POME which will used in this research is essential if solvent fermentation is to become economically viable. In Malaysia, POME represents an alternative cheap carbon source for fermentation processes that is attractive in both economic and geographical considerations. The mainly research purpose is to study the production of butanol from the anareobic fermentation of solventogenic bacteria (clostridium beijerinkii, ATCC 51743) by using POME as the fermentation media. The scope of the research is to study the effect of fermentation time and temperature to the butanol production. The fermentation is based on batch fermentation in schott bottle. It is an anaerobic fermentation and the strain, Clostridium Beijerinckii (ATCC 51743) was treated strictly in an anaerobic condition. Optimum conditions that were maintained in this research are the substrate concentration and agitation rate. POME and Reinforced Clostridia Media (RCM) were used as the growth medium in this batch culture. The fermentation temperature that were used in this study are 35°C, 40°C and 45°C while the fermentation time that were used are 48 to 72 hours respectively. The results indicated that the concentration of butanol will decreases as the temperature increases. The highest concentration of butanol that produced by POME was 0.224 g L-1 at 35°C by 72 hours of fermentation. From this study, it is showed that POME can produce butanol at optimum fermentation temperature at 35°C in 72 hours of fermentation time. Hence, the result also showed that POME is viable to use as growth medium to produce butanol.

This book was released on 2010 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study is mainly focusing on butanol production from palm oil mill effluent (POME) by anaerobic fermentation using Clostridium acetobutylicum. Despite that untreated POME could bring severe effects to environment, POME also can be used as the main substrate due to abundant supply and it potentiality to be utilised by saccharolytic clostridia in butanol fermentation. Reinforced Clostridia Medium (RCM) was functioned as control medium. This study was also to investigate the growth profile rate and the consumption of glucose by C. acetobutylicum during fermentation for 72 hour at 37°C. Fermentation was carried out in 250 mL Schott bottle at a working volume of 150 mL. Other parameters were kept constant at pH 5.8 for POME, pH 6.8 for RCM and 10% inoculum. The effects of substrate concentration and agitation rate in producing butanol were studied. Substrate concentrations used were 70%, 80% and 90% while for agitation rates were 0 rpm, 100 rpm, 175 rpm and 250 rpm. Butanol produced from the fermentation was analyzed using gas chromatography equipped with flame ionization detector (GC-FID). Growth profile rate of C. acetobutylicum in POME and RCM were measured using UV-Vis spectrophotometer. Glucose concentration was measured from the calculation of the amount of glucose consumed by dinitrosalicylic acid (DNS) method which monitored using UV-Vis spectrophotometer. This experiment were started by clostridia cultivation and then followed by fermentation medium preparation, inoculum preparation, fermentation process for 72 hours and fermentation product analysis. The highest butanol yield in POME was 0.3485 g/L at 70% concentration and 175 rpm while maximum butanol production was produced in 90% RCM at 175 rpm which was 0.5034 g/L. In conclusion, lots of hard work and precaution steps need to be taken in order to make sure higher butanol can be produced at theoretically substrate concentration which is 90% and agitation rate at 200 rpm.

This book was released on 2012 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: Few decades ago, world is totally depends on fossil fuel as energy source that currently most economically available source for personnel and commercial used leads in diminishing interest on development fermentation of biofuel industry. Unfortunately, due to constant conflict in the oil-supply regions and depletion of fuels oils supply resulted in viable of solventogenic fermentation industry in the world. Besides that, combustion of fossil fuel will produce various particle and gas that contribute to crises of environmental problem such as acid rain as well as greenhouse effect which is key factor in global warming. Thus, pressing need in reviewing the solventogenic fermentation of biofuel from a viable alternative sustainable and renewable energy resources that more renewable, more efficient and safer for environment. Unfortunately, the solventogenic fermentation needs to overcome high cost of production substrate together with low fermentation yield in order to compete with solvent production from fossil fuel. Palm oil mill effluent (POME) is abundant agricultural waste in Malaysia, shows great potential in used directly as alternative fermentation substrate. The objective of this study is manly to study the effect of temperature, agitation rate and inoculums concentration as variable factors that significantly influenced solvent production from palm oil mill effluent (POME) by Clostridium beijerinkii ATCC 51743. Analysis of total solvent production was done by using gas chromatography and isobutanol has been used as internal standard. Results that obtain from the study effect of 5 to 25% inoculums concentration to total solvent concentration show that the total solvent concentration will decrease as inoculums concentration increase. The highest production of total solvent is at 10% of inoculums concentration with 0.719 g/L production. Besides that, the study effect of 25 to 35 °C temperature to the total solvent production shows that concentration of total solvent production will decreases as temperature increase. The highest production is 0.568g/L at 30°C. Meanwhile effect of 50 to 250rpm agitation rate to the total solvent production shows that as agitation increases, total solvent production will decrease where the highest total solvent production was recorded at 150rpm with 0.675g/L. It can be conclude that, the temperature, agitation rate and concentration inoculums will be the significant parameter that affected production solvent from POME by Clostridium Beijerinckii (ATCC 51743).In addition, applying the Response Surface Methodology (RSM) was recommended for this study in order to determine the optimum level in enhances the solvent production.

Book excerpt: In this present experiment, the main objective is to study the effect of substrate concentration in producing higher butanol compared to ethanol by using Clostridium acetobutylicum. Palm oil mill effluent (POME) was used as the main substrate in this fermentation because it imposes negative effect towards the environment which in vast amount besides the availability as a low cost substrate and reinforced clostridium medium (RCM) was used as a control substrate. Study was also done to investigate the growth profile of C. acetobutylicum, type of sugars in POME, and glucose consumption of C. acetobutylicum during fermentation. The HPLC analysis result for sugar component showed that the reducing sugars; fructose, glucose, galactose, sucrose and lactose exist in POME and are utilized as substrate for solvents fermentation by C. acetobutylicum. Main study on the effect of four substrate concentrations 70%, 80%, 90% and 100% in POME and RCM were tested using Schott bottle as fermentor in anaerobic chamber to maintain the anaerobic condition for C. acetobutylicum growth condition for 72 hours at temperature of 35oC, pH 5.8 and speed of 200 rpm. The results showed that butanol and ethanol were produced at the end of the fermentation hence proving POME is a viable substrate for the fermentation. After 20 hours fermentation it was observed that at 90% substrate concentration butanol produced was higher compared to ethanol. However, in overall the result showed higher ethanol production compared to butanol production for all the four different substrate concentration throughout the experiment. The core factor contributing in this result is the substrate inhibition by butanol besides the phenolic component in POME which also acts as inhibitor, strain degeneration, and also extraction of butanol from fermentation broth. In conclusion, many efforts need to be taken to ensure higher butanol can be produced especially in decreasing the inhibition factor towards butanol.

Book excerpt: Biofuels production through fermentation from renewable waste has been put more to focus in mid 20th century till now. Main focus of the research is to determine optimum fermentation time to obtain maximum concentration of butanol and ethanol via ABE fermentation. The ABE fermentation is a two phase chemical production which is from acidogenesis into solventogenesis. The fermentation is caused by clostridia bacteria and in this case of study is Clostridium acetobutylicum pattered NCIMB 13357. The main substrate for nutrient in this study is Palm Oil Mill Effluent (POME) which freshly taken from Lepar Hilir, Pahang. Through the research, POME was found to contain majorly of pentose and carbohydrate substance such as galactose, glucose, fructose, sucrose and lactose. The research parameter is fermentation time at 72, 80, 48 and 60 hours. The experiments start from medium preparation, cultivation of bacteria, inoculation, fermentation and lastly analysis of product. All standard solution is made in order to standardize the reading of concentration of product and substance analyzed. The condition for bacteria environment is set to anaerobic and optimum pH at 5.8, temperature at 37 0C and agitation speed is set at 200 rpm along ABE fermentation. Final result shown that at fermentation time of 40 hours, the maximum value of 0.07 g/L of butanol was produced, while for ethanol is 83.499 g/L at 20 hour fermentation time. POME is encouragingly valid for use as fermentation media as it contain many utilizable substrates for Clostridium acetobutylicum.

This book was released on 2017 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clostridium carboxidivorans (NCIMB 15243) is a well-known acetogenic bacterium with the capability to produce acetyl-CoA and subsequently biofuel products such as ethanol and butanol from waste gas such as CO2 and H2. To be more specific, C. carboxidivorans can utilize CO2 and H2 via the reductive acetyl-CoA or Wood-Ljungdahl pathway to produce organic acids, such as acetate and butyrate, and alcohols, such as ethanol and butanol. Clostridium beijerinckii (NCIMB 8052) produces CO2 and H2 as waste products from converting pyruvate into acetyl-CoA. Because these two different Clostridium strains use two different, but very similar, metabolic pathways that rely on two different substrates to produce ethanol and butanol, both individual strain and co-cultured fermentative profiles were studied in autotrophic fermentation with CO2/H2 and heterotrophic fermentation with glucose as carbon and energy source. During both fermentations, initial medium pH values of 6.1 and 7.1 were studied for optimal ethanol and butanol production without any pH adjustments during glucose and CO2/H2 gas fermentations. Both fermentations were performed in serum bottles containing 50 ml of CGM medium. All serum bottles were incubated in a shaking incubator with agitation at 150 rpm at 25C or 37C. We observed that more acids and alcohols were produced with the higher initial pH of 7.1 in glucose and CO2/H2 gas fermentations. To explore the effect of temperature shift on alcohol production, serum bottles were incubated in 37C shaker for the first 24 hours then in 25C shaker for the rest of fermentation. During the glucose fermentation, two co-culture batches were able to produce significant amount of butanol by utilizing temperature shift technique. Since we have observed that C. carboxidivorans can more effectively convert CO2 into ethanol rather than butanol, we also examined the effect of co-culturing it with C. beijerinckii in gas fermentation. Co-culture batches were able to boost butanol productivity in CO2/H2 gas fermentation by converting acetyl-CoA produced by C. carboxidivorans prior to the second inoculation of C. beijerinckii at 37C.

This book was released on 2010 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Malaysia, the government has implement policy instruments aimed at promoting the production of butanol and ethanol as an alternative to renewable energy. The objective was to study the effect of inoculum concentration on butanol and ethanol production and besides that, the study also focused on growth profile of Clostridium acetobutylicum and glucose consumption in POME and RCM. The methods begin with palm oil mill effluent (POME) analysis using High Performance Liquid Chromatography (HPLC). The process continued with the microbial fermentation and each inoculums concentration at 5% v/v, 10 % v/v and 15 % v/v were prepared in Reinforced Clostridia Media (RCM). POME as an alternative medium was sedimented for 24 hours, and has been prepared at pH 5.8, diluted with 90 % substrate, deoxygenated the POME using nitrogen gas. Both medium POME and RCM were seeded with different inoculums concentration and after 3 days fermentation, the fermentation broth were undergo liquid-liquid extraction and prepared for Gas Chromatography (GC) analysis. The result obtained from POME analysis showed that galactose was the main component in POME. Moreover, the maximum butanol production for both POME and RCM medium were 0.18533% at 15% v/v (POME) and 0.00801% at 5% v/v (RCM). Result showed that increasing the inoculum concentration would reduce the fermentation time, increased the total glucose consumption and increased the butanol production. While the maximum production of ethanol were, 1.87593% at 15% v/v during 40 hours (POME) and 2.36754% at 5% v/v during 60 hours (RCM) of fermentation time. The result showed that there were significant correlation between inoculum concentration and butanol and ethanol production. Thus, it could be concluded that inoculum concentration does affect the butanol and ethanol production, besides, POME could be an alternative medium for butanol and ethanol fermentation.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Anaerobic digestion (AD) is one of the oldest biotechnological processes and originally referred to biomass degradation under anoxic conditions in both natural and engineered systems. It has been used for decades to treat various waste streams and to produce methane-rich biogas as an important energy carrier, and it has become a major player in electrical power production. AD is a popular, mature technology, and our knowledge about the influencing process parameters as well as about the diverse microbial communities involved in the process has increased dramatically over the last few decades. To avoid competition with food and feed production, the AD feedstock spectrum has constantly been extended to waste products either rich in recalcitrant lignocellulose or containing inhibitory substances such as ammonia, which requires application of various pre-treatments or specific management of the microbial resources. Extending the definition of AD, it can also convert gases rich in hydrogen and carbon dioxide into methane that can substitute natural gas, which opens new opportunities by a direct link to traditional petrochemistry. Furthermore, AD can be coupled with emerging biotechnological applications, such as microbial electrochemical technologies or the production of medium-chain fatty acids by anaerobic fermentation. Ultimately, because of the wide range of applications, AD is still a very vital field in science. This Special Issue highlights some key topics of this research field.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainable development is the most important challenge facing humanity in the 21st century. The global economic growth in the recent past has indeed exhibited marked progress in many countries. Nevertheless, the issues of income disparity, poverty, gender gaps, and malnutrition are not uncommon in the global landscape, in spite of the upward growth of the economy and technological advances. This grim picture is further exacerbated by our growing human population, unmindful resource use, ever-increasing consumption trends, and changing climate. In order to protect humanity and preserve the planet, the United Nations issued the “2030 agenda for sustainable development,” which includes but is not limited to sustainable production and consumption practices, e.g. in a sustainable bioeconomy. The hallmark of the sustainable bioeconomy is a paradigm shift from a fossil-fuel-based economy to a biological-based one, which is driven by the virtues of sustainability, efficient utilization of resources, and “circular economy.” As the sustainable bioeconomy is based on the efficient utilization of biological resources and societal transformations, it holds the immense potential to achieve the UN’s Sustainable Development Goals. This book shares valuable insights into the linkages between the sustainable bioeconomy and Sustainable Development Goals, making it an essential read for policymakers, researchers and students of environmental studies.

Book excerpt: Increase in green, renewable and sustainable energy demand due to higher environmental impacts (e.g. Greenhouse gases emissions, climate change, etc.) on consumption of fossil fuel resource put down an extra pressure on government, researchers and industrialists. Among several available biofuel options, biohydrogen is considered as one of the best environmentally clean fuel and a strong candidate to fulfil the future demand of sustainable energy resource. Although, biohydrogen production technology and its use as a fuel is still in infancy stage. Selection of most sustainable production pathway, increase in production upto industrial scale and cost efficiency are some issue still persist with the biohydrogen research. “Biohydrogen Production: Sustainability of Current Technology and Future Perspective” is giving an insight for the sustainable production of biohydrogen at industrial scale. The process of biohydrogen production is complex and to opt the best suited production system for industrial scale is a frantic task. This book will provide an in depth information on all available technologies for biohydrogen production and feedstock options to choose upon. This book is also providing information on present status of the research in the field and possibility to change future fuel economy in to biohydrogen economy. Experts views provided in the chapters by renowned researchers from all over the globe in the field of biohydrogen research made this book a cornucopia of present research and future perspective of biohydrogen. This book is targeted at the researchers working on biohydrogen as well as the bioenergy scientist planning to move towards biohydrogen research. This book will provide a platform for motivation of researchers and industrialists for innovative ideas and thoughts to bring biohydrogen production at industrial scale.

Book excerpt: Due to the possibility that petroleum supplies will be exhausted in the next decades to come, more and more attention has been paid to the production of bacterial pl- tics including polyhydroxyalkanoates (PHA), polylactic acid (PLA), poly(butylene succinate) (PBS), biopolyethylene (PE), poly(trimethylene terephthalate) (PTT), and poly(p-phenylene) (PPP). These are well-studied polymers containing at least one monomer synthesized via bacterial transformation. Among them, PHA, PLA and PBS are well known for their biodegradability, whereas PE, PTT and PPP are probably less biodegradable or are less studied in terms of their biodegradability. Over the past years, their properties and appli- tions have been studied in detail and products have been developed. Physical and chemical modifications to reduce their cost or to improve their properties have been conducted. PHA is the only biopolyester family completely synthesized by biological means. They have been investigated by microbiologists, molecular biologists, b- chemists, chemical engineers, chemists, polymer experts, and medical researchers for many years. PHA applications as bioplastics, fine chemicals, implant biomate- als, medicines, and biofuels have been developed. Companies have been est- lished for or involved in PHA related R&D as well as large scale production. It has become clear that PHA and its related technologies form an industrial value chain in fermentation, materials, feeds, and energy to medical fields.
