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.

This book was released on 2010 with total page 73 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2010 with total page 75 pages. Available in PDF, EPUB and Kindle. 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 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.

Book Synopsis The Prokaryotes by : Edward F. DeLong
Download or read book The Prokaryotes written by Edward F. DeLong and published by Springer. This book was released on 2014-10-13 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Prokaryotes is a comprehensive, multi-authored, peer reviewed reference work on Bacteria and Achaea. This fourth edition of The Prokaryotes is organized to cover all taxonomic diversity, using the family level to delineate chapters. Different from other resources, this new Springer product includes not only taxonomy, but also prokaryotic biology and technology of taxa in a broad context. Technological aspects highlight the usefulness of prokaryotes in processes and products, including biocontrol agents and as genetics tools. The content of the expanded fourth edition is divided into two parts: Part 1 contains review chapters dealing with the most important general concepts in molecular, applied and general prokaryote biology; Part 2 describes the known properties of specific taxonomic groups. Two completely new sections have been added to Part 1: bacterial communities and human bacteriology. The bacterial communities section reflects the growing realization that studies on pure cultures of bacteria have led to an incomplete picture of the microbial world for two fundamental reasons: the vast majority of bacteria in soil, water and associated with biological tissues are currently not culturable, and that an understanding of microbial ecology requires knowledge on how different bacterial species interact with each other in their natural environment. The new section on human microbiology deals with bacteria associated with healthy humans and bacterial pathogenesis. Each of the major human diseases caused by bacteria is reviewed, from identifying the pathogens by classical clinical and non-culturing techniques to the biochemical mechanisms of the disease process. The 4th edition of The Prokaryotes is the most complete resource on the biology of prokaryotes. The following volumes are published consecutively within the 4th Edition: Prokaryotic Biology and Symbiotic Associations Prokaryotic Communities and Ecophysiology Prokaryotic Physiology and Biochemistry Applied Bacteriology and Biotechnology Human Microbiology Actinobacteria Firmicutes Alphaproteobacteria and Betaproteobacteria Gammaproteobacteria Deltaproteobacteria and Epsilonproteobacteria Other Major Lineages of Bacteria and the Archaea

Download or read book Biomass Conversion written by Chinnappan Baskar and published by Springer Science & Business Media. This book was released on 2012-05-08 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: The consumption of petroleum has surged during the 20th century, at least partially because of the rise of the automobile industry. Today, fossil fuels such as coal, oil, and natural gas provide more than three quarters of the world's energy. Unfortunately, the growing demand for fossil fuel resources comes at a time of diminishing reserves of these nonrenewable resources. The worldwide reserves of oil are sufficient to supply energy and chemicals for only about another 40 years, causing widening concerns about rising oil prices. The use of biomass to produce energy is only one form of renewable energy that can be utilized to reduce the impact of energy production and use on the global environment. Biomass can be converted into three main products such as energy, biofuels and fine chemicals using a number of different processes. Today, it is a great challenge for researchers to find new environmentally benign methodology for biomass conversion, which are industrially profitable as well. This book focuses on the conversion of biomass to biofuels, bioenergy and fine chemicals with the interface of biotechnology, microbiology, chemistry and materials science. An international scientific authorship summarizes the state-of-the-art of the current research and gives an outlook on future developments.
