Available in PDF, EPUB and Kindle. Book excerpt: Increasing demand and the rising cost of fossil fuels, as well as a concern for global climate change have shifted global efforts to utilize renewable resources for the production of a 'greener' energy replacement. Biodiesel, a renewable fuel produced by transesterification of animal fats and vegetable oils, generates about 10% (v/v) of crude glycerol as a core by-product. Consequently, the recent booming of biodiesel industry all over the world has generated a large amount of crude glycerol, creating an oversupply problem. The economic feasibility of the biodiesel industry has been crucially affected due to a high volume (by worldwide surplus) of crude glycerol generated from the biodiesel production process. Consequently, with the increasing number of biodiesel production plants, a large number of glycerol production plants can be expected to be shut down within a few years due to the price drop that will result from the oversupply of glycerol. Therefore, this abundance of glycerol provides an opportunity for the development of new commercial uses. Glycerol, a core by-product of biodiesel production has become an inexpensive and easily obtainable product for which new applications have to be discovered. At present, there is a lack of microorganisms which can efficiently convert crude glycerol to value-added bio-products. The new isolate of bacteria that would permit screening, isolation and over-expression of enzyme would help overcome these challenges. Thus, this research is to identify novel bacterial strains which are capable of efficiently converting glycerol aerobically, and improve the strains for large scale production of value-added products. In Chapter 2 and 3, this study shows a number of bacterial strains isolated from environmental consortia were screened for their capability of converting low or negative-value biodiesel-derived crude glycerol to value-added products. Primarily, an aerobic batch biotransformation process was carried out to observe the kinetics of glycerol dehydrogenase (GDH) activity, bio-product formation and glycerol utilization. Therefore, the major bio-product obtained from this biotransformation of glycerol was 2,3-butanediol (2,3-BD) with minor co-products including acetoin, 1,3-propanediol (1,3-PDO) and acetate. In this study, three bacterial species Klebsiella pneumoniae, K. variicola and Serratia liquefaciens newly isolated from soil and paper mill waste were the highest producers of 2,3-BD. The novel strains K. pneumoniae SRP2 and, K. variicola SRP3 were used to construct a co-culture, capable of simultaneously converting crude glycerol to concurrently produce up to 27.87 g/L of 2,3-BD, yielding 0.73g 2,3-BD per gram glycerol (0.73g/g) using 37.0 g/L glycerol under aerobic conditions in batch culture, showing great potential for biotransformation bioprocess. Therefore, an attempt has been made to produce a major product 2,3-butanediol (2,3-BD) from glycerol as a sole carbon source using newly isolated novel bacterial strains Klebsiella variicola SRP3 and K. pneumoniae SRP2 in a series of batch and fed-batch processes under aerobic process. These studies also compare the bacterial cell biomass, bio-products and a key enzyme glycerol dehydrogenase (GDH) production of K. variicola SRP3 and K. pneumoniae SRP2 isolated from paper mill waste when grown in aerobic condition. The incubation temperature, pH, glycerol concentration and nitrogen sources were the most important factors ruling the GDH. This study also revealed that an increased GDH activity led to a substantially enhanced production of 2,3-BD as a principal product with 1,3-propanediol (1,3-PDO), acetoin and acetate as minor. In Chapter 4-6, the studies of high production of 2,3-butanediol (2,3-BD) from pure and biodiesel derived crude glycerol using an ethyl methanesulfonate (EMS) mutant K. pneumoniae SRM2, and two adapted mutants K. variicola SRM3 and K. variicola SW3 developed from the newly isolated wild type strains K. pneumoniae SRP2 and K. variicola SRM2 respectively are reported. However, as stated in Chapter 4, an adapted mutant strain K. variicola SRM3 withstanding 200 g/L glycerol could efficiently convert glycerol to 29.87 g/L 2,3-BD and 7.08 g/L acetoin from 50.0 g/L glycerol in a batch culture, and an acidic initial pH (pH 5.0) led to enhanced 1.3-fold increased GDH activity of 721.5 units/mg protein from 558.2 units/mg protein.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable forms of energy are of significant interest in today's economies. Biofuel is a renewable fuel produced by biological means. Biofuel is very useful because it does not have a finite supply, and it produces fewer pollutants than fossil fuels. Recently, there is a serious concern about future of fossil-based fuels due to increasing price of crude oil around the world, depletion of its sources, several important environmental issues (greenhouse effect and global warming) and increasing energy demands. Thus, this situation has imposed researchers for further exploring the renewable energy sources to produce environmentally friendly fuel that not cause any pollution to the atmosphere. Additionally, nowadays, supplies like plants, organic wastes, and agricultural products are often used to produce biofuel. Until now, bioethanol and biodiesel are the most widely produced and used as biofuel. Biodiesel-derived crude glycerol and lignocellulosic (from cell walls of woody plants) biomass are two attractive low-cost renewable resources for biofuel production. Efficient and cost-effective production of biofuel from these sources through biotechnological methods depends on the development of a suitable bioconversion process. The main aims of this study were to i) isolate and characterize the novel as well as highly efficient cellulase or glycerol dehydrogenase (GDH) producing bacterial strains, and ii) optimize the enzyme production parameters during fermentation. These strains could be considered for the biorefinery industry for hydrolysis of lignocellulosic biomass or bioconversion of glycerol so as to accelerate biofuel commercialization. In this research project, three potential glycerol metabolizing strains of Serratia sp. were isolated from paper mill waste of Resolute Forest Products, Thunder Bay, Ontario, Canada. The glycerol bioconversion abilities of the promising strain S. proteamaculans SRWQ1 were analyzed ii using crude glycerol (byproduct from biodiesel production) as the sole carbon source. During shake flask fermentation under aerobic conditions at an optimal incubation temperature of 25°C, the strain SRWQ1 used 98% of the crude glycerol and produced 18.43 ± 1.55 g/L 2,3-butanediol (BDO) and 8.38 ± 0.76 g/L acetoin, with yields of 0.4 and 0.06 g/g, respectively. When the culture medium (minimal salt medium) was supplemented with 50 g/L of glycerol as the sole carbon source, and 5 g/L yeast extract and 5 g/L peptone as the nitrogen sources, the maximum glycerol dehydrogenase (DGH) activity was 408.69 ± 0.069 U/mg protein. The incubation temperature, pH, glycerol concentration and nitrogen sources are the most important factors ruling the GDH activity. Slightly acidic initial pH (pH 6.0) led to enhanced GDH activity and biomass production. This is the first report that S. proteamaculans species can efficiently convert glycerol to produce green products 2,3-BDO and acetoin. Twenty cellulase-producing bacterial strains were isolated from Kingfisher Lake, Ontario, Canada, and screened for cellulase activity using the carboxymethyl cellulose (CMC) agar plate assay. Isolates showing large halos of depolymerization were further assayed to quantify enzyme production ability and identified by using 16S rDNA sequence analysis. The molecular weight of crude cellulase samples was determined ∼50 kDa with sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). The Bacillus strain IM7 showed the highest carboxymethyl cellulase (CMCase) activity (17.7 ± 0.17 IU/mL) after 48 h of incubation at a yeast extract concentration of 15 g/L. A temperature of at 30°C and pH 5.0 were the optimal conditions for cellulase production. The highest activity (24.59 ± 0.09 IU/mL) was recorded when the culture medium was supplemented with 2% mannose as a co-substrate. The increased glucose content by using mannose in the hydrolysate process resulted in the dramatic increase in enzyme activity.

Book excerpt: This book is aimed at providing a concise discussion on the use of glycerol as a renewable raw material for the chemical industry. With the increasing use of biodiesel produced from oils and fats, there is a surplus of glycerol in the world. This abundant and rather cheap raw material can be transformed in commodities and specialty chemicals, as well as in fuels. The book describes the main processes of chemical transformation of glycerol, highlighting those that are currently in commercial use and pointing out potential processes to be used in the future. The first chapter introduces the concept of biofuel and briefly describes the production of biodiesel. It also highlights glycerol as the main byproduct of biodiesel synthesis and presents some numbers regarding the world production of glycerol. The second chapter shows the common uses of glycerol and addresses the point whether or not they can drain the large amounts of glycerol produced from biodiesel. The chapter addresses pros and cons of each use. The third chapter covers the main biotechnological processes of glycerol transformation. The fourth chapter thoroughly describes the main thermochemical processes to transform glycerol into commodities, products that will be further used in the chemical industry to produce polymers, for instance. The fifth chapter covers the production of glycerol derivatives of high added-value. The sixth chapter addresses the use of glycerol in the context of a biorefinery. The main idea is to show that many of the processes described in the previous chapters could be entirely green, using exclusively renewable raw materials.

Available in PDF, EPUB and Kindle. Book excerpt: Glycerol is a simple carbon source than can be easy assimilated by numerous eukaryotic and prokaryotic microorganisms. However, this compound had been neglected as substrate for microbial fermentations for many years due mainly to its high cost. Nevertheless, recent developments in the fuel market, led to the production in large scale of biodiesel derived from vegetable oil, reversed this situation. Currently glycerol is available in large quantities in the biodiesel production units. This industry produces enormous quantities of glycerol as a by-product, during transesterification process of the oil with methanol or ethanol. Therefore, glycerol turns into an attractive feedstock. Biotechnology provides a broad range of methods for the valorisation of raw glycerol. Important commodities and high-added value products of industrial interest, such as organic acids, bioplastics, polyunsaturated fatty acids, carotenoids etc could be produced from raw glycerol. Glycerol can also be recycled after its conversion into microbial triacylglycerols and then to biodiesel. In this book, the biochemical pathways of glycerol metabolism in prokaryotic and eukaryotic cells cultivated under various conditions are discussed. The various methods, proposed so far in the international literature for the valorisation of glycerol by biotechnological means, are shown and discussed by using scientific and technological criteria. Evaluation of the economic viability of the 1,3-propanediol production processes is also presented. All chapters (research articles and reviews) were reviewed by experts. Although the examples presented are, doubtless, the more important, there are also a lot of other applications based on raw glycerol.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Crude glycerol is a major by-product of the biodiesel industries. For every 100 kg of biodiesel produced, approximately 10 kg of the byproduct glycerol is generated. With the large increase in biodiesel production, there is a glut in the glycerol produced. Presently crude glycerol is purified to its purer marketable form, burnt as a fuel or mixed with animal feed. However, none of these options contribute considerable revenues to the concerned biodiesel industry. Additionally, some of these routes are not environmentally friendly. It has thus become imperative to find ways to convert crude glycerol to some value-added products. Bioconversion of crude glycerol to microbial lipids is one possible way to valorize it. However, impurities like methanol, salts and soap present in crude glycerol inhibit the growth of microbes used for such conversions. The research work carried out in this thesis addressed these issues and developed tangible alternatives to overcome these problems. Initially the possible use of a heterogeneous catalyst Calcium oxide (CaO) attached to support alumina (Al2O3) for the production of biodiesel was studied. We found that the use of such a catalyst improves the purity of biodiesel and the glycerol produced. Crude glycerol obtained using such insoluble catalysts contained lower levels of impurities and can be converted relatively easily to other useful products. With CaO anchored on Al2O3 as catalyst, the purity of biodiesel and glycerol were found to be 97.66% and 96.36% respectively. The unanchored heterogeneous catalyst CaO resulted in purities of 96.75% and 92.73% respectively. As the byproduct glycerol containing smaller amount of impurities, the use of anchored heterogeneous catalyst is recommended. The potential use of ash from various sources as a cheap alternative heterogeneous catalyst was also studied. With the use of ash from birch bark and fly ash from wood pellets as catalysts, biodiesel and glycerol with purity in the ranges of 88.06%-99.92% and 78.18%-88.23% respectively were obtained. Since such catalysts are cheap and reusable, their application can reduce expenses and the use of environmentally unsafe compounds. The crude glycerol used in all experiments was obtained from a biodiesel producer in Ontario (Canada). It was found to contain 44.56 wt.% glycerol and many impurities including 13.86 wt.% methanol, 32.97 wt.% soap and 4.38 wt.%. After the characterization of the sample it was converted to microbial lipids using an oleaginous yeast Rhodosporidium toruloides ATCC 10788. When this strain was grown on crude glycerol, double the biomass (21.16 g/L) and triple the lipid concentration (11.27 g/L) was obtained compared to growth on pure glycerol media. The capacity of this strain to grow on crude glycerol with high levels of impurities and produce large amounts of lipids proves its robustness. Investigation of the effect of individual components on the lipid production ability of this strain showed it to be capable of using soap as a sole carbon source. This was also the reason for enhanced lipid production even in the presence of other impurities present in crude glycerol. The lipids obtained were rich in oleic acid (47.16%), a mono-unsaturated fatty acid (MUFA). Feedstock rich in MUFA are considered suitable for biodiesel production. Thus, the process of conversion of crude glycerol to microbial lipids can be integrated to existing biodiesel plants. This will help in the management of crude glycerol produced during biodiesel production, save transportation and disposal costs and contribute to the revenues of such industries.

This book was released on 2009 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work was carried out to evaluate the optimum conditions for synthesis of 1,3-propanediol from crude glycerol by an electrochemical technique. The experiment of glycerol reforming was separated into three parts. The first part was studied the glycerol reforming from synthetic and purified crude glycerol to 1,3- propanediol by the electrochemical technique. It was found that the optimum conditions; applied current intensity of 4.5 A, an initial pH of 1 set by H2SO4, 2.93 g/l NaCl, electrical charge of 100 Ah/l with Pt electrode; provided the yield of 1,3- propanediol by using synthetic and crude glycerol of 40.81% and 4.76%, respectively. For the second part, the purification of crude glycerol from biodiesel plant under strong acid conditions by using the chemical process was observed. The pH of crude glycerol was adjusted to 2.2 by 1.19 M H3PO4 and extracted glycerolrich layer solution with n-C6H14. After that, glycerol-rich layer neutralized with 12.50 M KOH and extracted with excess C2H5OH could provide the purity of glycerol around 97.92 % with low contaminant levels ash, matter organic non glycerol and water around 0.01, 0.79 and 1.28% w/w, respectively. As studied in the final part of the purified crude glycerol reforming to 1,3-propanediol, the optimum conditions of applied current intensity of 6 A, an initial pH of 1, and an electrical charge of 184.61 Ah/l with Pt electrode could provide the yield of 1,3-propanediol about 26.31%.

This book was released on 2014-04-01 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Renewable energy sources and biofuel, including biodiesel, have been gaining increasing attention recently as a replacement for fossil fuels. However, their implementation in the general market depends on making these fuels more competitive. A convenient way to lower the cost of biofuel is to use the by-products as a potential source of energy, rather than treating them as waste. The industrial conversion of renewable resources into useful compounds, namely bio-based materials, has been receiving much attention from the environmental point of view. The crude glycerol from biodiesel production represents an abundant and inexpensive carbon source. Glycerol is yielded at about 10% as a by-product during the process of biodiesel production. The global biodiesel market is estimated to reach 39 billion gallons by 2020, growing at an average annual growth of 42%. Therefore, microbial conversion of raw glycerol into value added fermented products were investigated aiming to facilitate the utilization of waste glycerol.
Book Synopsis From Glycerol to Value-Added Products by : Patrick Cognet
Download or read book From Glycerol to Value-Added Products written by Patrick Cognet and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a context where the role of biofuels will continue to grow, it is necessary to take into account the current state of their various manufacturing processes and to anticipate the expansion of the market. Thus, current biodiesel production processes generate a significant amount of glycerol as a by-product (about 100 kg per ton of processed vegetable oil). An explosion of the biodiesel market must integrate the valorization of glycerol whose current market of distribution (cosmetics, drugs, polymers, etc.) is not guaranteed such an expansion. This valuation will contribute effectively to the profitability and sustainability of the processes from which it derives. Glycerol physicochemical and toxicological properties give it the potential to be used as solvent, biolubricant, dispersant, and surfactant, among others. It is also widely used in the food industry as a preservative and sweetener. Beyond these applications, glycerol can also be used as a raw material for a wide range of chemicals. Glycerol is a highly functionalized molecule with specific physico-chemical properties, which can be used in different reactions as a reactant or a building block. For example, glycerol can be used as a starting material for antibiotic production, biosurfactants, organic acid production (lactic, propionic, succinic, citric acid, glyoxylic acid, glyoxalic acid, amino acids, etc.), alcohols (propanediols), glycerol esters, acrolein production, etc. These products can be obtained either through chemical reactions such as acetalization, dehydration, glycerolysis, esterification, etherification, aqueous phase reforming, oxidation, carboxylation, electrochemical routes, or through enzymatic reactions. However, it must be kept in mind that the development of industrial processes relies on the use of crude glycerol from biodiesel production. For that purpose, robust processes involving impurities-insensitive catalysts or pre-purification have to be developed. Finally, the separation of the chemical products obtained after glycerol conversion is also a key step toward the development of viable glycerol-based processes.
