Available in PDF, EPUB and Kindle. Book excerpt: The increase in the amount of glycerin in the market is a burden for all producers, especially those operating in the biodiesel sector: reuse options are in fact limited for the management of this by-product. Glycerol enhancement has therefore become a priority to improve the sustainability of the biodiesel industry. Nevertheless, the multifunctionality of glycerol makes it a promising precursor for different types of production (fuel/biofuel, chemical products). This conversion has therefore become a subject of multifaceted research that requires an exchange of knowledge across many sectors. In this book, different disciplines (chemistry, biology, engineering, etc.) have been taken into consideration to propose an interdisciplinary point of view on different aspects.
Book Synopsis Microbial Conversions of Raw Glycerol by : George Aggelis
Download or read book Microbial Conversions of Raw Glycerol written by George Aggelis and published by Nova Science Publishers. This book was released on 2009 with total page 0 pages. 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.

Book Synopsis Microbial Factories by : Vipin Chandra Kalia
Download or read book Microbial Factories written by Vipin Chandra Kalia and published by Springer. This book was released on 2016-02-16 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the efforts made by distinguished scientific researchers world-wide to meet two key challenges: i) the limited reserves of polluting fossil fuels, and ii) the ever-increasing amounts of waste being generated. These case studies have brought to the foreground certain innovative biological solutions to real-life problems we now face on a global scale: environmental pollution and its role in deteriorating human health. The book also highlights major advances in microbial metabolisms, which can be used to produce bioenergy, biopolymers, bioactive molecules, enzymes, etc. Around the world, countries like China, Germany, France, Sweden and the US are now implementing major national programs for the production of biofuels. The book provides information on how to meet the chief technical challenges – identifying an industrially robust microbe and cheap raw material as feed. Of the various possibilities for generating bioenergy, the most attractive is the microbial production of biohydrogen, which has recently gained significant recognition worldwide, due to its high efficiency and eco-friendly nature. Further, the book highlights factors that can make these bioprocesses more economical, especially the cost of the feed. The anaerobic digestion (AD) process is more advantageous in comparison to aerobic processes for stabilizing biowastes and producing biofuels (hydrogen, biodiesel, 1,3-propanediol, methane, electricity), biopolymers (polyhydroxyalkanoates, cellulose, exopolysaccharides) and bioactive molecules (such as enzymes, volatile fatty acids, sugars, toxins, etc.) for biotechnological and medical applications. Information is provided on how the advent of molecular biological techniques can provide greater insights into novel microbial lineages. Bioinformatic tools and metagenomic techniques have extended the limits to which these biological processes can be exploited to improve human welfare. A new dimension to these scientific works has been added by the emergence of synthetic biology. The Big Question is: How can these Microbial Factories be improved through metabolic engineering and what cost targets need to be met?
Download or read book Glycerol written by Claudio J. A. Mota and published by Springer. This book was released on 2017-06-15 with total page 116 pages. Available in PDF, EPUB and Kindle. 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.
Book Synopsis Production of 1,3-propanediol from Glycerol Under Haloalkaline Conditions by Halanaerobium Hydrogeniformans by : Daniel William Roush

This book was released on 2013 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: "With increased demands around the world to make modern lifestyles more environmentally friendly, the chemical commodity market has rapidly shifted. Through new technologies in chemical production, certain high value products have oversaturated the market and have become high-volume, low value waste products. The expansion of biodiesel production offers a prime example; high volumes of glycerol byproduct from this process have shifted glycerol from a high priced commodity to a common waste product. A number of microorganisms are known to synthesize the polymeric precursor 1,3-propanediol from glycerol; however, crude glycerol from biodiesel production creates a harsh environment for most microbes, and must go through expensive pre-treatment steps to lower alkaline pH values and salt concentrations before it can be considered a suitable feedstock. Halanaerobium hydrogeniformans has been identified to convert glycerol into 1,3-propanediol under haloalkaline conditions. Samples were grown over five days at pH 11 and at 7% (w/v) NaCl. The growth medium was amended with vitamin B12 to stimulate 1,3-propanediol production. HPLC analysis indicated statistically significant production of 1,3-propanediol, with the vitamin B12 amended bottles having a significant increase in 1,3-propanediol production compared to glycerol-only cultures. Data indicated a 0.6mol/mol conversion for vitamin B12 amended samples, while glycerol-only cultures had a conversion rate of 0.32mol/mol. H. hydrogeniformans, and potentially other haloalkaliphilic bacteria, provides a unique opportunity to develop new chemical processes that can overcome traditional problems and increase profitability by reducing the need for pH neutralization and dilution of residual salts in wastes such as crude glycerol"--Abstract, page iv.
Book Synopsis Engineering of Microorganisms for the Production of Chemicals and Biofuels from Renewable Resources by : Guillermo Gosset

This book was released on 2017-01-26 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews state of the art regarding strategies for generating and improving microbial strains designed for utilizing renewable raw materials. It discusses methods for genetically engineering of thermophilic bacteria, Saccharomyces cerevisiae, Escherichia coli and Zymomonas mobilis, as well as approaches for obtaining useful products from these renewable raw materials based on biotechnological processes using microbes to chemically transform them. However, the efficient transformation of lignocellulosic biomass or glycerol to useful products represents a major challenge: Biomass has to be treated physically and chemically to release a mixture of sugars that potentially can be employed by the microbial production strains. These hydrolytic treatments result in diverse toxic compounds being generated and released, that negatively impact strain performance. Furthermore, most of the commonly used industrial microbes do not have the natural capacity to efficiently utilize and transform the generated sugar mixtures or glycerol. The microbial species reviewed in this book possess particular advantages as production strains and are currently employed for the synthesis of numerous biofuels and chemicals. The book reviews the general and strain-specific genetic engineering strategies for the improvement of sugar mixtures and glycerol catabolism. The issue of lignocellulosic hydrolysate toxicity is addressed in several chapters, where genetic engineering and adaptive laboratory evolution strategies are reviewed and discussed. The objective of this book is to provide the current knowledge regarding strategies for the generation and improvement of microbial strains designed for the transformation of renewable raw materials into useful products. This book aims to become a reference for researchers and students working in this field.

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.

Download or read book Bioconversion of Crude Glycerol to Biofuels and Value-added Bioproducts written by Md. Shafiqur Rahman and published by . This book was released on 2017 with total page pages. 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.
