Download or read book Microbial Cogeneration of Biofuels written by Matthew John Scholz and published by . This book was released on 2011 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fields of biodiesel and bioethanol research and development have largely developed independently of one another. Opportunities exist for greater integration of these processes that may result in decreased costs of production for both fuels. To that end, this work addresses the use of the starches and glycerol from processed algal biomass as substrates for fermentation by the yeastsSaccharomyces cerevisiaeandPachysolen tannophilus, respectively. Ethanol producers commonly employ the former yeast for ethanol production and include the latter yeast among candidate species for cellulosic ethanol production. A simple 95% ethanol extraction at 70°C followed by sulfuric acid hydrolysis at 121°C and 2 atm proved a sufficient pretreatment forS. cerevisiaefermentation of starch fromChlamydomonas reinhardtiimutantcw15.The maximum rate of ethanol production was observed as 14 mL/g-h and a maximum concentration of 0.9±0.01% (m/v) was observed by 28 hours. Some starch appeared invulnerable to hydrolysis.P. tannophilusfermentation of glycerol, both independently and among mixed substrates, was likewise demonstrated. It was found that glucose consumption preceded that of glycerol and xylose, but that the latter two substrates were consumed concurrently. Under aerobic, batch conditions, the maximum specific growth rate of the species on a 2% glycerol substrate was observed as 0.04/hr and the yield coefficient for conversion of glycerol to ethanol was 0.07 g/g. While the maximum observed concentration of ethanol in the glycerol-only fermentation was 0.1% m/v, that in mixed media containing 2% each glucose, xylose, and glycerol was 1.5%. Also investigated here was the flocculation of a mutant species of the algaeC. reinhardtiiby a combination of methanol and calcium. Algae harvest is typically an energy-intensive process, but the technique demonstrated here is not. Complete flocculation of cells was observed with only 5 minutes of mixing and less than 10 minutes of settling using 12 mM CaCl2and 4.6% methanol. Ethanol was observed to operate in the same capacity, intimating another area in which yeast bioethanol and algal biodiesel processes might enable one another. During growth, either an inhibitor of flocculation was produced or a facilitator was consumed.

Download or read book Engineering of Microorganisms for the Production of Chemicals and Biofuels from Renewable Resources written by Guillermo Gosset and published by Springer. 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.
