This book presents a review and in-depth analyses of improved biotechnological processes emphasizing critical aspects and challenges of lignocellulosic biomass conversion into biofuels and value-added products especially using extremophiles and recombinant microorganisms. The book specifically comprises extremophilic production of liquid and gaseous biofuels (bioethanol, biobutanol, biodiesel, biohydrogen, and biogas) as well as value added products (e.g. single cell protein, hydrocarbons, lipids, exopolysaccharides, and polyhydroxyalkanoates). The book also provides the knowledge on how to develop safe, more efficient, sustainable, and economical integrated processes for enhanced conversion of lignocellulosic feedstocks to liquid and gaseous biofuels. Finally the book describes how to perform the techno-economical and life-cycle assessments of new integrated processes involving extremophiles. These modeling exercises are critical in addressing any deficiencies associated with the demonstration of an integrated biofuels and value-added products production process at pilot scale as well as demonstration on the commercialization scale.

Cellulosic ethanol biofuel, made from plant waste products or perennial energy crops like switchgrass, offers many advantages over corn starch-derived ethanol, including less land competition and a lower carbon footprint. However, the efficiency of conversion is currently lower and the cost higher due to the recalcitrance of lignocellulosic biomass. A chemical and/or physical pretreatment step is required to overcome recalcitrance, and common pretreatment methods (e.g., acid, steam, and/or depressurization) release microbial inhibitors, including furfural and acetate, into the hydrolysate, lowering the yield of ethanol via fermentation. Furfural is generated via sugar dehydration, and acetate derives from acetylated xylan in hemicellulose. Utilizing a detoxifying strain is one strategy to overcome the inhibitor dilemma. Biological detoxification potentially allows lower process costs compared to chemical or enzymatic detoxification or alternative pretreatment methods aimed at reducing inhibitor generation. One drawback is time. Thus increasing the rate of furfural and acetate detoxification is desirable. While most microbial species can catabolize acetate, most do not possess the furfural catabolic pathway. A novel Pseudomonas putida isolate ALS1267, with a growth rate of 0.25/h in 10 mM minimal furfural medium, was characterized. The genome was sequenced and the furfural pathway cloned into wild-type P. putida KT2400, which cannot metabolize furfural, creating a novel strain with an improved growth rate of 0.34/h in 10 mM minimal furfural medium. Genomic library screening was used to find targets for engineering increased acetate consumption in Escherichia coli. Sixteen plasmid clones were generated, with growth rate increases of 42.6 to 76.9 percent in 10 g/l minimal acetate medium, which is a highly inhibitory concentration for this strain. Clones included an uncharacterized oxidoreductase, transporters and other outer membrane proteins, carbon scavengers, and stress defense mechanisms. Genomic mutants with improved acetate consumption were also generated during selection, with mutations in the gluconeogenesis gene pck promoter, the '5 UTR of the poorly characterized cold-shock gene ynaE, and the global regulator of secondary carbon sources CRP. The second major drawback to biological detoxification is consumption of the sugars to be used to produce ethanol by the detoxifying strain. Elimination of glucose metabolism in E. coli was studied by characterizing fast-growing revertants in strains engineered to be glucose minus. All of the revertants either altered or overproduced the N-acetylglucosamine phosphotransferase system. Deletion of the N-acetylglucosamine transporter stabilized the glucose minus phenotype and prevented the occurrence of fast-growing revertants.

The European Symposium on Computer Aided Process Engineering (ESCAPE) series presents the latest innovations and achievements of leading professionals from the industrial and academic communities. The ESCAPE series serves as a forum for engineers, scientists, researchers, managers and students to present and discuss progress being made in the area of Computer Aided Process Engineering (CAPE). European industries large and small are bringing innovations into our lives, whether in the form of new technologies to address environmental problems, new products to make our homes more comfortable and energy efficient or new therapies to improve the health and well-being of European citizens. Moreover, the European Industry needs to undertake research and technological initiatives in response to humanity's "Grand Challenges", described in the declaration of Lund, namely, Global Warming, Tightening Supplies of Energy, Water and Food, Ageing Societies, Public Health, Pandemics and Security. Thus, the Technical Theme of ESCAPE 21 will be "Process Systems Approaches for Addressing Grand Challenges in Energy, Environment, Health, Bioprocessing & Nanotechnologies".
