This book presents the chemical properties of lignocellulosic fibers, knowledge of which is essential for innovation and sustainable development of their transformation. Thermochemical transformation of wood and other lignocellulosics is presented to highlight its volatile, liquid and solid products and their novel applications. Forest biorefinery is described to emphasize the new products from lignocellulosic constituents, both structural (cellulose, hemicelluloses and lignins) and those extraneous to cell walls-extractives. New developments in cellulose technology related to nanocellulose are discussed in relation to new applications. Industrial lignins are presented in detail, both in terms of extraction procedures from spent liquors and structural characterization of the isolated lignins. Application of lignocellulosic biopolymers in new composite materials, or in biomaterials for medicinal purposes, and in solid wood preservation, are described. The example of an industrial biorefinery installed in southwestern France more than 40 years ago is presented.

This volume describes recent advances in the bioconversion of lignocellulosics. It starts with two articles on genetics and properties of cellulases and their re- tion kinetics and mechanisms. The cost of cellulases has been a hindrance to large scale use of enzymatic hydrolysis. Two articles on cellulase production by submerged fermentation and by solid state fementation are included to describe the state of the art in this area. Dilute acid hydrolysis of cellulose continues to be of interest as well as potentially useful. The most recent advances in this area is also covered. A great deal of progress has been made in genetic engineering for improved regulation of xylose fermentation by yeasts. An article on genetically engineered Saccharomyces for simulteaneous fermentation of glucose and xylose describes the importance advances made in production of fuel ethanol from lignocellulosic biomass. In recent years, there has been increasing interests in recycling and the reuse of scrap paper as well as environment considerations. A contribution is presented which describes the research perspectives in that area. Finally, recent advances in the use of lignocellulosic biomass for the p- duction of ethanol and organic acids are presented in two articles. Renewable resources are inevitably of great importance in the years to come. There is a never-ending search for better living conditions for human beings. The more resource materials can be recycled, the richer we will be.

Lignocellulosic Biomass Production and Industrial Applications describes the utilization of lignocellulosic biomass for various applications. Although there have been numerous reports on lignocellulosic biomass for biofuel application, there have been very few other applications reported for lignocellulosic biomass-based chemicals and polymers. Therefore, this book covers all of the possible lignocellulosic biomass applications. Besides describing the different types of biofuel production, such as bioethanol, biobutanol, biodiesel and biogas from lignocellulosic biomass, it also presents various other lignocellulosic biomass biorefinery applications for the production of chemicals, polymers, paper and bioplastics. In addition, there are chapters on valorization of lignocellulosic materials, alkali treatment to improve the physical, mechanical and chemical properties of lignocellulosic natural fibers, and a discussion of the major benefits, limitations and future prospects of the use of lignocellulosic biomass.

This book introduces fundamentals of enzymatic processes, various renewable energy resources and their pretreatment processes. It presents in-depth review of extremophilic enzymes (e.g., Cellulases, Xylanases, Lytic Polysaccharide Monooxygenases, Amylases, Ligninases, Pectinases, Esterases, and Chitinases) which can be used in several biotechnological processes. In addition, the authors present expert knowledge on how to engineer enzymes for enhanced conversion of lignocellulosic feedstocks to biofuels.Extremozymes play important roles in many kinds of bioprocessing e.g., in conversion of non-food biomass into usable power. Existing enzymatic technologies, including hydrolysis of lignocellulose into sugars, have several limitations such as they have very slow enzymatic hydrolysis rates, yields low products, requires high dosages of enzymes, and are sensitive to microbial contamination problems. These limitations could be overcome using extremophilic enzymes.

This book comprehensively summarizes important aspects of research in the active field of lignocellulosic (polymer) composites, including polymer materials from or containing cellulose, hemicellulose and lignin. It describes how these materials can be produced from forest products and natural fibers from sources such as jute, flax, sisal, and many more, and even from agricultural residues (like wheat straw, corn stover, or sugarcane bagasse). In times of high demand for renewable green materials, lignocellulosic materials from organic matter produced by trees, shrubs and agricultural crops present a highly attractive feedstock. The international authors explain different treatment and fabrication methods for the production of lignocellulosic materials. Other chapters address the properties of these green materials or illustrate specific applications, ranging from food packaging and household products to adsorbents and even conductive polymer composites. In this way, this book offers a broad and comprehensive overview over the entire field of lignocellulosic composite materials.

Lignocelluloses as agricultural, industrial, forest residuals, food-processing waste or paper wastes have the potential to serve as low-cost and abundant source of raw materials for the production of different biochemicals which can serve as future energy sources. These potentially valuable materials consist of sugars and lignin that can be converted via biological pathway into many valuable bioproducts and biochemicals. Two valuable biochemicals that can be fermented from sugars derived from lignocellulosic biomass are xylitol and ethanol. Compared with glucose, which can be readily fermented by well studied yeast (Saccharomyces cerevisiae) and bacterial (Zymomonas mobilis) strains, xylose is more difficult to ferment because a lack of industrially suitable microorganism able to rapidly and efficiently metabolize xylose in presence of six carbon sugars. In order to keep biochemicals production cost at minimum, all the sugars naturally present in lignocellulosic biomass must be converted into biofuels and biochemicals. The need for a microorganism that can utilize all the sugars present in lignocellulosic biomass and to tolerate the inhibitory compounds generated during biomass pretreatment is therefore apparent. One of the yeast which was identified in our labs as being capable of rapid assimilation and catabolism of five and six carbon sugars (arabinose, galactose, glucose, xylose and mannose) is Rhodotorula mucilaginosa strain PTD3, an endophytic yeast of hybrid poplar Populus trichocarpa x deltoids. PTD3 was found to be capable of producing xylitol from xylose, ethanol from glucose, galactose, and mannose, and arabitol from arabinose. Glucose-acclimated PTD3 produced enhanced yields of xylitol (67% of theoretical yield) from xylose and of ethanol (84, 86, and 94% of theoretical yield, respectively) from glucose, galactose, and mannose. Additionally, this yeast was capable of metabolizing high concentrations of mixed sugars (150 g/L), with high yields of xylitol (61% of theoretical yield) and ethanol (83% of theoretical yield). A 1:1 glucose:xylose ratio with 30 g/L of each during double sugar fermentation did not affect PTD3's ability to produce high yields of xylitol (65% of theoretical yield) and ethanol (92% of theoretical yield). Surprisingly, the highest yields of xylitol (76% of theoretical yield) and ethanol (100% of theoretical yield) were observed during fermentation of sugars present in the lignocellulosic hydrolysate obtained after steam pretreatment of a mixture of hybrid poplar and Douglas fir. Also, PTD3 demonstrated the ability to tolerate higher concentrations of inhibitors during xylitol and ethanol production compared to other yeasts described in the literature. Concentration of up to 5 g/L of furfural stimulated production of xylitol to 77% of theoretical yield (10% higher compared to the control) by PTD3. Xylitol yields produced by this yeast were not affected in a presence of 5-HMF at concentrations of up to 3 g/L. At higher concentrations of furfural and 5-HMF, xylitol and ethanol yields were negatively affected. The higher the concentration of acetic acid present in a media, the higher the ethanol yield approaching 99% of theoretical yield (15% higher compared to the control) was produced by the yeast. At all concentrations of acetic acid tested, xylitol yield was lowered. PTD3 was capable of metabolizing concentrations of 5, 15, and 5 g/L of furfural, 5-HMF, and acetic acid, respectively. The high xylitol and ethanol yields obtained and significant resistance to the toxicity of the inhibitors indicate the great potential of the tested strain as a realistic candidate for industrial scale biofuels and biochemicals production from lignocellulose. After assessing these PTD3's abilities to ferment glucose and xylose and to tolerate the fermentation inhibitors, the next step was to determine the optimum pretreatment conditions which will cause the production of a unique concentration of fermentation inhibitors that would enhance fermentation of xylitol and ethanol by yeast Candida guilliermondii. Based on concentrations of inhibitors present, hydrolysates obtained after steam pretreatment of five lignocellulosic feedstocks (mixed wood, hybrid poplar, Arundo donax, switchgrass, and sugarcane bagasse) were evaluated in terms of enhanced xylitol and ethanol production. In addition, for deeper understanding of the effect of process inhibitors on the overall xylitol and ethanol yields after fermentation, hybrid poplar feedstock was selected and pretreated at different severity conditions using steam pretreatment. Customizing the steam pretreatment conditions for production of fermentation inhibitors at unique concentration can be used as a novel approach of improving xylose to xylitol and six carbon sugars to ethanol conversion by Candida guilliermondii.

This book is intended to give readers an appreciation of what the future holds, as cutting-edge technologies in synthetic biology and pathway engineering and advanced bioprocessing development pave the way for providing goods and services to benefit humankind that are based on the synergy of two biomasses - i.e. of what a renewable feedstock could yield and an infinite microbial biomass could provide in terms of enzymes and biocatalysts. This 13-chapter book, with an introductory treatise on the guiding principles of green chemistry and engineering metrics, brings together a broad range of research and innovation agendas and perspectives from industries, academia and government laboratories using renewable feedstocks that include macroalgae and lignins. In addition, social-economic aspects and the pillars of competitiveness in regional cluster development are explored as we transition from fossil-fuel-based economies to a circular bioeconomy, with chemurgy and green chemistry being implicit to the innovation movement. The bulk of the book covers specific applications including the bioproduction of amino sugars, dicarboxylic acids, omega-3 fatty acids, starch and fermentable sugars from lignocellulosic materials, and phenolics as building blocks for polymer synthesis. Enzymatic systems for accessing chiral and special-purpose chemicals, as well as the development of specialized enzymes from macroalgae for biofuel and biochemical production are also addressed. Research gaps, hurdles to overcome in various biological processes, and present achievements in the production of biofuels and biochemicals from lignocellulosic materials are discussed. Going beyond the conventional expectation of discussing the production of drop-in chemicals, the book instead emphasizes how the potential of new chemicals and materials can be harnessed through innovative thinking and research. As such, it provides an invaluable reference source for researchers and graduate students interested in Chemurgy and Green Chemistry, as well as for practitioners in the field of industrial biotechnology and biobased industry. Peter C.K. Lau is a Distinguished Professor at Tianjin Institute of Industrial Biotechnology of the Chinese Academy of Sciences, and an Adjunct Professor at the Departments of Chemistry and Microbiology & Immunology, McGill University, Canada.
