Book Description
Clostridium cellulovorans is a strictly anaerobic, cellulolytic bacterium among the most interesting candidates for CBP of lignocellulosic biomass. Recently, a bifunctional aldehyde/alcohol dehydrogenase gene adhE2 from Clostridium acetobutylicum has been overexpressed in C. cellulovorans for n-butanol production from cellulose. However, this recombinant strain produced n-butanol from microcrystalline cellulose at a low titer and yield insufficient for industrial application. In addition, there are two type II restriction modification (RM) systems in C. cellulovorans and currently available plasmids would be digested by C. cellulovorans cell extract even after in vivo methylation, making it difficult to transfer and express genes in C. cellulovorans for further metabolic engineering. Therefore, efficient transformation for developing better recombinant C. cellulovorans for butanol production is urgently required.

Book Description
In summary, C. cellulovorans was metabolically engineered to produce n-butanol and ethanol directly from cellulosic biomass, with the development of its transformation method for the first time. In addition, the engineered C. cellulovorans could produce 1.6 g/L n-butanol directly from cellulose, which is the highest, compared to other wild-type and engineered cellulolytic strains. This project provided a promising platform for the production of biofuel and other value-added products directly from lignocellulosic biomass.

Book Description
Cellulose is only one of the components of biomass, although being the most abundant. To make useful chemicals or materials from cellulose requires as the first step the separation of cellulose from biomass. Various issues of cellulose extraction and its conversion are discussed in the chapters of this book on cellulose, the third and last one of a series of books on cellulose. This conversion of cellulose is an integral part of the biorefinery concept, an effort to derive optimum value from all biomass components, and as such compulsory reading for students and researchers in this area.

Book Description
Converting biomass to biofuels involves hydrolyzing cellulose to sugars using cost-intensive commercial enzymes – an expensive step that makes large-scale production economically non-viable. As such, there is a need for low-cost bioprocessing. This book critically evaluates the available bioprocessing technologies for various biofuels, and presents the latest research in the field. It also highlights the recent developments, current challenges and viable alternative approaches to reduce the overall cost of producing biofuels.

Book Description
Amongst concerns about climate change, energy security decline and depletion of fossil fuels, this book explores the high importance of and interests in alternative energy resources. Many studies have shown that biomass fuels are sustainable, environmentally friendly and can be the most appropriate replacement to the depleting crude oil. Additionally, they can expand green landscapes, create new job opportunities, be directly utilised in standard power systems and improve combustion performance. Biomass fuels can be limited due to production cost and competition with food. Therefore, plant and food wastes play an important role in reducing these costs and recycling dump bio-materials. Production of biofuels from non-food biomass has emerged as a sustainable option to tackle the problems associated with growing demands for energy.

Book Description
Sets the stage for large-scale production of biofuels and bio-based chemicals In response to diminishing supplies as well as the environmental hazards posed by fossil fuels and petrochemicals, interest and demand for green, sustainable biofuels and bio-based chemicals are soaring. Biomass may be the solution. It is an abundant carbon-neutral renewable feedstock that can be used for the production of fuels and chemicals. Currently, biorefineries use corn, soybeans, and sugarcane for bioethanol and biodiesel production; however, there are many challenges facing biorefineries, preventing biomass from reaching its full potential. This book provides a comprehensive review of bioprocessing technologies that use lignocellulosic biomass for the production of biofuels, biochemicals, and biopolymers. It begins with an overview of integrated biorefineries. Next, it covers: Biomass feedstocks, including sugar, starch, oil, and energy crops as well as microalgae Pretreatment technologies for lignocellulosic biomass Hydrolytic enzymes used in biorefineries for the hydrolysis of starch and lignocelluloses Bioconversion technologies for current and future biofuels such as ethanol, biodiesel, butanol, hydrogen, and biogas Specialty chemicals, building block chemicals, and biopolymers produced via fermentation Phytochemicals and functional food ingredients extracted from plant materials All the chapters have been written and edited by leading experts in bioprocessing and biorefining technologies. Contributions are based on a thorough review of the literature as well as the authors' firsthand experience developing and working with bioprocessing technologies. By setting forth the current state of the technology and pointing to promising new directions in research, Bioprocessing Technologies in Biorefinery for Sustainable Production of Fuels, Chemicals, and Polymers will enable readers to move towards large-scale, sustainable, and economical production of biofuels and bio-based chemicals.
