Bioprocessing Of Biofuels

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.

The major issues relating to environmental sustainability such as a heavy dependency on fossil fuels, increased greenhouse gas emissions, pollution, global warming and climate change have prompted many efforts around the globe to seek alternative energy sources that have negligible environmental impacts and societal benefits. There is an immense interest in biofuels research throughout the world owing to its massive potential to address environmental concerns. Biofuels have the capacity to supplement current and future energy demands through being blended with fossil fuels or even replacing them completely as drop-in fuels in automobiles as well as for heating and the power industries. Waste biomass, primarily lignocellulosic biomass (e.g. agricultural crop residues, forestry biomass and energy crops) and microalgae can act as some inexpensive renewable bioresources for the production of biofuels and biochemicals. The prime focus of Bioprocessing of Biofuels is to shed light on this significant process, especially through microbial conversion technologies to recover and transform the inedible polysaccharides into hydrocarbon biofuels and bioenergy. The book offers introductory coverage of the most crucial topics as follows: A systematic overview of the state-of-the-art in the production and utilization of biofuels Categorical bioprospecting of bioresources for biofuel production Biomass pretreatment and enzymatic saccharification Bioconversion of waste biomass and algae to liquid and gaseous biofuels New developments in microbial fuel-cell technologies Bioprocessing of Biofuels unites topics related to the cutting-edge applications of bioresources and green technologies to reinvigorate biorefineries, positioning them within a competitive energy market. Written to be instantly applicable, this volume offers a reference book for undergraduate and graduate students, scientific investigators and research scholars around the globe working in the areas relating to energy and fuels.

This book discusses various renewable energy resources and technologies. Topics covered include recent advances in photobioreactor design; microalgal biomass harvesting, drying, and processing; and technological advances and optimised production systems as prerequisites for achieving a positive energy balance. It highlights alternative resources that can be used to replace fossil fuels, such as algal biofuels, biodiesel, bioethanol, and biohydrogen. Further, it reviews microbial technologies, discusses an immobilization method, and highlights the efficiency of enzymes as a key factor in biofuel production. In closing, the book outlines future research directions to increase oil yields in microalgae, which could create new opportunities for lipid-based biofuels, and provides an outlook on the future of global biofuel production. Given its scope, the book will appeal to all researchers and engineers working in the renewable energy sector.

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.
