This editor believes the public finally understands that bioenergy should be a critical new 39 component of our world’s future energy supply. While this new enlightenment might have 40 come from bioenergy’s environmentally friendly attributes and its renewable and sustain- 41 able nature, the reality is that the primary driver has been both the high cost of energy, 42 led recently by petroleum products, and the unique climatic changes such as local weather 43 events and reports of melting of ancient glaciers. I believe that much of the public under- 44 stands the primary cause of these changes is the growing demand for fossil fuels for heat- 45 ing and transportation needs driven by both population increases and dramatic economic 46 development around the globe. This increased demand, as well as global politics, has 47 impacted the costs for these energy products. At the same time, increased use of fossil fuels 48 has been liberating unprecedented levels of CO and other greenhouse gasses (GHGs) 49 2 that must be impacting the global climate. As a result, the world is looking for alternative 50 solutions. Renewable energy is one of the leading options as long as it is pursued in a sus- 51 tainable fashion. Of course, renewable energy has numerous sources, including wind, solar, 52 geothermal, ocean currents/tides, and bio-based energy. The latter category of renewable 53 energy is centered primarily on use of green plant matter, i. e.

Enzymes such as cellulases have been applied as tools for research and development and in almost every industrial sector including agriculture, food, beverages and animal feed, pulp and paper, textile. Cellulases is a general term that encompasses multiple enzymes that work in synergism for cellulose degradation. This book examines the production, applications and health benefits of cellulase. Chapter One describes the isolation, screening, diversity and cellulase production of microorganisms including their applications. Chapter Two discusses the factors affecting production of cellulase enzyme by microorganisms, the potential of indigenous microorganism for the bio-augmentation process of biosolids and occurrence of catabolite repression phenomenon of cellulase production during the enzymatic degradation of biosolids. Chapter Three gives an overview on cellulase microorganism producers, cellulolytic components and mechanism of action, with a focus on fungal enzymes of Trichoderma reesei, since they are predominant on the commercial cocktails used for 2G ethanol production. Chapter Four addresses substrate factors related to enzymatic hydrolysis of cellulose and lignocellulosic materials.

Bioethanol has been recognized as a potential alternative to petroleum-derived transportation fuels. Even if cellulosic biomass is less expensive than corn and sugarcane, the higher costs for its conversion make the near-term price of cellulosic ethanol higher than that of corn ethanol and even more than that of sugarcane ethanol. Conventional process for bioethanol production from lignocellulose includes a chemical/physical pre-treatment of lignocellulose for lignin removal, mostly based on auto hydrolysis and acid hydrolysis, followed by saccharification of the free accessible cellulose portions of the biomass. The highest yields of fermentable sugars from cellulose portion are achieved by means of enzymatic hydrolysis, currently carried out using a mix of cellulases from the fungus Trichoderma reesei. Reduction of (hemi)cellulases production costs is strongly required to increase competitiveness of second generation bioethanol production. The final step is the fermentation of sugars obtained from saccharification, typically performed by the yeast Saccharomyces cerevisiae. The current process is optimized for 6-carbon sugars fermentation, since most of yeasts cannot ferment 5-carbon sugars. Thus, research is aimed at exploring new engineered yeasts abilities to co-ferment 5- and 6-carbon sugars. Among the main routes to advance cellulosic ethanol, consolidate bio-processing, namely direct conversion of biomass into ethanol by a genetically modified microbes, holds tremendous potential to reduce ethanol production costs. Finally, the use of all the components of lignocellulose to produce a large spectra of biobased products is another challenge for further improving competitiveness of second generation bioethanol production, developing a biorefinery.
