Book excerpt: Cellulase refers to a class of enzymes produced chiefly by fungi, bacteria, and protozoans that catalyse the cellulolysis (or hydrolysis) of cellulose. The enormous potential that cellulases have in biotechnology is the driving force for continuous basic and applied research on these biocatalysts from fungi and bacteria. Cellulases are found in many fields, such as animal feeding, brewery and wine, food, textile and laundry, pulp and paper products. The growing interest toward the conversion of lignocellulosic biomass into fermentable sugars has generated an additional request for cellulases and their related enzymes. This book presents research in the study of cellulase, including biotechnological applications of microbial cellulases; using agro-industrial by-products as raw material for cellulase production; and the enzyme saccharification of cereal crop residues using dilute alkali pre-treatment.

This book was released on 2019-04-26 with total page 218 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cellulase is a key enzyme of industrial interest and plays a crucial role in the hydrolysis of cellulose, a prime component of plant cell walls. Cellulase covers a broad area in the global market of industrially important enzymes and it is considered as the third largest industrial enzyme globally. Additionally, cellulase contributes about 20% of the total enzyme market globally because of its massive demand in various industries such as in biofuel production, pulp, paper, textile, food, and beverages, as well as in detergent industries. Among these, the demand of cellulase may become frequently selected in the commercial production of biofuels in the future and thus will further increase demand of cellulase in the biofuel industry. Because biofuel production is still not realized in a cost-effective, practical implementation due to its high cost (the higher cost of biofuels is due to higher production costs of enzymes), there is a need to introduce these types of approaches, which will help to lower the cost of enzyme production for developing overall economic biofuel production.

Available in PDF, EPUB and Kindle. Book excerpt: As our global population and environmental awareness increase, so does our demand for renewable, sustainable energy. The US Department of Energy has established the Energy Independence and Security Act of 2007, which mandates a total of 36 billion gallons of renewable fuel needs to be produced and blended into transportation fuel by 2022. The Act also requires that 21 billion gallons of produced renewable fuel needs to be derived from non-cornstarch material. Every year in the United States, approximately one billion dry tons of cellulosic feedstock is produced which can be used to generate biofuels. However, the process of converting cellulosic biomass into biofuel involves enzymatic hydrolysis, which contributes to a large portion of cellulosic biofuel production cost in terms of enzyme production-- it is responsible for 20-40% of cellulosic ethanol production cost. To make this alternative energy more economically friendly, reducing the cost of enzyme production needs to be investigated. This research project explores and compares the production of cellulase enzymes via traditional Trichoderma reesei, ethanol-inducible transgenic tobacco, and transient agroinfiltrated tobacco. The conceptual plant designs for each production process are assumed to annually produce 3.2 million kg of cellulase enzymes, assuming 100% active cellulase enzymes, to meet the on-site or nearby ethanol production of 61 million gallons (231 million liters) of ethanol simulated in the Humbird et al. technical report. The technoeconomic studies are modeled using Microsoft Excel and SuperPro Designer software. For each production process, early environmental and economic assessments were calculated and compared. With the early environmental assessment developed by Biwer and Heinzle, it was found that the three production processes all consist of an overall low environmental impact. Economically, fungal production would have an advantage over the field-grown, plant-based productions, due, in part, to the limited growing period (late March to late October) for growing tobacco outdoors which restricts host production to only 59% of the year. Under these assumptions, in order for plant-based productions to be as competitive as fungal production, transgenic production needs to either increase its plant density to 152 metric ton of fresh weight (FW) plant biomass/ ha or increase its expression level to 4.49 g of cellulase enzymes/ kg FW plant biomass; and transient production needs to increase its plant density to 159 metric ton of FW plant biomass/ ha and increase its expression level to 7.88 g of cellulase enzymes/ kg FW plant biomass.

Book excerpt: Cellulases are a complex group of enzymes which are secreted by a broad range of microorganisms including fungi, bacteria, and actinomycetes. In the natural environment, synergistic interactions among cellulolytic microorganisms play an important role in the hydrolysis of lignocellulosic polymer materials. In fact, it is the combined action of three major enzymes which determines the efficiency of this process. They are exoglucanases, endoglucanases, and β-glucosidase. Microorganisms produce these enzymes in a diverse nature which determines their efficiency in cellulose hydrolysis. During the cellulose degradation reaction, the enzyme targets the β-1,4-linkages in its polymeric structure. This is an essential ecological process as it recycles cellulose in the biosphere. The application of this same scenario for industrial purposes is identified as an emerging area of research. Biofuel production, textile polishing and finishing, paper and pulp industry, and lifestyle agriculture are among the key areas where cellulase enzyme shows a broader potential. The objective of this chapter is to discuss the structure, function, possible applications, as well as novel biotechnological trends of cellulase enzymes. Furthermore, possible low-cost, enzymatic pretreatment methods of lignocellulosic material in order to use it as an efficient raw material for biofuel production will be discussed.
