Available in PDF, EPUB and Kindle. Book excerpt: FROM THE AUTHOR'S PREFACE This book . . . is focused on the structure and function relationships of the four major hydrolytic enzymes, cellulases, cellobiohydrolases, b-glucosidases, and xylanases as it relates to their mechanism of action. It should be of interest to biotechnologists and industrial researchers interested in manipulating these enzymes to their full potential as catalysts for various current and new applications. It begins with an overview of the nature of cellulose and heteroxylan, followed by a description of the enzymes involved in its hydrolysis, their general structure, characteristics, and classification. Chapter 3 discusses how these various enzymes are integrated and associated for the efficient solubilization of cellulose and heteroxylan. This includes a review of the literature concerning the cellulosomes and other cellulolytic complexes. The chapter on production and purification provides an overview of this subject matter. . . . These first four chapters thus set the stage for the more comprehensive discussion of the mechanism of action of each of the primary hydrolases which follows. . . . [T]he data pertaining to the catalytic mechanism of both the retaining and inverting forms of these enzymes since such studies were initiated on cellulases . . . in 1954 is reviewed in Chapter 5. The book concludes with an overview of the mode of action of the enzymes and a discussion, citing a few examples, of how the modern methods of molecular biology, enzymology, and X-ray crystallography are being used to manipulate selected enzymes for a variety of biotechnological and industrial purposes. The information in this new book will be of value to scientists and researchers working in the areas of biochemistry, botany, crop science, ecology, microbiology and mycology, in addition to those in the forestry and forest product industries.

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: "Facing the current energy crisis, people try to find alternative energy sources. Certain microbes can ferment soluble sugars to ethanol, which is a well known biofuel. Cellulosic biomass is the most abundant renewable resource. Cellulose can be broken down to soluble sugars by the cellulase enzymes produced only by some microbes. The combination of the above two processes, i.e., break-down of cellulose to sugars and conversion of sugars to ethanol, represents a major approach of solving the energy crisis through renewable biological processes. One of the bottle necks of this approach is the relatively high production cost of cellulase. In this research, the main task was to develop a separation process for cellulase using cost-effective and environment-friendly foam-based techniques. First, the foaming properties of the fermentation broth of Trichoderma reesei RUT C-30 were investigated. The experiment results showed that cellulase was not the dominant substance that caused the foaming of the fermentation broth, although the increase of cellulase concentration in the fermentation process appeared to parallel the increase in foaming tendency. Cellulase concentration was found to be only a weakly positive factor contributing to the foaming whereas the presence of cells and solid cellulose powders had negative effects on foaming. The cell wall was found to be hydrophobic according to the study conducted to observe the cells partition between hydrophobic (organic solvent: n-hexadecane) phase and hydrophilic (aqueous) phase. The finding of hydrophobic cell wall was consistent with the observation that the cells would come out with foam in the foaming study. To prevent the cell from being foamed out of the fermentor during the foaming process intended for cellulase collection, the cell immobilization in small (3mm*3mm*3mm) pieces of polyurethane (PU) foams with different porosity and pore size was also investigated. With some of the PU foam materials, the cells could be effectively immobilized and would not be foamed out during the foaming process. Nevertheless, this system did not function well in the typical stir-tank fermentor: the high shear stress present near the tip of the impeller blades appeared to strip the immobilized cells off the PU foam pellets and caused significant subsequent growth of free (not immobilized) cells in the broth. In a subsequent study of cellulase production using cellulose hydrolysate (CH) as the inducing substrate, it was observed that the addition of the hydrolysate resulted in higher enrichment ratios of cellulase concentration in the collected foamate (over the residual concentration in the spent broth). The foaming study was then expanded to include the addition of other cellulase substrates and substrate analogs, such as xylan hydrolysate (XH) and carboxylmethylcellulose (CMC). The results clearly demonstrated the addition of CH, XH and CMC would improve the enrichment and purification of cellulases by foaming. The improvements were attributed to the affinity binding between the substrates/substrate analogs and the cellulase enzymes and the increased partition of the substrate-enzyme complexes to the foam's air-liquid interfaces. To further pursue the above affinity foaming phenomenon for significantly improved collection and, potentially, purification of cellulase, a polymeric foaming agent was designed and synthesized. The polymeric surfactant has two parts, one is the hydrophobic region containing methylmethacrylate (MMA) and methacrylic acid (MAA), the other part is cellobiose, i.e., the substrate of the enzyme to bind with during foaming process. Unfortunately, the foaming ability of this synthetic surfactant was not good enough and its synthesis was complicated. As an easier first step, two glycolipid biosurfactants, sophorolipids and rhamnolipids, were investigated as the possible affinity foaming agents. Both glycolipids had a disaccharide moiety that was expected to bind selectively to the â-glucosidase in cellulase. While sophorolipids did not foam well, rhamnolipids showed great foaming ability and selectivity towards â-glucosidase. The enrichment ratio of â-glucosidase activity in the foamate reached up to 20 in the solutions prepared by cellulase powders (from Sigma). The significant benefits of such affinity foam collection and/or fractionation techniques were clearly shown."--Abstract.
