consisting of an elemental structure of a twisted sheet of three short antiparallel
strands. One side of the wedge is placoid and contains three preserved aromatic
amino acids set apart by a distance reminiscent of the length of the continuation unit
in cellulose, cellobiose (Tomme et al. 1995). This interaction is recurrently
supplemented by polar residues resulting in hydrogen bonds (Tormo et al. 1996).
The other side is ruffled and less hydrophilic in character (Table 11.1).
11.5 Production of Cellulases
The victory of any biocommodity industry relies upon the economics of production
of hydrolytic enzymes. The foremost hurdle within the exploitation of one of such
enzymes is the overpriced production in addition to other factors such as the kind and
cellulose reserve employed for production, the complexity of cellulose structure and
dropped quantities of cellulase production by cellulose degraders due to feedback
inhibition. Utilisation of fairly cheaper reserves such as lignocellulose materials in
the place of high-quality cellulose is one of the effective approaches to trim the cost
of enzyme production (Sridevi et al. 2008). Particularly, cellulose turnover by
enzymes falls rapidly with conversion resulting in shrunken yields under extended
