Enhanced production of cellobiohydrolases in Trichoderma reeseiand evaluation of the new preparations in biofinishing of cottonrystalline cellulose (reviewed by Teeri, 1997). Theendoglucanases hydrolyse the cellulose chains internally,providing new chain ends for cellobiohydrolases.The cellobiohydrolases hydrolyse the cellulose progressivelyfrom the ends to create mainly cellobiose.CBHII splits cellobiose from the non-reducing andCBHI from the reducing ends of cellulose chains. Thecomplementary activities of endoglucanases and cellobiohydrolaseslead to synergy, i.e. enhancement ofactivity over the added activities of the individual enzymes.Cellulases of T. reesei are widely used in several industrialapplications, for example in the food and feed(Galante et al., 1998a) and pulp and paper industries(Buchert et al., 1998) as well as in the textile industryin biostoning and biofinishing applications (Galante etal., 1998b). In biofinishing, individual loose fibre endsthat protrude from the textile surface are removed fromcellulose-containing textile materials, such as cottonfabrics. The key benefits are permanent improvementof depilling, cleared surface structure by reduced fuzz,improved textile handling (softness), brighter coloursof the textile and improved dimensional stability andmoisture absorbability. Endoglucanases are known tobe important in obtaining biofinishing effects of cot
