Effect of purified trichoderma reesei cellulases on formation of cotton powder ...
Heikinheimo, Lea; Miettinen-Oinonen, Arja; Paulo, Artur CavacoThe mode of action of monocomponent purified Trichoderma reesei cellobiohydrolases (CBHI and CBHII) and endoglucanases (EGI and EGII) on cotton fabrics was studied by analyzing the weight loss of the fabric, the reducing sugars, the soluble oligosaccharides and the molecular weight of the cotton powder formed. The impact of mechanical action on these factors was also evaluated. EGI and EGII released the highest...
The role of Trichoderma reesei cellulases in cotton finishing
Miettinen-Oinonen, Arja; Heikinheimo, Lea; Buchert, Johanna; Morgado, José; Almeida, Luís de; Ojapalo, P.; Paulo, Artur CavacoKnitted and woven cotton fabrics were treated with a mono component Trichoderma reesei endoglucanase (EGII) and with experimental Trichoderma cellulase mixtures containing different cellulase profiles. The cellulase action was evaluated by measuring weight loss, pilling, and bursting strength. Of the experimental mixtures, Cellulase F, being an EGII-enriched preparation, was the best mixture to obtain the highe...
