Selecting cellulases for bio-polishing based on enzyme selectivity and process conditions

Three cellulase compositions were investigated for the bio-polishing of a c ellulosic fabric. An add cellulase complex, an endo-enriched cellulase, and a mono-component endoglucanase were compared based on their selectivity an d sensitivity to process conditions. All cellulases have similar applicatio n pH and temperature ranges; however, their sensitivity to liquor ratio and to mechanical agitation differ significantly. The significance of their di fference is addressed. For optimal bio-polishing performance, an enzyme pro duct should be selected based on cellulase selectivity, existing equipment, and fiber type.
