| Abstract: | Adsorption isotherms for SF cellulase from Trichoderma pssudokoningii on cotton, flax and viscose yarns were investigated to provide information about cellulase-cellulose binding on different types of cellulosic fibres. The half-saturation constants and maximum adsorption constants suggest that SF cellulase has greater affinity for viscose than for cotton and greater affinity for cotton than for flax. It is suggested that this is related to the different crystallinities and microporous structures of these fibre types. The fraction of adsorbable protein in the total cellulase was found to be the same for each of the three cellulase substrates. |
