Summary

Enzyme preparations fromTrichoderma reesei RUT-C30, in addition to cellulase, contained various glucanase and glucosidase, acetylxylan esterase, glucuronidase and xylanase activities. These preparations were able to hydrolyse endosperm cell walls of corn and wheat and commercially-available xylans and plant gums having stright chains, but lacked the ability to hydrolyse branched or substituted hemicelluloses.

Formation d'enzymes requises pour l'hydrolyse des polysaccharides de la paroi de plantes chez Trichoderma reesei

Résumé

Les préparations enzymatiques deTrichoderma reesei RUT-C30, contiennent, outre la cellulase, diverses glucanases et glucosidases, acétyl-xylane esterases, glucuronidases et xylanases. Ces préparations demeurent stables pour l'hydrolyse de parois cellulaires de l'endosperme de maïs et de froment ainsi que des xylanes et gommes de plantes à chaînes linéaires, disponibles dans le commerce, mais ne présentent pas le pouvoir d'hydrolyser les hémicelluloses branchées ou substituées.
