Summary

Xylanase is synthesized byTrichoderma reesei when grown in the presence of xylan, cellulose or phosphocellulose. Xylan is the best inducer of xylanase. Other cellulolytic enzymes such as endoglucanase and FPase are synthesized in small quantities, but the level of β-glucosidase is very high. Mutants with altered levels of cellulolytic enzymes showed an unaltered level of xylanase, suggesting its independent control in this organism.

Résumé

Une xylanase est synthétisée parTrichoderma reesei lorsque cet organisme est cultivé en présence de xylane, de cellulose ou de phospho-cellulose. Le xylane est le meilleur inducteur. D'autres enzymes cellulolytiques, notamment une endo-glucanase et une FP-ase, sont synthétisées en faibles quantités, mais le niveau en β-glucosidase est trés élevé. Des mutants ayant des niveaux d'enzymes cellulolytiques modifiés présentent un niveau de xylanase inchangé, ce qui suggère que cette enzyme est contrôlée de façon indépendante.

Resumen

Trichoderma reesei sintetiza xilanasa cuando se hace crecer en presencia de xilano, celulosa o fosfocelulosa. El xilano es el mejor inductor de xilanosa. Tambien se producen otros enzimas celulolíticos en pequeñas cantidades como endoglucanasa y FPasa aunque la producción de β-glucosidasa puede alcanzar niveles elevados. Mutantes con niveles de enzimas celulolíticos alterados no mostraron ninguna modificación en los niveles de xilanasa sugiriéndose pues un control independiente de dicho enzima en este organismo.
