Abstract

The xylanolytic enzymes produced by Trichoderma reesei QM 9414, Aspergillus awamori VTT-D-75028, Fusarium oxysporum VTT-D-80134, Bacillus subtilis ATCC 12711 and Streptomyces olivochromogenes ATCC 21713 differed with respect to β-xylosidase activity and side-group cleaving activities.
The highest xylanase activity was produced by T. reesei. All the fungi produced β-xylosidase, whereas in the bacterial culture filtrates β-xylosidase activity was negligible. T. reesei culture filtrate contained all the side-group cleaving activities assayed (acetyl esterase, α-glucuronidase and α-arabinosidase) and those of F. oxysporum and S. olivochromogenes contained esterase.
All the side-group cleaving activities were low in the culture filtrates of A. awamori and B. subtilis.

The differences between the xylanolytic systems were reflected in the hydrolysis of steamed birchwood hemicellulose. The xylose yields obtained ranged from 0 (with B. subtilis) to 90% (with T. reesei) of the theoretical maximum. The best enzyme for complete hemicellulose hydrolysis was therefore that of T. reesei.
However, in some applications in which complete hydrolysis is not needed or in which hydrolysis of cellulose is to be avoided, one of the other xylanases may be more suitable than that of T. reesei.
