Eighteen strains of xylariaceous fungi have been screened for higher activities of cellulolytic enzymes, Trichoderma reesei QM 9414 was also examined for comparison. Strains of Xylaria anisopleura and X. regalis had higher endocellulase (CMCase) and exocellulase (Avicelase) activities after 2 weeks' incubation. Hypoxylon stygium produced the highest activity of β-glucosidase 3 days after inoculation. The optimum pH for these cellulolytic enzymes was approx. 5.0 and the optimum temperatures ranged from 37 to 50°C. A mixed culture process using T. reesei QM 9414 and H. stygium was developed to obtain enhanced synthesis of cellulase. β-Glucosidase activities in the mixed culture increased within 48h when H. stygium was introduced after 24h.
