Summary

Batch cultivation of Aspergillus wentii, Wehmer, Pt 2804 was carried out on Mandels and Reese (1957) medium containing 3% cellulose and 0.3% peptone at 30°C in 14 and 30 liter Bioreactors. Use of a 48 hours old inoculum (10% v/v), 0.5 vvm aeration at 400–800 rpm and maintenance of dissolved oxygen and pH above 50% saturation level and between 5.2 to 4.0 respectively, produced 10.58 g cells/lit and 61.9 IU/1/hr cellobiase productivity.
