✦ Synopsis

Batch cultivation

of Aspergillus wentii, Wehmer, Pt 2804 was carried out on Mandels and Reese (19571 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 wm aeration at 400-800 rpm and maintenance of dissolved oxygen and pH above 50% saturation level and between 5.2 to 4.0 respective:Ly, produced 10.58 g cells/lit and 61.9 IU/l/hr cellobiase productivity.
