Summary

The effect of varying fermentation pH and temperature on extracellular xylanase production by the thermophilic fungus,Thielavia terrestris (ATCC 26917), was studied using a stirred tank bioreactor. Maximum xylanase activity (18.8 I.U/mL) was obtained when the temperature was controlled at 48°C and the initial pH set at 4.0. Under these conditions, the volumetric productivity of xylanase was 1044 l. U./L. h. which is superior to that achieved by many mesophilic xylanolytic micro-organisms.
