Fig. 5From: Xylose induces cellulase production in Thermoascus aurantiacus 2 L bioreactor cultivation of T. aurantiacus at different pH values. T. aurantiacus protein production was performed with no pH control (a), at pH 4 (b), at pH 5 (c) and pH 6 (d) using xylose as the substrate in fed-batch cultivations. The pH was maintained by automated addition of HCl to culturesBack to article page
