The effect of methanol on the ability of several strains of Aspergillus to produce citric acid from galactose has been investigated. In the absence of methanol, very little production (less than 1 g/l) was observed. In the presence of methanol (final concentration 1% v/v), however, citric acid production and yeilds were increased considerably. Strong relationships were observed between citric acid production and the activities of the enzymes 2-oxoglutarate dehydrogenase and pyruvate carboxylase… CONTINUE READING
