Abstract

Oxalic acid production by Aspergillus niger is discussed. An mutant which does not produce oxalate and for which data is presented, produces citric acid if at pH 5 with manganese present. Activity of oxaloacetate acetylhydrolase (OAH), the enzyme thought to be responsible for oxalate formation in A. niger, correlated with oxalate production and external pH seemed to be the primary factor regulating oxalic acid production by A. niger.
