  Fermentative production of oxalic acid by Aspergillus niger NCIM 548 strain depended on the initial medium pH and better yield was obtained at pH 4-7. Yield of oxalic acid augmented (2.5 to 3-fold) if pH of the broth was maintained at 6-7 by occasional addition of alkali. The strain produced more oxalic acid from glucose with ammonium salts, especially diammonium hydrogen phosphate, as the N-source in comparison to other ammonium salts, NaNO3 and urea. With lactose as the C-source, yield of oxalic acid was maximum with ammonium dihydrogen phosphate closely followed by diammonium hydrogen phosphate; the yield was much better with urea than with ammonium nitrate or ammonium sulphate.
