Abstract

L-malic acid is produced by cultivating under aerobic conditions a 1-malic acid-producing strain of Aspergillus parasiticus spheare, Aspergillus flavus Link or Aspergillus oryzae (ahlburg) Cohn in a culture medium containing assimilable sources of carbohydrate, nitrogen and inorganic salts, adding calcium carbonate and/or magnesium carbonate whereby the pH of the medium is maintained within the rante of 5.0 to 7.5, until a substantial amount of 1-malic acid salt is produced, recovering said salt, and converting it to 1-malic acid by any known method. An organic acid such as pyruvic or fumaric acid, or a salt thereof, may be added as may at least one of the salts FeSO4, MnCl2, Al2(SO4)3 and K2Cr2O7. Liquid or solid media may be used. Temperatures of 20 DEG C.-35 DEG C. are suitable.
