Abstract

PURPOSE: To improve the yield of an organic acid having surface activity, by the aerobic fermentation of microbials in a medium containing vitamin P as well as a saccharide as a carbon source and an acidic nitrogen source, at a low pH.
CONSTITUTION: An organic acid having a number of active groups such as alcohol group, carboxyl group, long-chain alkyl group, etc. in the molecule, is prepraed by the aerobic culturing of microbials such as bacteria, molds, yeasts, etc., e.g. Penicillium spiculisporium Lehmann No.1, in a medium containing mono- or poly- saccharide as a carbon source, ammonium chloride, ammonium sulfate, ammonium acetate, etc., as an acidic nitrogen source or corn steep liquor, and 0.1-10% of vitamin P, at pH≤4. The addition of vitamin P improves the yield of the organic acid to 2-3 times that of the conventional process.
