Abstract
A process for the preparation of an unsaturated dicarboxylic acid which comprises cultivating under aerobic conditions a yeast belonging to Candida tropicalis which is capable of producing an unsaturated dicarboxylic acid from an unsaturated fatty acid or its ester, such as Candida tropicalis 104-04 strain, in a medium containing an unsaturated fatty acid having 14 to 22 carbon atoms or its ester, to produce an unsaturated dicarboxylic acid having 14 to 22 carbon atoms; or effecting oxidation of said fatty acid or its ester in the presence of microorganisms of said yeast produced in advance by cultivation in an assimilable carbon source to produce an unsaturated dicarboxylic acid having 14 to 22 carbon atoms; and then recovering the thus-produced unsaturated dicarboxylic acid.
