Process for making polycarboxylic acids |
摘要 |
Aliphatic polycarboxylic acids are made by a process comprising the steps of: (1) fermenting a beta-oxidation blocked C. tropicalis cell wherein both copies of the chromosomal POX5 gene and the chromosomal POX4A and POX4B genes are disrupted in a culture medium comprised of a nitrogen source, an organic substrate and a cosubstrate wherein the substrate is an unsaturated aliphatic compound having at least one internal carbon-carbon double bond and at least one terminal methyl group, a terminal carboxyl group and/or a terminal functional group which is oxidizable to a carboxyl group by biooxidation; (2) reacting the product of step (1) with an oxidizing agent to produce one or more polycarboxylic acids.
