7,10-Dihydroxy-8(E)-octadecenoic acid produced by Pseudomonas 42A2: evaluation of different cultural parameters of the fermentation.

A fermentation process for the microbial production of a new lipid surface-active compound, 7,10-dihydroxy-8 (E)-octadecenoic acid (OCD), has been established using a vegetable oil as carbon source in a coordinated carbon/nitrogen feed strategy. The surfactant was produced during the logarithmic growth phase. Aeration was the most critical parameter for product formation. Up to 7 g product/l was produced.
