Abstract
AIM
To find cis-11-eicosenoic acid (20:1ω9, EA)-producing micro-organisms.
METHODS AND RESULTS
We found EA-producing fungi by screening about 300 fungal strains and identified a major fatty acid accumulated in the Mortierella fungi as EA by means of GC-MS analysis. In particular, Mortierella chlamydospora CBS 529.75 produced a high amount of EA (36.3 mg g(-1) of dried cells) on cultivation at 28°C for 4 days and then at 12°C for 3 days. In the result of lipid analysis, most of the EA was a component of triacylglycerols, not phospholipids.
CONCLUSION
We found that M. chlamydospora CBS 529.75 was the best producer for the microbial production of EA.
SIGNIFICANCE AND IMPACT OF THE STUDY
EA is beneficial as a raw material for medical supplies and a moisturizing component of cosmetic creams. This is the first report of microbial production of EA.
