| Outline of Final Research Achievements |
Skin microbiota is concerned in several diseases and healthy condition, we thus focus on Staphylococcus aureus and S. epidermidis.
Aeromonas hydrophila converted 9cis-C18:1 to 7cis-C16:1 and 5cis-C14:1. 7cis-C16:1 showed selective anti-bacterial activity which suppressed growth of S. aureus and did not suppress growth of S. epidermidis. So, we attempted purification of 7cis-C16:1. Purification of 7cis-C16:1 was not succeeded through enzymatic process, but ODS column was effective for purification of 7cis-C16:1 (86% purity).
