Short genome communicationsComplete genome sequence of Stenotrophomonas sp. KACC 91585, an efficient bacterium for unsaturated fatty acid hydration

- We report the complete genome sequence of Stenotrophomonas sp. KACC 91585.
- This strain is an efficient hydrating bacterium for unsaturated fatty acids.
- A set of genes concerned with the biosynthesis and metabolizing of fatty acids were identified.
- Desaturases, thioesterases, and oleate hydratase are involved in hydroxy fatty acid production.

Hydroxy fatty acids (HFAs) such as 10-hydroxystearic acid (10-HSA) and 10-hydroxy-12(Z)-octadecenoic acid (10-HOD), which are similar to ricinoleic acid, are important starting materials and intermediates for the industrial manufacture of many commodities. Stenotrophomonas sp. KACC 91585, which was isolated from lake sediment, is an efficient bacterium for unsaturated fatty acid hydration that produces 10-HSA and 10-HOD from oleic acid and linoleic acid, respectively, with high conversion rates. The complete genome of this strain is 4,541,729 bp with 63.83% GC content and devoid of plasmids. Sets of genes involved in the fatty acid biosynthesis and modification as well as modified lipids were identified in the genome, and these genes were concerned with HFA production. This genome sequence provides molecular information and elucidation for HFA production, and will be used as an efficient biocatalyst source for the biotechnological production of HFA.
