A Novel Isolate (S15) of Streptomyces griseobrunneus Produces 1-Dodecanol.

One-dodecanol was identified to be the predominant secondary metabolite of a novel isolate (S15) of Streptomyces griseobrunneus. For its demonstration, secondary metabolite extracts were electrophoresed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). A yellowish unique band was then cut out from the gel and its metabolite content was eluted in n-butanol. GC-MS analysis indicated that more than 93% of the of the elution material were 1-dodecanol. The compound was further characterized by FTIR and 13C NMR analyses. Dendrogram built on the basis of 16S rRNA gene sequence indicated that the isolate S15 was a member of Streptomyces griseobrunneus.
