Abstract:
This paper describes the demulsification of olive-oil/SDS emulsion (DOSE) method for selective isolation of environmental mycobacteria. A soil sample was suspended in olive oil and centrifuged. The supernatant was emulsified on plates together with SDS solution. After incubation, the colonies that had developed on the plates were surrounded by clear zones. The isolates were identified as genus Mycobacterium, and as belonging to a fast-growing group, by 16S rRNA gene sequence analysis.
