Microbes from the colon of Homo sapiens Some people produce methane daily, some don't. Those methane producing microbes show a blue autofluorescence when illuminated with UV-light. The exmples shown here are enrichments from methane positive persons. Phase contrast micrograph. Autofluorescence after illumination with UV light.
Cells are motile.
