A Novel Photosynthetic Purple Bacterium Isolated from a Yellowstone Hot Spring

MICHAEL T. MADIGAN 1

1 Department of Microbiology, Southern Illinois University, Carbondale 62901

A thermophilic photosynthetic purple bacterium was isolated from the waters of a hot spring in Yellowstone National Park, Wyoming. The organism differs from all known purple bacteria in that it grows optimally at a temperature of about 50° C. The isolate contains bacteriochlorophyll a and grows autotrophically, oxidizing sulfide to elemental sulfur which is then stored as globules inside the cell. These properties indicate that the phototroph is a member of the Chromatiaceae (purple sulfur bacteria).
