Rhodoblastus acidophila |
Rhodoblastus acidophilus, formerly known as Rhodopseudomonas acidophila, is a gram-negative purple non-sulfur bacteria. The cells are rod-shaped or ovoid, 1.0 to 1.3 μm wide and 2 to 5 μm long. They are motile by means of polar flagella, and they multiply by budding. The photopigments consist of bacteriochlorophyll a and carotenoids of the spirilloxanthin series. All strains can grow either under anaerobic conditions in the light or under microaerophilic to aerobic conditions in the dark.
