Fig. 1. Electron photomicrograph of an ultrathin section of a pair of cells of strain JA304T showing the vesicular nature of photosynthetic membranes extending throughout the cell. Bar, 500 nm.

Size: Cells are 2.0–2.5 µm in diameter.

Color: Saddle-brown.

The in vivo absorption spectrum of intact cells in sucrose exhibits maxima at 398, 457, 491, 524, 590, 800 and 857 nm. Bacteriochlorophyll a and lycopene are the major photosynthetic pigments. Photolithoautotrophic growth occurs under anaerobic conditions in the light. In the presence of sulfide (0.5 mM) and bicarbonate (0.1 %, w/v), organic compounds are photoassimilated. Good carbon sources are pyruvate, glucose and fructose. Growth also occurs on succinate, malate, glutamate, mannitol, sorbitol, glycerol and Casamino acids. Photoorganoheterotrophy and chemotrophy do not occur. Yeast extract is required as a growth factor. Mesophilic (30 °C). Optimum growth at pH 7.5. Growth occurs in 0.5–4.0% NaCl (w/v), with an optimum at 1.0% (w/v).
