Lam'pro.bac'ter. Gr. adj. lampros bright, brilliant; M.L. masc. n. bacter rod; M.L. masc. n. Lamprobacter brilliant rod.

Cells are rod shaped or ovoid, 2.0-2.5 X 4-5 |im, multiply by binary fission, do not form aggregates. Gas vesicles formed in cell periphery or in the entire cytoplasm. Motile by flagella during certain stages of development. Motile cells normally devoid of gas vesicles. Gram negative, belong to the Gammaproteobacteria, and contain internal photosynthetic membranes of vesicular type with bacteriochlorophyll a and carotenoids as photosynthetic pigments.

Photolithoautotrophic growth under anoxic conditions in the light with reduced sulfur compounds as electron donors. During oxidation of sulfide or thiosulfate, S0 transiently stored inside the cells in the form of highly refractile globules. In the presence of sulfide and bicarbonate, simple organic substrates are pho-toassimilated. Chemotrophic growth under microoxic conditions in the dark.

Type species: Lamprobacter modestohalophilus Gorlenko,
