Abstract

Lam' pro.cys' tis. Gr. adj. lampros bright, brilliant; Gr. n. cystis the bladder, a bag; M.L. fem. n. Lamprocystis brilliant bag.

Proteobacteria / Gammaproteobacteria / Chromatiales / Chromatiaceae / Lamprocystis

Cells spherical to ovoid, 1.9–3.8 µm in diameter, diplococcusshaped before cell division and may occur in irregular aggregates, multiply by binary fission, nonmotile or motile by means of a single flagellum, form gas vesicles in central part. Gram negative and belong to the Gammaproteobacteria. At high sulfide concentration (4–6 mM) and light intensity (1000–2000 lux), cells may grow as long, branching cell aggregates embedded in slime. Under favorable growth conditions, cell aggregates may break up into smaller clusters and spheroidal microcolonies, which become motile by flagella; finally, individual motile cells are liberated. Internal photosynthetic membranes are of vesicular type and contain the photosynthetic pigments bacteriochlorophyll a and carotenoids.

The mol% G + C of the DNA is: 63.4–64.1.

Type species: Lamprocystis roseopersicina (Kützing 1849) Schroeter 1886, 151 (Protococcus roseopersicinus Kützing 1849,196.)
