Morphology

Lamprocystis roseopersicina

CELLULAR

Staining	Gram-negative
Morphology	Cells spherical to ovoid, 2-3.5 um in diameter, diplococcus-shaped before cell division.
Motility	motile by means of a single flagellum
Specialized structures	. At high sulfur concentration (4-6 mM) and light intensity (1000-2000 lx), cells may grow in long and branching cell aggregates which are embedded in slime. At more favourable growth conditions, the cell aggregates may break up into smaller clusters and more or less spherical colonies which become motile by the flagella of the composing cells; finally, individual motile cells are liberated. . Contain internal photosynthetic membrane systems of vesicular type in which the photosynthetic pigments bacteriochlorophyll a and carotenoids are located. Contain gas vacuoles in the central part of the cell. During sulfide oxidation, lobules of elemental sulfur are transiently stored in the gas vacuole-free peripheral part of the cell.
