Subset |
Morphology | Thiodicyton |
CELLULAR |
Staining | Gram-negative |
Morphology | Cells rod-shaped with rounded ends, sometimes appearing spindle-shaped.,. May form aggregates in which the cells are arranged end to end in an irregular netlike structure, the shape of which is not constant. May also form more compact clumps or break up into individual cells.. |
Motility | non-motile under all conditions |
Specialized structures | Contain internal
photosynthetic membrane systems of vesicular type in
which the photosynthetic pigments bacteriochlorophyll a
and carotenoids are located. Contain large, irregular
shaped gas vacuoles in the central part of the cell
During sulfide oxidation, globules of elemental sulfur are transiently stored in the gas vacuole- free peripheral part of the cell |
