Morphology | Prosthecochloris |
CELLULAR |
Staining | Gram-negative |
Morphology | Spherical to ovoid bacteria forming nonbranching prosthecae and multiplying by binary fission in various directions. When separation is incomplete, cells form groups and branched chains, the configuration of which depends on the direction of fissions. |
Motility | Nonmotile |
Specialized structures | .. Cell suspensions appear green or chocolate-brown. Cells contain bacteriochlorophyll c, d or e, as the major bacteriochloro-phyll component, and carotenoids. The photosynthetic apparatus includes antenna structures, chlorosomes, i.e. elongated-ovoid vesicles underlying and attached to the cytoplasmic membrane. Cells do not contain gas vacuoles. |

Tropism | Capable of photosynthesis in the presence of hydrogen sulfide, during which they produce and deposit, as an intermediate oxidation product, elemental sulfur in the form of globules outside the cells in the medium. |
