Flammeovirga is a genus of bacteria and belongs to the family Flammeovirgaceae .

Appearance

The cells are straight or curved rods. The size is between 0.4 µm and 0.9 µm in width and between 1.7 µm and 96 µm or more in length. They are not flagellated, movement is gradual. The color of the colonies is orange to reddish orange. Most species require seawater or NaCl . Spores are not formed.

The dominant menaquinone is MK-7. The GC content in the DNA of the species is between 31–36 mol percent.

Growth and metabolism

All types of Flammeovirga are chemo-organotrophic . The metabolism is respiration , the species are aerobic , the terminal electron acceptor in respiration is oxygen .

Occurrence

The species have been found in various marine habitats, e.g. B. in lake water, in coastal sand or on marine algae .

Systematics

The species Cytophaga aprica , first described by Hans Reichenbach in 1989, in 1997 by Yasuyoshi Nakagawa et al. set as type species in the new genus Flammeovirga .

Some species of the genus:

etymology

The generic name Flammeovirga is derived from the Latin adjective flammeus (fire-colored) and the Latin word virga , (chopsticks). The name refers to the orange to reddish-orange color of the colonies of these rod-shaped bacteria.
