Flammeovirgaceae

The Flammeovirgaceae are a family of bacteria. They belong to the phylum Bacteroidetes Cytophagales order. The type genus is Flammeovirga. The name is derived from the Latin adjective flammeus ( fire colors ) and the Latin word virga ( rod ). It refers to the color of the colonies of rod-shaped bacteria.

Appearance

The cells are straight or curved rods. You are not flagellated, but movement may be sliding in many species. The color of the colonies is pink, red or orange. Most types require seawater or at least sodium chloride (NaCl) for growth. Spores are not formed.

Growth and metabolism

All representatives of Flammeovirgaceae are chemo- organotroph. The species are aerobic, usually, they use oxygen for respiration. Persicobacter psychrovividus this is an exception, this species is a facultative anaerobe. The majority of species produce oxidase and catalase. Most species produce no acetoin, hydrogen sulfate or indole. Few species can use the fermentation of glucose, this includes eg Flammeovirga aprica.

Occurrence

The species were found in different marine habitats, such as marine sediments, in seawater or even algae. Roseivirga was, inter alia, of the green alga Ulva fenestrata, Fabibacter halotolerans isolated from the sponge Tedania ignis.

System

The two species Cytophaga aprica and Cytophaga diffluens, both first described by Reichenbach in 1989, were placed in the two new genera and Flammeovirga Persicobacter of Yasuyoshi Nakagawa 1997. The family was of Jaewoo Yoon et al. Introduced in 2011.
