Bacteroidetes / Flavobacteriia / Flavobacteriales / Flavobacteriaceae / Muricauda

Gram‐negative, aerobic or facultatively anaerobic, rods. Cells of older cultures are characterized by long and relatively thick (20-30 nm) appendages of variable length that end in a spherical vesicle (100-400 nm wide) that may be covered by fibrillar material. Reproduce by normal cell division. Cells occur singly or in aggregates linked together by appendage structure. Nonmotile. Do not form spores. Form yellow to orange carotenoid pigments and do not form flexirubin pigments. Chemoheterotrophic. Oxidase and catalase positive. Capable of growth on a range of carbohydrates and some amino acids and organic acids. Mainly mesophilic and neutrophilic. Halophilic requiring either Na⁺ ions or sea salts for growth. The major fatty acids are C_15:0, iso‐C_15:0, iso-C_15:1, iso‐C_15:0 3-OH, iso‐C_16:0 3-OH, iso‐C_17:0 3-OH, and summed feature 3 (C_16:1 ω7c and/or iso-C_15:0 2‐OH). The major quinone is MK‐6. Members of the phylum Bacteroidetes, class Flavobacteriia, order Flavobacteriales, family Flavobacteriaceae. Known habitats are marine and saline environments including seawater and sediment.

DNA G + C content (mol%): 39.9-50.7 (HPLC or genome).

Type species: Muricauda ruestringensis Bruns, Rohde and Berthe‐Corti 2001, 2005^VP.
