Description and emendation
Original Description
expand / minimize
Gram-negative. Cellular morphology ranges from rod-like cells to coiled filaments and filaments of indeterminate length. Coccoid cells are present in older cultures. Ring-shaped cells and gas vesicles are not formed. Resting stages are absent. Either non-motile or motile via slow gliding motility. Orange carotenoid-like pigments are formed. Flexirubin pigments are absent. Strictly aerobic chemoheterotroph. Psychrophilic or psychrotrophic. Slightly or moderately halophilic. Major cellular fatty acids are α-C15:0, α-C15:10 ω10c, i-C16:0, 3-OH i-C16:0 and 3-OH α-C17:0. Major respiratory quinone is menaquinone-6 (determined for Psychroflexus gondwanense only). The DNA G+C content is 32-36 mol% (Tm).
