Description and emendation
Original Description
expand / minimize
Gram-negative, rod-shaped cells, 1.2-4.7 μm long and 0.4-0.8 μm wide. Resting stages are absent. Motility by gliding. Colony colour is yellow to orange with a metallic tinge on TSA+20%, sea salts. Colony morphology changes with temperature, substrate and salinity. No bathochromic shift is observed on addition of 20% KOH to colonies. Slightly or moderately halop hilic. Strict aerobe. Chemoorganotroph. Catalase-positive. Metabolism is respiratory. All strains hydrolyse agar, carrageenan, starch and cellulose (endo-cellulase activity). Optimum conditions for growth are around 25°C and pH 7-8. The DNA G+C content is 32-33 mol% (determined by HPLC). Habitat: the marine environment. Member of the family Cytophagaceae.
