Phylum Actinobacteria, Class Actinobacteria, Subclass Actibacteridae, Order Actynomycetales, Suborder Corynebacterinae, Family
Corynebacteriaceae, Genus Corynebacterium, Corynebacterium marinum Du, Jordan, Rooney, Chen and Austin 2010.
Description is based on a single isolate.
Gram-positive, short, diphtheroid rods; some cells are arranged in a V formation.
Colonies on MA (marine agar 2216E, Difco) medium are erose, convex, yellow,
creamy and 0.5-1.5 mm in diameter after 48 h at 28 ºC. Lyses horse blood cells.
Grows at 4-37 ºC; 30-32 ºC optimum. Grows in 0-8% NaCl (optimum 1%).
Isolated from coastal sediment close to a coal-fired power station in Qingdao, China. Resistant to cotrimoxazole, tetracycline, nalidixic
acid, nitrofurantoin, sulphamethizole. Sensitive to ampicillin, chloramphenicol, gentamycin, kanamycin, carbenicillin and streptomycin.
