When tested, Flavobacterium marinum was positive for catalase and oxidase activities, negative for a variety of other metabolic tests, and was found to be incapable of reducing nitrate to nitrite(1). Aéro-anaérobie. The 3Micrococcus isolates (37R, 45R and 49R) were red-pigmented and h a d ∼ 75 mol% G + C in their DNA; they were identified asMicrococcus roseus. Flavobacterium is a genus of bacteria into which F. marinum is classified. Oxidase was determined with cytochrome oxidase test paper (Nissui Seiyaku, Tokyo, Japan).
