Description of Citrobacter gillenii 684

Cells are Gram­stain­negative, flagellated and rod shaped. Colonies are circular, raised, entire and pink colored on MacConkey agar medium after 48 h incubation at 25℃. Cells reduce nitrate to nitrite and are positive for urease, alkaline phosphatase, esterase (C4), leucine arylamidase, valine arylamidase, trypsin, acid phosphatase, naphthol­AS­BI­phosphohydrolase (API 20NE/ZYM). Assimilate D­glucose, D­mannose, N ­acetyl­D­glucosamine, gluconate, malate, propionate, L­histidine, L­proline, D­ribose, lactate, L­alanine, L­serine (API 20NE/ID 32GN) and utilize dextrin, D­maltose, D­trehalose, D­cellobiose, D-raffinose, α ­D­lactose, D­melibiose, β ­D­glucoside, D­salicin, N ­glucosamine, β ­mannosamine, N ­galactosamine, neuraminic acid, α ­D­glucose, D­mannose, D­fructose, D­galactose, 6­methyl­glucose, D­fucose, L­fucose, L­rhamnose, inosine, D­sorbitol, D­mannitol, myo­inositol, glycerol, D­glucose, D­fructose, D­serine, glycyl­L­proline, L­alanine, L­arginine, L­aspartic acid, L­glutamic acid, L­histidine, pyroglutamic acid, L­serine, pectin, galacturonic acid, galactonic lactone, D­gluconic acid, D­glucuronic acid, glucuronamide, mucic acid, D­saccharic acid, methyl pyruvate, D­lactic acid, L­lactic acid, citric acid, α ­glutaric acid, L­malic acid, succinic acid, γ ­butyric acid, α ­butyric acid, β ­butyric acid, α ­butyric acid, propionic acid and acetic acid as sole carbon sources (Biolog GEN III).

Strain 684 (= NIBRBAC000503089) was isolated from the gut of Leopard mandarin fish ( Siniperca scherzeri) at Chungju, Chungcheongbuk Province, Korea.
