Description of Arenibacter catalasegens MBLB2431

Cells are Gram-stain-negative, non-flagellated, and short rod-shaped cells with 0.7-0.9 μm in width by 1.5-1.9 μm in length. Colonies are orange color, circular, and raised after two days of incubation on MA at 30℃. Catalase and oxidase activities are negative. Growth occurs in the 10- 40℃ (optimum, 30℃) at 0-6% NaCl (optimum, 3%) at pH 5.0-9.0 (optimum, pH 7.0). In API 20NE test, positive for esculin hydrolysis and β -galactosidase activity; but negative for reduction of nitrates (NO 3) to nitrite (NO 2 -), indole production, D- glucose fermentation, arginine dihydrolase, urease activity, and gelatin hydrolysis. In API 32GN test, D- mannitol, D- glucose, salicin, D- melibiose, D- sorbitol, L- arabinose, 2-ketogluconate, 3-hydroxy-butyrate, 4-hydroxy-benzoate, L- rhamnose, N - acetyl-D- glucosamine, D- ribose, inositol, D- sucrose, D- maltose, acetate, lactate, 5-ketogluconate, glycogen, and 3-hydroxy-benzoate are utilized; but L- fucose, propionate, caprate, valerate, citrate, L- histidine, L- proline, itaconate, suberate, malonate, L- alanine, and L- serine are not utilized as a sole energy source. The NCBI accession number for the 16S rRNA gene sequence is OP080644. Strain MBLB2431 (= NIBR BAC000509763 ) was isolated from a marine sediment from East Sea , Uljin-gun, Gyeongsangbuk-do, Korea (36° 42′21.8″N, 129°35′0.7″E) .
