Description of Paenibacillus contaminans MBLB1992

Cells are Gram-stain-positive, flagellated, and rod-shaped cells with 0.7-0.9 μm in width by 2.1-2.8 μm in length. Colonies are colorless, semi-transparent, circular, and convex after two days of incubation on R2 A at 30℃. Catalase activity is negative, but oxidase activity is positive. Growth occurs in the 10-40℃ (optimum, 30℃) at 0-2% NaCl (optimum, 1%) at pH 6.0-8.0 (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 -), reduction of nitrates (NO 3) to nitrogen (N 2), indole production, D- glucose fermentation, arginine dihydrolase, urease activity, and gelatin hydrolysis. In API 32GN test, D- glucose, salicin, D- melibiose, N - acetyl-D- glucosamine, D- sucrose, and D- maltose are utilized; but D- mannitol, L- fucose, D- sorbitol, L- arabinose, propionate, caprate, valerate, citrate, L- histidine, 2-ketogluconate, 3-hydroxy-butyrate, 4-hydroxy-benzoate, L- proline, L- rhamnose, D- ribose, inositol, itaconate, suberate, malonate, acetate, lactate, L- alanine, 5-ketogluconate, glycogen, 3-hydroxy-benzoate, and L- serine are not utilized as a sole energy source. The NCBI accession number for the 16S rRNA gene sequence is OP077213. Strain MBLB1992 (= NIBRBAC000509758) was isolated from marine sediment from the East Sea , Uljin-gun, Gyeongsangbuk-do, Korea (36°42′21.8″N, 129°35′0.7″E) .
