Description of Mesobacillus thioparans MBLB1969

Cells are Gram-stain-positive, flagellated, and rod-shaped cells with 1.0-1.1 μm in width by 1.9-2.2 μm in length. Colonies are pink color, circular, and raised after two days of incubation on MA at 30℃. Catalase and oxidase activities are negative. Growth occurs in the 20-45℃ (optimum, 30℃) at 0-6% NaCl (optimum, 3%) at pH 6.0-8.0 (optimum, pH 7.0). In API 20NE test, positive for the reduction of nitrates (NO 3) to nitrite (NO 2 -), esculin hydrolysis, and β -galactosidase activity; but negative for indole production, D- glucose fermentation, arginine dihydrolase, urease activity, and gelatin hydrolysis. In API 32GN test, D- mannitol, D- glucose, D- melibiose, D- sorbitol, 3-hydroxy-butyrate, L- rhamnose, D- sucrose, D- maltose, lactate, L- alanine, and glycogen are utilized; but salicin, L- fucose, L- arabinose, propionate, caprate, valerate, citrate, L- histidine, 2-ketogluconate, 4-hydroxy-benzoate, L- proline, N - acetyl-D- glucosamine, D- ribose, inositol, itaconate, suberate, malonate, acetate, 5-ketogluconate, 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 OP070049. Strain MBLB1969 (= NIBR BAC000509757 ) was isolated from a marine sediment from East Sea , Uljin-gun, Gyeongsangbuk-do, Korea (36° 42′21.8″N, 129°35′0.7″E) .
