Description of Rhodobacter blasticus SSH 19

Strain SSH19 (= CYQTBAC000000083) was isolated from freshwater sediment in Susan, Jeju, Korea. SSH19 cells are Gram-stain-negative, non-flagellated, and rod-shaped (2.0 × 3.0 μm). The colonies are circular, convex, and red colored after 2 days of incubation on AR2A at 30°C. Cells are positive for oxidase and catalase activity, and glucose acidification, and negative for reduction of nitrates (NO 3 -) to nitrite (NO 2 -), reduction of nitrates (NO 3 -) to nitrogen (N 2), indole production. Also, cells show positive activity for β-glucosidase (esculin hydrolysis), esterase (C4), esterase lipase (C8), leucine arylamidase, valine arylamidase, cystine arylamidase, acid phosphatase, Naphthol-AS-BI-phosphohydrolase, α-glucosidase, and β-glucosidase, but negative activity for arginine dihydrolase, urease, protease (gelatin hydrolysis), β-galactosidase (PNPG), alkaline phosphatase, lipase (C14), trypsin, α-chymotrypsin, α-galactosidase, β-glucuronidase, N -acetyl-β-glucosaminidase, α-mannosidase, and α-fucosidase. Moreover, cells are positive for utilization of D-glucose, L-arabinose, D-mannose, D-mannitol, D-maltose, gluconate, adipate, malate, citrate, phenyl-acetate, salicin, L-fucose, D-sorbitol, propionate, valerate, L-histidine, 2-ketogluconate, 3-hydroxy-butyr- ate, 4-hydroxy-benzoate, L-proline, L-rhamnose, inositol, itaconate, lactate, L-alanine, 5-ketogluconate, glycogen, 3-hydroxy-benzoate, and L-serine, and negative for utilization of N -acetyl-D-glucosamine, caprate, D-melibiose, D-ribose, D-sucrose, suberate, malonate, and acetate as energy and carbon source.
