| Halopseudomonas oceani |
Description is based on API 20 NE, API ZYM and Biolog GN2 results.
Positive results for acid and alkaline phosphatase, catalase, esterase (C4), esterase lipase (C8), lipase (C14), leucine arylamidase,
naphthol-AS-BI-phosphohydrolase, oxidase, Tween 20 and 40 hydrolysis.

Species description is based on a single isolate.
Gram-stain-negative rods, 0.4-0.6 x 2.1-2.6 μm. Motile by one polar flagellum.
Colonies are circular, smooth, non-pigmented, whitish and transparent. Fluorescent
pigments are not produced in King B medium. Strictly aerobic. Growth occurs at 4-41
ºC, pH 6.0-10.0 and with 0-10% NaCl.
