Oceanisphaera donghaensis sp. nov., a halophilic bacterium from the East Sea, Korea.

Oceanisphaera ostreae sp. nov., isolated from seawater of an oyster farm, and emended description of the genus Oceanisphaera Romanenko et al. 2003.

A Gram-stain-negative, motile, non-spore-forming and short rod- or rod-shaped bacterial strain, T-w6(T), was isolated from seawater of an oyster farm in the South Sea, Korea. Strain T-w6(T) grew optimally at 25 °C and in the presence of 2% (w/v) NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain T-w6(T) joined the cluster comprising Oceanisphaera species with a bo...

Oceanisphaera profunda sp. nov., a marine bacterium isolated from deep-sea sediment, and emended description of the genus Oceanisphaera.

A Gram-stain-negative, aerobic, oxidase- and catalase-positive, flagellated, rod-shaped bacterial strain, designated SM1222(T), was isolated from the deep-sea sediment of the South China Sea. The strain grew at 4-35 °C and with 0.5-8 % NaCl (w/v). Phylogenetic analysis based on the 16S rRNA gene sequences revealed that strain SM1222(T) was affiliated with the genus Oceanisphaera in the class Ga...

Sulfitobacter litoralis sp. nov., a marine bacterium isolated from the East Sea, Korea.

A Gram-negative, aerobic, halophilic bacterium, designated strain Iso 3(T), was isolated from the East Sea in Korea. Strain Iso 3(T) was motile by means of polar flagella, occasionally formed rosette-like aggregates and contained 18 : 1omega7c as the dominant cellular fatty acid. Strain Iso 3(T) grew at NaCl concentrations of 1-10 % and temperatures of 4-30 degrees C. The optimal growth tempera...

Marinobacter nitratireducens sp. nov., a halophilic and lipolytic bacterium of the family Alteromonadaceae isolated from coastal surface sea water

Clostridium ganghwense sp. nov., isolated from tidal flat sediment.

A Gram-negative, strictly anaerobic, halophilic, motile, sporulating and rod-shaped bacterium, designated strain HY-42-06T, was isolated from tidal flat sediment from Ganghwa Island in South Korea. The isolate produced glycerol, ethanol and CO2 as fermentation end-products from glucose. Strain HY-42-06T grew optimally at 35 degrees C, pH 7.5 and 3 % (w/v) artificial sea salts. No growth was obs...
