Zhangella mobilis gen. nov., sp. nov., a new member of the family Hyphomicrobiaceae isolated from coastal seawater.

A Gram-negative, pale-yellow, non-spore-forming bacterium, motile with single polar flagella, strain E6T, was isolated from coastal seawater collected from Tianjin, China, and its taxonomic position was investigated using a polyphasic approach. Strain E6T requires NaCl for growth and grows optimally at pH 8.2 and 36 degrees C and in the presence of 2.

Lishizhenia tianjinensis sp. nov., isolated from coastal seawater.

A Gram-negative, non-carbohydrate-utilizing, non-flagellated, motile, flexible, long rod-shaped, orange-pigmented bacterium, strain H6(T), was isolated from coastal seawater of Tianjin City, China, and its taxonomic position was investigated by using a polyphasic approach. Strain H6(T) grew optimally at 30 degrees C, in the presence of 2.0 % (w/v) NaCl and at pH 7.

Glaciecola lipolytica sp. nov., isolated from seawater near Tianjin city, China.

A Gram-negative, non-spore-forming, rod-shaped bacterium, designated strain E3T, which was motile with a polar flagellum, was isolated from coastal surface seawater near Tianjin city, China. The taxonomy of strain E3T was studied by phenotypic, chemotaxonomic and phylogenetic methods. Strain E3T forms non-pigmented colonies with a butyrous-mucoid consistency on marine 2216 agar.
