Reclassification of Alteromonas distincta Romanenko et al. 1995 as Pseudoalteromonas distincta comb. nov.

Idiomarina baltica sp. nov., a marine bacterium with a high optimum growth temperature isolated from surface water of the central Baltic Sea

“…Strains OS145 T and OS146, isolated from the central Baltic Sea, have an unsaturated iso-branched fatty acid (C 17 : 1 iso v9c , 8?2 %) in addition to the two isobranched fatty acids observed for I. abyssalis and I. zobellii (C 15 : 0 iso and C 17 : 0 iso ) (Ivanova et al, 2000). A high proportion of iso-branching fatty acids is atypical for the Proteobacteria, and has so far only been seen in the Xanthomonas-branch Proteobacteria (Finkmann et al, 2000).…”

“…At the time of writing, the genus Idiomarina contained two species, Idiomarina abyssalis and Idiomarina zobellii, of strictly aerobic Gammaproteobacteria, which were isolated from deep-sea samples from the northwest Pacific Ocean (Ivanova et al, 2000). Comparison of the 16S rRNA gene sequences of these two species with those of submitted sequences of clones and isolates showed that related sequences were derived from deep-sea sediments, with sequences from a hydrothermal mound of the Mid-Atlantic Ridge showing the highest similarity, while those of Pacific deep-sea organisms were more distantly related.…”

Pseudoalteromonas sagamiensis sp. nov., a marine bacterium that produces protease inhibitors

“…Table 1 shows a comparison of the characteristics of strain B-10-31 T with those of related genera, namely, Idiomarina, Colwellia, Thalassomonas and Glaciecola, which accommodate Gram-negative, rod-shaped bacteria common in marine habitats. Species of aerobic marine bacteria that belong to the genus Idiomarina, namely, I. zobellii and I. abyssalis, have been isolated from sea water at a depth of 4000-5000 m (Ivanova et al, 2000). Strain B-10-31 T showed the second highest (only 0?1 % lower than P. bacteriolytica) 16S rDNA sequence similarity (90?3 %) to I. abyssalis.…”

Pseudoalteromonas lipolytica sp. nov., isolated from the Yangtze River estuary

“…They are motile by a single polar flagellum and have a chemoheterotrophic metabolism (Bowman & McMeekin, 2005). At the time of writing, the genus Pseudoalteromonas comprises 34 species with validly published names (Gauthier et al, 1995;Ivanova et al, 1996Ivanova et al, , 1998Ivanova et al, , 2000Ivanova et al, , 2001 Ivanova et al, , 2002a Ivanova et al, , b, c, d, 2004Bozal et al, 1997; Euzéby, 1997;Bowman, 1998; Holmström et al, 1998; Sawabe et al, 2000;Venkateswaran & Dohmoto, 2000;Egan et al, 2001;Isnansetyo & Kamei, 2003; Romanenko et al, 2003a, b;Lau et al, 2005;Park et al, 2005;Nam et al, 2007;Al Khudary et al, 2008). Some strains produce yellow, red, violet or melanin-like pigments and have the ability to form antibiotic substances (Bowman, 2007).…”
