Characterization of several Psychrobacter strains isolated from Antarctic environments and description of Psychrobacter luti sp. nov. and Psychrobacter fozii sp. nov.

Psychrobacter aquimaris sp. nov. and Psychrobacter namhaensis sp. nov., isolated from sea water of the South Sea in Korea

“…These fatty acid profiles were similar to those determined previously for other Psychrobacter species, although there were differences in the proportions of some fatty acids, perhaps because of differences in cultivation conditions, e.g. cultivation media (Maruyama et al, 2000;Romanenko et al, 2002Romanenko et al, , 2004Bozal et al, 2003;Yumoto et al, 2003;Yoon et al, 2005). The DNA G+C contents of strains SW-210 T and SW-242 T were 43?2 and 45?3 mol%, respectively.…”

“…1). The thermal tolerance and chemotaxonomic data (the predominant respiratory lipoquinone, the cellular fatty acid profile and the DNA G+C content) for strains SW-210 T and SW-242 T are similar to those for Psychrobacter species (Bøvre, 1984;Kodjo et al, 1995Kodjo et al, , 1997Bowman et al, 1997;Maruyama et al, 2000;Yoon et al, 2003;Bozal et al, 2003;Yumoto et al, 2003). Strains SW-210 T and SW-242 T are similar to each other in terms of most phenotypic characteristics (Table 1).…”

“…The genus Psychrobacter was proposed by Juni & Heym (1986), and, at the time of writing, the genus comprises at least 18 species with validly published names: Psychrobacter immobilis (Juni & Heym, 1986), Psychrobacter frigidicola, Psychrobacter urativorans and Psychrobacter phenylpyruvicus (Bowman et al, 1996), Psychrobacter glacincola (Bowman et al, 1997), Psychrobacter pacificensis (Maruyama et al, 2000), Psychrobacter proteolyticus (Denner et al, 2001), Psychrobacter submarinus and Psychrobacter marincola (Romanenko et al, 2002), Psychrobacter faecalis (Kämpfer et al, 2002), Psychrobacter pulmonis (Vela et al, 2003), Psychrobacter jeotgali (Yoon et al, 2003), Psychrobacter luti and Psychrobacter fozii (Bozal et al, 2003), Psychrobacter okhotskensis (Yumoto et al, 2003), Psychrobacter maritimus and Psychrobacter arenosus (Romanenko et al, 2004) and Psychrobacter alimentarius (Yoon et al, 2005). In this study, we report on the detailed taxonomic characterization of two Psychrobacter-like bacterial strains, SW-210 T and SW-242 T , which were isolated from sea water of the South Sea in Korea.…”

Psychrobacter piscatorii sp. nov., a psychrotolerant bacterium exhibiting high catalase activity isolated from an oxidative environment

“…Differential phenotypic characteristics of strain T-3-2 T and related Psychrobacter species Strains: 1, P. piscatorii sp. nov. T-3-2 T ; 2, P. nivimaris 88/2-7 T (unless indicated, data from Heuchert et al, 2004); 3, P. proteolyticus 116 T (Denner et al, 2001;Bozal et al, 2003); 4, P. aquimaris SW-210 T (Yoon et al, 2005); 5, P. pacificensis (data for six strains) (Maruyama et al, 2000). Acid production from substrates and utilization of substrates were determined in this study under the same experimental conditions.…”
