Croceicoccus marinus gen. nov., sp. nov., a yellow-pigmented bacterium from deep-sea sediment, and emended description of the family Erythrobacteraceae

“…Table 1. Phenotypic characteristics that differentiate strain E4A9 T from other related members of the family Erythrobacteraceae Strains/taxa: 1, strain E4A9 T ; 2, Altererythrobacter (Yoon et al, 2005b;Kwon et al, 2007); 3, Erythrobacter (Shiba & Simidu, 1982;Yurkov et al, 1994;Denner et al, 2002;Yoon et al, 2003Yoon et al, , 2004aYoon et al, , 2005aIvanova et al, 2005); 4, Erythromicrobium (Yurkov et al, 1994;Rainey et al, 2003); 5, Porphyrobacter (Fuerst et al, 1993;Hanada et al, 1997;Hiraishi et al, 2002;Rainey et al, 2003;Yoon et al, 2004bYoon et al, , 2006. Data refer to all species within the genera.…”

“…Ubiquinone-10 is the major respiratory quinone. Most species in the family have been isolated from various aquatic environments such as freshwater, seawater, marine mats or sediment, a hot spring, seaweed, a starfish and coral (Shiba & Simidu, 1982; Fuerst et al, 1993;Yurkov et al, 1994; Hanada et al, 1997; Denner et al, 2002; Hiraishi et al, 2002;Rainey et al, 2003;Yoon et al, 2003Yoon et al, , 2004a Yoon et al, , b, 2005a Yoon et al, , b, 2006Ivanova et al, 2005;Kwon et al, 2007). This study focuses on the description of strain E4A9 T , isolated from a deep-sea sediment sample.…”

Winogradskyella exilis sp. nov., isolated from the starfish Stellaster equestris, and emended description of the genus Winogradskyella

“…Medium B contained (w/v) 0.2 % Bacto peptone (Difco), 0.2 % casein hydrolysate (Merck), 0.2 % Bacto yeast extract (Oxoid), 0.1 % glucose, 0.02 % KH 2 PO 4 , 0.005 % MgSO 4 . 7H 2 O and 1.5 % Bacto agar (Oxoid) in 50 % (v/v) natural seawater and 50 % (v/v) distilled water at pH 7.5-7.8, as described elsewhere (Ivanova et al, 1996).The phenotypic properties used for the characterization of Flavobacterium species were determined by using standard procedures (Smibert & Krieg, 1994) and as described elsewhere (McMeekin et al, 1971;Ivanova et al, 1996Ivanova et al, , 1998Ivanova et al, , 2005Bernardet et al, 2002). Strain 022-2-26 T was cultured at 22-24 u C. To test for spreading growth and gliding motility, strain 022-2-26 T was grown on medium B with the peptone content reduced to 0.02 % (0.2 g l 21 ).…”

“…For the extraction and characterization of carotenoid pigments and menaquinones, phospholipids and fatty acids, cell biomass of strain 022-2-26 T was harvested from MA (five plates for carotenoid pigment analysis) after incubation at 28 u C for 48 h as described previously (Ivanova et al, 2005). Pigment extraction and characterization was performed as described previously (Ivanova et al, 2005).…”
