Algoriphagus ratkowskyi gen. nov., sp. nov., Brumimicrobium glaciale gen. nov., sp. nov., Cryomorpha ignava gen. nov., sp. nov. and Crocinitomix catalasitica gen. nov., sp. nov., novel flavobacteria isolated from various polar habitats

Description of Algoriphagus aquimarinus sp. nov., Algoriphagus chordae sp. nov. and Algoriphagus winogradskyi sp. nov., from sea water and algae, transfer of Hongiella halophila Yi and Chun 2004 to the genus Algoriphagus as Algoriphagus halophilus comb. nov. and emended descriptions of the genera Algoriphagus Bowman et al. 2003 and Hongiella Yi and Chun 2004

“…The DNA G+C contents of the three marine strains KMM 3956 T , KMM 3957 T and KMM 3958 T were 42 (T m ) and 39 mol% (HPLC), 40 (T m ) and 37 mol% (HPLC) and 41 (T m ) and 41 mol% (HPLC), respectively. The values for A. ratkowskyi and H. halophila were 37 mol% (HPLC), similar to the values of 35-36 and 37 mol%, respectively, from the literature (Bowman et al, 2003;Yi & Chun, 2004).…”

“…The genus Algoriphagus was proposed by Bowman et al (2003) for heterotrophic, Gram-negative, non-motile, strictly aerobic, saccharolytic, rod-like, pink-pigmented and cold-adapted strains isolated from sea ice and from saline lake cyanobacterial mats collected in Antarctica. The genus is phylogenetically distantly related to the genus Cyclobacterium of the phylum Bacteroidetes and was represented by a single species Algoriphagus ratkowskyi with type strain IC025 T .…”

Roseivirga ehrenbergii gen. nov., sp. nov., a novel marine bacterium of the phylum ‘Bacteroidetes’, isolated from the green alga Ulva fenestrata

“…Lewin & Lounsbery (1969), Reichenbach (1989), Raj & Maloy (1990), Bowman et al (2003), Nedashkovskaya et al (2003bNedashkovskaya et al ( , 2004, Brettar et al (2004), Yi & Chun (2004), Yoon et al (2004), Van Trappen et al (2004) …”

“…A single strain of the dark-orange-pigmented agarolytic bacterium Reichenbachia agariperforans, inhabiting coastal waters of the Sea of Japan, was described (Nedashkovskaya et al, 2003b). Also, rose-pigmented representatives of the genera Algoriphagus and Hongiella have been recovered from different sources from saline lakes and marine environments (Bowman et al, 2003;Yi & Chun, 2004;Nedashkovskaya et al, 2004;Van Trappen et al, 2004). The pink-coloured bacterium Belliella baltica was isolated from surface water of the central Baltic Sea (Brettar et al, 2004).…”

Pontibacter akesuensis sp. nov., isolated from a desert soil in China

“…The majority of the members of the phylum Bacteroidetes have been isolated from seawater, sediment or algae. Some marine bacteria of the phylum Bacteroidetes possess menaquinone 7 (MK-7) as their main respiratory quinone (Bowman et al, 2003; Brettar et al, 2004a, b; Nedashkovskaya et al, , 2004 Nedashkovskaya et al, , 2005aRaj & Maloy, 1990;Van Trappen et al, 2004;Yi & Chun, 2004;Yoon et al, 2004Yoon et al, , 2005a. The present investigation was designed to establish the taxonomic position of a novel isolate that formed a common clade with the genus Pontibacter within the phylum Bacteroidetes.…”
