“…T was menaquinone-7 (MK-7), which is compatible with that of F. kasyanovii and F. imtechensis (Nedashkovskaya et al, 2007;Nupur et al, 2012). The major fatty acids (>10 % of the total fatty acids) found in strain TM-6 T were iso-C 15 : 0 , iso-C 15 : 1 G and iso-C 17 : 0 3-OH ( Table 2).…”

A Gram-stain-negative, non-flagellated, non-gliding and rod-shaped bacterial strain, designated TM-6 T , was isolated from a tidal flat sediment in the Korean peninsula. Strain TM-6 T was found to grow optimally at pH 7.0-8.0, at 30 C and in the presence of 2-3% (w/v) NaCl. A neighbour-joining phylogenetic tree based on 16S rRNA gene sequences showed that strain TM-6 T joined the clade comprising recognized species of the genus Fulvivirga, with which it exhibited 94.7-95.2 % sequence similarity. Strain TM-6 T was found to contain iso-C 15 : 0 , iso-C 15 : 1 G and iso-C 17 : 0 3-OH as major fatty acids. The only isoprenoid quinone was menaquinone-7 (MK-7). The major polar lipids were identified as phosphatidylethanolamine and three unidentified lipids. The DNA G+C content of strain TM-6 T was 50.9 mol%. Differential phenotypic properties, together with the phylogenetic distinctiveness, revealed that strain TM-6

“…The genus Fulvivirga, a member of the family Flammeovirgaceae (phylum Bacteroidetes), was established by Nedashkovskaya et al (2007) with the description of Fulvivirga kasyanovii, isolated from seawater in a mussel farm, as the sole validly published species. Subsequently, Fulvivirga imtechensis (Nupur et al, 2012) has been described.…”

“…The predominant menaquinone (MK-7) detected in strains 3B-2 T and 10AO T is the same as found in all members of the phylum Bacteroidetes used in the phylogenetic analysis (Nakagawa et al , 1997; Nedashkovskaya et al , 2004, 2005, 2006, 2007; Vancanneyt et al , 2006; Weon et al , 2006; Vaz-Moreira et al , 2007; Finster et al , 2009; Srisukchayakul et al , 2007; Tang et al , 2009). Strains 3B-2 T and 10AO T could not be differentiated clearly from other members of the phylum Bacteroidetes based on their fatty acid profiles, but their fatty acid profiles showed differences in the nature and proportion of the major fatty acid(s) compared with several genera used in the phylogenetic analysis (Bowman et al , 2003; Brettar et al , 2004; Nedashkovskaya et al , 2005, 2006, 2007; Schmidt et al , 2006; Ying et al , 2006; Arun et al , 2009; Liu et al , 2009). The levels of 16S rRNA gene sequence similarity between strains 3B-2 T and 10AO T and other bacterial taxa were sufficient to differentiate these novel strains from previously known genera of the phylum Bacteroidetes .…”

Two Gram-stain-negative, non-motile, non-spore-forming, rod-shaped bacterial strains, designated 3B-2T and 10AOT, were isolated from a sand sample collected from the west coast of the Korean peninsula by using low-nutrient media, and their taxonomic positions were investigated in a polyphasic study. The strains did not grow on marine agar. They grew optimally at 30 °C and pH 6.5–7.5. Strains 3B-2T and 10AOT shared 97.5 % 16S rRNA gene sequence similarity and mean level of DNA–DNA relatedness of 12 %. In phylogenetic trees based on 16S rRNA gene sequences, strains 3B-2T and 10AOT, together with several uncultured bacterial clones, formed independent lineages within the evolutionary radiation encompassed by the phylum Bacteroidetes. Strains 3B-2T and 10AOT contained MK-7 as the predominant menaquinone and iso-C15 : 0 and C16 : 1ω5c as the major fatty acids. The DNA G+C contents of strains 3B-2T and 10AOT were 42.8 and 44.6 mol%, respectively. Strains 3B-2T and 10AOT exhibited very low levels of 16S rRNA gene sequence similarity (<85.0 %) to the type strains of recognized bacterial species. These data were sufficient to support the proposal that the novel strains should be differentiated from previously known genera of the phylum Bacteroidetes. On the basis of the data presented, we suggest that strains 3B-2T and 10AOT represent two distinct novel species of a new genus, for which the names Ohtaekwangia koreensis gen. nov., sp. nov. (the type species; type strain 3B-2T = KCTC 23018T = CCUG 58939T) and Ohtaekwangia kribbensis sp. nov. (type strain 10AOT = KCTC 23019T = CCUG 58938T) are proposed.

“…Fluctuations in other bacteria commonly associated with the water column, sediment or fish and shellfish farms, suggest that water fluxes during this period may also have played an important role in modulating the coral microbial community. The nearby coastline supports both oyster and fish farms, and two of the bacteria detected with a high frequency on Day 2 in *4-yr-old corals have been formerly associated with shellfish farms (Fulvivirga) and fish diseases (Piscirickettsiaceae) (Nedashkovskaya et al 2007;Rozas and Enríquez 2014). It has been proposed that the microbiome can be separated into microbes that can be classed as 'transient' and more sporadic versus those that are more stable or sometimes referred to as 'core' members (Ainsworth et al 2015;Hester et al 2015;Sweet and Bulling 2017).…”

Evidence for rapid, tide-related shifts in the microbiome of the coral Coelastrea aspera

et al. 2017

View full text Add to dashboard Cite

Shifts in the microbiome of the intertidal coral Coelastrea aspera (formally known as Goniastrea aspera) from Phuket, Thailand, were noted over the course of a 4-d period of spring tides. During this time, corals were naturally exposed to high temperatures, intense solar radiation, sub-aerial exposure and tidally induced water fluxes. Analysis of the 16S microbiome highlighted that the corals harbored both 'core or stable' communities and those which appeared to be more 'transient or sporadic.' Only relatively few microbial associates were classified as core microbes; the majority were transient or sporadic. Such transient associates were likely to have been governed by tidally induced variations in mucus thickness and water fluxes. Here we report strong shifts in the bacterial community of C. aspera over a short temporal scale. However, we also show significant differences in the timing of shifts between the two age groups of corals studied. More rapid changes (within 2 d of sub-aerial exposure) occurred within the 4-yr-old colonies, but a slightly delayed response was observed in the 10-yr-old colonies, whereby the microbial associates only changed after 4 d. We hypothesize that these shifts are age related and could be influenced by the observed baseline differences in the microbiome of the 4-and 10-yr-old corals, bacteria-bacteria interactions, and/or host energetics.
