Abstract

Salegentibacter agarivorans sp. nov., a novel marine bacterium of the family Flavobacteriaceae isolated from the sponge Artemisina sp.

Salegentibacter chungangensis sp. nov., isolated from a sea sand and emended description of the genus Salegentibacter

“…The following fatty acids were also present to at least 1 %: summed feature 3 (C 16 : 1 v6c and/or C 16 : 1 v7c; 11.8 % iso-C 17 : 1 v9c (10.9 % anteiso-C 15 : 0 (9.3 %), iso-C 15 : 1 (9.3 %), iso-C 17 : 0 3-OH (7.9 %), iso-C 16 : 0 (4.1 %), iso-C 16 : 0 3-OH 1.0 % anteiso-C 17 : 1 v9c (3.2 %), iso-C 15 : 0 3-OH (3.2 %), C 17 : 1 v6c (2.3 %) and C 15 : 1 v6c (1.2 %). This fatty acid profile was similar to those of species of the genus Salegentibacter, although there were differences in the proportions of some fatty acids, probably because of differences in cultivation conditions (Nedashkovskaya et al, 2006); 4, Salegentibacter salarius ISL-6 T (Yoon et al, 2007); 5, Salegentibacter flavus KMM 6000 T (Ivanova et al, 2006). Fatty acids that represented ,1 % of the total in all strains are not shown.…”

Agarivorans gilvus sp. nov. isolated from seaweed

“…Many novel agardegrading bacterial species have been isolated from marine environments, where they occur as part of the indigenous flora. For example, Simiduia agarivorans, Aliagarivorans marinus, Aliagarivorans taiwanensis and Tamlana agarivorans were isolated from seawater samples (Shieh et al, 2008;Jean et al, 2009;Yoon et al, 2008); Psychromonas agarivorans, Microbulbifer agarilyticus and Marinimicrobium agarilyticum were found in marine sediment samples (Hosoya et al, 2009;Miyazaki et al, 2008;Lim et al, 2006); and Salegentibacter agarivorans was recovered from a species of sponge (Nedashkovskaya et al, 2006). The widespread occurrence of agar-degrading bacteria is probably best explained by their likely role in the carbon cycle involving the breakdown of agar and other sulfated galactans (Armisen & Galactas, 1987;Pomin, 2010), which form a significant component of the cell walls of red and green algae, the egg jelly coating of certain sea urchin species, and the outer tunics of ascidians (Pomin, 2010).…”
