“…Phylogenetic analysis revealed the genus Kordiimonas to be closely related to the genera Eilatimonas and Temperatibacter (Teramoto & Nishijima, 2014). They can be distinguished from other groups within the class Alphaproteobacteria by their cellular fatty acid composition, having high contents of iso-and anteiso-branched fatty acids (Paramasivam et al, 2013;Teramoto & Nishijima, 2014;Xu et al, 2014). A novel Kordiimonas strain, M41 T , was isolated from a surface seawater sample collected from the western Pacific Ocean and was subjected to taxonomic study using a polyphasic approach.…”

A Gram-stain-negative, aerobic, rod-shaped bacterium, designated M41 T , was isolated from a surface seawater sample collected from the western Pacific Ocean. The isolate grew in medium containing 0.5-10.0 % (w/v) NaCl (optimally at 1.0-3.0 %) at 15-45 C and pH 5.5-9.5. Positive for oxidase, catalase and nitrate reduction. The respiratory quinone is Q-10. The major fatty acids (>10 %) are iso-C 15:0 , iso-C 17:1 !9c and summed feature 3 (comprising C 16:1 !7c and/or iso-C 15:0 2-OH). The major polar lipids are phosphatidylethanolamine, one unidentified phospholipid, one unidentified aminolipid, and three unidentified glycolipids.The genomic DNA G +C content is 56.3 mol %. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain M41 T should be assigned to the genus Kordiimonas. The 16S rRNA gene sequence similarities between the isolate and the type strains of species of the genus Kordiimonas with validly published names were in the range 96.2-98.6 %. Strain M41 T exhibited average nucleotide identity (ANI) values of 81.7 and 72.3 % with respect to Kordiimonas. lacus S3-22 T and Kordiimonas gwangyangensis JCM 12864 T , respectively. The genome-to-genome distance analysis revealed that strain M41 T shared 51.4 % DNA-DNA relatedness with K. lacus S3-22 T and 16.3 % with K. gwangyangensis JCM 12864 T . On the basis of phenotypic and genotypic characteristics, strain M41 T represents a novel species of the genus Kordiimonas, for which the name Kordiimonas lipolytica sp. nov. is proposed. The type strain is M41 T (=CGMCC 1.15304 T =JCM 30877 T ). An emended description of Kordiimonas lacus is also provided.

“…Differences between 2011 and 2012 are significant at 0.5 and 2.5 m (p = 0.016 and p = 0.014, respectively). The difference between 0.5 and 2.5 m depth is significant (p < 0.001) Paramasivam et al (2012) showed that, while the gross morphology of the white spots is characterized by seemingly bleached tissue, the spots underwent some tissue necrosis, release of zooxanthellae, and symbiophagy (e.g. digestion of the zooxanthellae by their host; see Downs et al 2009).…”

We previously reported the sudden emergence of a disease-like syndrome in which numerous circular white spots were observed in Millepora dichotoma colonies in the Gulf of Aqaba (Zvuloni et al. 2011; Mar Ecol Prog Ser 441:25−32) and termed this phenomenon Multifocal Bleaching (MFB). Carlson (2012; Mar Ecol Prog Ser 463:297−299), based on his observations from Hawaiian coral reefs, suggests that the MFB is caused through foraging by the blenny Exallias brevis. Carlson's suggestion led us to perform new field and laboratory studies to confirm or discount this possibility. We were unable to document biting of the hydrocorals by E. brevis in the field, but our aquarium experiment demonstrated that the white spots are indeed a direct result of the blenny's biting. In addition, we found a strong linkage between the presence of E. brevis and the presence of MFB in M. dichotoma colonies. We accept Carlson's suggestion, which leads to the following questions: (1) Is the sudden emergence of MFB in the Red Sea caused by a sudden surge in the population of E. brevis? (2) Has a change in environmental conditions prompted E. brevis to suddenly begin feeding on M. dichotoma? (3) What will be the long-term impact of E. brevis on populations of M. dichotoma, an important component of shallow reefs in the Red Sea?

A Gram-stain-negative, motile, mesophilic, aerobic, rod-shaped bacterium, strain 5-11 T , was isolated from surface seawater at Muroto city, Kochi prefecture, Japan. The strain exhibited a narrow growth temperature range of 20-30 6C. Phylogenetic analyses based on 16S rRNA gene sequences showed that the strain fell within the order Kordiimonadales in the class Alphaproteobacteria and was related most closely to the genus Kordiimonas (up to 91.2 % similarity to the type strains of species of the genus) but branched deeply from species of Kordiimonas. The major fatty acids were iso-C 17 : 1 v9c, iso-C 15 : 0 , and C 16 : 1 v7c and/or iso-C 15 : 0 2-OH. Ubiquinone-10 (Q-10) was detected as the sole isoprenoid quinone. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and one unidentified aminolipid. Although strains of Kordiimonas have been shown to contain unidentified glycolipids, they were not detected from strain 5-11 T . The DNA G+C content of strain 5-11 T was 44.3 mol%, a value that was lower than those of strains of Kordiimonas (50-58 mol%) and was relatively low for the members of the class Alphaproteobacteria. On the basis of phenotypic, genotypic and chemotaxonomic data, it is proposed that strain 5-11 T represents a novel species of a new genus, Temperatibacter marinus gen. nov., sp. nov., within a new family Temperatibacteraceae fam. nov. The type strain of Temperatibacter marinus is 5-11 T (5NBRC 110045 T 5LMG 28278 T ).
