Strain CECT 7735T, a marine Gram-reaction negative, aerobic, non-motile bacterium, was isolated from coastal seawater in Valencia, Spain. Strain CECT 7735T is chemoorganotrophic, mesophilic, slightly halophilic, grows at 15–28 °C but not at 4 or 37 °C, requires seawater for growth and grows up to 6 % salinity. The major cellular fatty acid is summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c). The G+C content of the genome is 55.7 mol%. Comparative analysis of the 16S rRNA gene sequence shows the strain is affiliated to the family Rhodobacteraceae , in the class Alphaproteobacteria , with highest similarities to Phaeobacter species (97.0–97.5 %), Shimia species (96.5–97.3 %) and Pseudopelagico…
Draft genome sequence of Thalassobius mediterraneus CECT 5383T, a poly-beta-hydroxybutyrate producer
2016
Thalassobius mediterraneus is the type species of the genus Thalassobius and a member of the Roseobacter clade, an abundant representative of marine bacteria. T. mediterraneus XSM19T (=CECT 5383T) was isolated from the Western Mediterranean coast near Valencia (Spain) in 1989. We present here the draft genome sequence and annotation of this strain (ENA/DDBJ/NCBI accession number CYSF00000000), which is comprised of 3,431,658 bp distributed in 19 contigs and encodes 10 rRNA genes, 51 tRNA genes and 3276 protein coding genes. Relevant findings are commented, including the complete set of genes required for poly-beta-hydroxybutyrate (PHB) synthesis and genes related to degradation of aromatic …
Comparative Genomics of Thalassobius Including the Description of Thalassobius activus sp. nov., and Thalassobius autumnalis sp. nov.
2018
A taxogenomic study was conducted to describe two new Thalassobius species and to analyze the internal consistency of the genus Thalassobius along with Shimia and Thalassococcus. Strains CECT 5113T, CECT 5114, CECT 5118T, and CECT 5120 were isolated from coastal Mediterranean seawater, Spain. Cells were Gram-negative, non- motile coccobacilli, aerobic chemoorganotrophs, with an optimum temperature of 26°C and salinity of 3.5–5%. Major cellular fatty acids of strains CECT 5113T and CECT 5114 were C18 : 1 ω7c/ω6c and C10 : 0 3OH, G+C content was 54.4–54.5 mol% and were able to utilize propionate, L-threonine, L- arginine, and L-aspartate as carbon sources. They exhibited 98.3% 16S rRNA gene s…
Thalassobius mediterraneus gen. nov., sp. nov., and reclassification of Ruegeria gelatinovorans as Thalassobius gelatinovorus comb. nov.
2005
A Gram-negative, slightly halophilic, non-pigmented, strictly aerobic, chemo-organotrophic bacterium was isolated from sea water off the western Mediterranean coast near Valencia (Spain). This strain was able to grow on several organic acids and amino acids added to a minimal medium as carbon sources, but used few carbohydrates or yielded slight growth when sugars were used. Phylogenetic analysis based on an almost complete 16S rRNA gene sequence revealed that strain XSM19T was a member of the Roseobacter group within the ‘Alphaproteobacteria’, with its closest phylogenetic neighbour being Ruegeria gelatinovorans (97·6 % sequence similarity). Following a polyphasic approach, it was conclude…
