Draft genome sequence of Thalassobius mediterraneus CECT 5383 T , a poly-beta-hydroxybutyrate producer

Abstract

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 compounds.

Draft Genome Sequence of the Putative Marine Pathogen Thalassobius sp. I31.1

“…Lesions are the characteristic symptom of epizootic shell disease (ESD), and Thalassobius has been indicated as a putative pathogen in lesion formation (1). Although Thalassobius strains may be unable to utilize various carbohydrates for growth (2), they can possess the ability to degrade the potential carcinogen phthalate, a chemical widely used in the manufacture of plastics, lubricants, and textiles (3). Such strains contain genes required for poly-β-hydroxybutyrate (PHB) synthesis and genes relating to the degradation of phenylacetates, an abundant class of environmental pollutants (4).…”

Comparative Genomics of Thalassobius Including the Description of Thalassobius activus sp. nov., and Thalassobius autumnalis sp. nov.

“…Whole genome drafts of T. mediterraneus and T. gelatinovorus and S. marina type strains have been determined and characterized in the last two years (Rodrigo-Torres et al, 2016a , b , 2017 ). Also, Nogales and co-workers have explored the phylogenomics of a large collection of the Roseobacter group members, including several type strain genomes, by using more than a 100 single copy protein coding genes and found four Thalassobius species forming a well-defined lineage, which includes Shimia species (unpublished, Nogales et al, 2017, FEMS Meeting of European Microbiologists).…”
