Abstract

We report the draft genome sequence of two new members of the Roseobacter lineage, Thalassobacter strains 1CONIMAR09 and 16PALIMAR09, which were isolated from the seawater coast of Mallorca Island. Each genome harbored putative genes for obtaining energy by chemolithotrophy and making aerobic anoxygenic photosynthesis.

Highlights

Two strains of the genus Thalassobacter were isolated from the Mediterranean Sea on Mallorca Island, Spain, in March of 2009 by direct plating on marine broth agar [4]
The results of average nucleotide identity based on BLAST (ANIb) [6] showed that the two strains were members of the same species (99.5% genome identity)
The rRNA operon was divided into two different contigs whose fold coverage (141-fold) suggested that there is probably a minimum of two rRNA operons

Summary

Introduction

The Roseobacter lineage (Rhodobacteraceae family) is a generalist, diverse, and ubiquitous phylogenetically coherent group and is considered to be a significant component of bacterioplankton (up to 20%) [1, 2]. Given these features and their ecological relevance, the genomes of an increasing number of Roseobacter isolates have been sequenced. Two strains of the genus Thalassobacter were isolated from the Mediterranean Sea on Mallorca Island, Spain, in March of 2009 by direct plating on marine broth agar [4]. 16S rRNA gene analysis suggested that both strains affiliate with Thalassobacter stenotrophicus species (99.79% identity with CECT 5294T).
