Draft Genome Sequences of Thalassobacter Strains 1CONIMAR09 and 16PALIMAR09, Two Members of the Roseobacter Lineage Isolated from Coastal Areas of the Mediterranean Sea around Mallorca Island.

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.

Draft Genome Sequences of Two Isolates of the Roseobacter Group, Sulfitobacter sp. Strains 3SOLIMAR09 and 1FIGIMAR09, from Harbors of Mallorca Island (Mediterranean Sea).

We present the draft genome sequences of two isolates of the Roseobacter lineage, 3SOLIMAR09 and 1FIGIMAR09, which were obtained from harbors of Mallorca Island, Spain, and are affiliated with the Sulfitobacter genus. Both isolates harbor the complete gene set for protocatechuate catabolism and incomplete pathways for several additional monoaromatic compounds.

Draft genome sequence of Citreicella aestuarii strain 357, a member of the Roseobacter clade isolated without xenobiotic pressure from a petroleum-polluted beach.

Citreicella aestuarii 357 is a member of the Roseobacter clade that was isolated without xenobiotic pressure from an oil-polluted sand sample from the Galician coast (Spain). Its genome sequence suggests an organoheterotrophic metabolism, including a wide catabolic potential for aromatic hydrocarbons.

Shotgun nanoLC-MS/MS proteogenomics to document MALDI-TOF biomarkers for screening new members of the Ruegeria genus.

The identification of bacteria by means of matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry directly using whole cells has become a standard method in clinical diagnosis due to its rapidity and simplicity. Nevertheless, the analysis of environmental samples with this approach still represents a challenge due to the enormous microbial diversity existing on earth and the lack of a comprehensive database. Most of the environmentally relevant species comprise only one unique strain, while pathogens such as Escherichia coli, with 667 described strains, are well documented.

Comparative proteogenomics of twelve Roseobacter exoproteomes reveals different adaptive strategies among these marine bacteria.

Roseobacters are generalist bacteria abundantly found in the oceans. Because little is known on how marine microorganisms interact in association or competition, we focused our attention on the microbial exoproteome, a key component in their interaction with extracellular milieu. Here we present a comparative analysis of the theoretically encoded exoproteome of twelve members of the Roseobacter group validated by extensive comparative proteogenomics.

Anthropogenic perturbations in marine microbial communities.

Human activities impact marine ecosystems at a global scale and all levels of complexity of life. Despite their importance as key players in ecosystem processes, the stress caused to microorganisms has been greatly neglected. This fact is aggravated by difficulties in the analysis of microbial communities and their high diversity, making the definition of patterns difficult.
