Bacteria of the Roseobacter clade show potential for secondary metabolite production. The microbial taxa, Pseudomonas aeruginosa PAO1 and Roseobacter denitrificans Och114, were chosen because they are well-characterized microbial species and can occur in marine habitats, which is a focus of our laboratory.

Overview of the marine Roseobacter lineage. Hence, these bacteria use quorum sensing to regulate phenotypic traits (e.g., biofilm formation, metabolite/toxin production, conjugation) when their populations in the marine snow environment reach adequate densities [318,319] . Roseobacter species and other environmental bacteria besides Vibrio associate with marine snow and also produce acyl homoserine lactones.

The first strain descriptions appeared in 1991 which described members Roseobacter litoralis and Roseobacter denitrificans, both pink-pigmented bacteriochlorophyll a-producing strains isolated from marine algae.

The Roseobacter lineage is a diverse group within Alphaproteobacteria that can represent up to 20% of marine microbial communities ().The catabolism of organic compounds (including aromatic hydrocarbons), sulfur and carbon monoxide oxidation, and aerobic anoxygenic photosynthesis are some important traits that can be found in this group (2 – 4).

Appl Environ Microbiol. The patchy distribution of photosynthesis gene clusters (PGCs) within this lineage probably results from horizontal transfers and this explanation is supported by two cases of plasmid‐located PGCs. 78 (4): 573 – 587. Members of the Roseobacter clade are equipped with a tremendous diversity of metabolic capabilities, which in part explains their success in so many different marine habitats. Marine Roseobacter are abundant, ubiquitous and diverse in the ocean and play active roles in global biogeochemical cycling, especially the sulfur cycle. Nature. ↵ Giebel HA, Brinkhoff T, Zwisler W, Selje N, Simon M. 2009. It contains spheroidenone, does not synthesize bacteriochlorophyll anaerobically, but shows aerobic phototrophic activity. Although Their broad metabolic versatility make roseobacters successful in a variety of habitats (4, 5). The Roseobacter lineage in the α-proteobacteria is abundant in southeastern U.S. estuaries (3, 15) and other coastal environments (27, 46).In the expansive salt marshes of the southeastern United States, where many Roseobacter strains have been isolated, organic matter is strongly influenced by naturally occurring aromatic compounds in the form of lignin and humic substances (25, 26). Roseobacter denitrificans is a species of aerobic pink-pigmented bacteria. Currently, 32 bacteriophages that infect multi-ple lineages of roseobacters have been isolated and sequenced. Environ. The isolation of phages that infect SAR11 and SAR116 have demonstrated the dominance of these phages in the marine virosphere. R. litoralis does not reduce nitrate, while R. denitrificans does. Many major marine bacterial lineages such as SAR11, Prochlorococcus , SAR116, and several Roseobacter lineages have members that are abundant, relatively slow-growing, and genome streamlined. Microbiol. Gulvik CA, Buchan A. Lateral gene transfer and the nature of bacterial innovation. Evolutionary ecology of the marine Roseobacter clade. The Roseobacter lineage is a phylogenetically coherent, physiologically heterogeneous group of alpha-Proteobacteria comprising up to 25% of marine microbial communities, especially in coastal and polar oceans, and it is the only lineage in which cultivated bacteria are closely related to environmental clones. Applied and environmental microbiology, 71(10), 5665–77. Buchan A, González JM, Moran MA (2005) Overview of the marine Roseobacter lineage. It is one of the most widely distributed and abundant bacterial groups in the marine ecosystem constituting up to 30% of bacterial communities in pelagic environments. Here we announce the genome sequence of a marine bacterium, HTCC2150, that was isolated off the Oregon coast using dilution-to-extinction culturing and that is affiliated with the Roseobacter clade.
