Proteorhodopsin in the ubiquitous marine bacterium SAR11
TLDR
SAR11 strain HTCC1062 (‘Pelagibacter ubique’), the first cultivated member of the extraordinarily abundant SAR11 clade, expresses a proteorhodopsin gene when cultured in autoclaved seawater and in its natural environment, the ocean, which functions as a light-dependent proton pump. Expand
The small genome of an abundant coastal ocean methylotroph.
TLDR
The genome sequence and metabolic properties of the first axenic isolate of the OM43 clade, strain HTCC2181, are reported, finding that this strain is an obligate methylotroph that cannot oxidize methane but can use the oxidized C1 compounds methanol and formaldehyde as sources of carbon and energy.

Lentisphaera araneosa gen. nov., sp. nov, a transparent exopolymer producing marine bacterium, and the description of a novel bacterial phylum, Lentisphaerae.
TLDR
Two phylogenetically distinct marine strains producing transparent exopolymers (TEP) were cultivated from Oregon coast seawater by dilution to extinction in a high throughput culturing format and consistently formed a new phylum-level lineage within the domain Bacteria. Expand
Pelagibaca bermudensis gen. nov., sp. nov., a novel marine bacterium within the Roseobacter clade in the order Rhodobacterales.
TLDR
A novel genus and species, Pelagibaca bermudensis gen. nov., sp.nov. Expand
Temporal and spatial response of bacterioplankton lineages to annual convective overturn at the Bermuda Atlantic Time‐series Study site
TLDR
Overall increases in the relative abundance of T-RFLP fragments attributable to the OCS116, SAR11, and marine Actinobacteria clusters following convective overturn suggest that members of these groups may play important roles in dissolved organic carbon dynamics at BATS. Expand
Cultivation and Growth Characteristics of a Diverse Group of Oligotrophic Marine Gammaproteobacteria
TLDR
This cultivation study revealed that sporadically detected Gammaproteobacteria gene clones from seawater are part of a phylogenetically diverse constellation of organisms mainly composed of oligotrophic and ultramicrobial lineages that are culturable under specific cultivation conditions. Expand
Maritimibacter alkaliphilus gen. nov., sp. nov., a genome-sequenced marine bacterium of the Roseobacter clade in the order Rhodobacterales.
TLDR
On the basis of the taxonomic data obtained in this study, strain HTCC2654(T) represents a novel genus and species, for which the name Maritimibacter alkaliphilus gen. nov., sp. Expand
The SAR92 Clade: an Abundant Coastal Clade of Culturable Marine Bacteria Possessing Proteorhodopsin
TLDR
Genome sequencing and analysis of HTCC2207 showed that the PR gene is present as a lone transcriptional unit directly followed by an operon containing genes that are presumably involved in the synthesis of retinal, the chromophore of PR. Expand
Puniceicoccus vermicola gen. nov., sp. nov., a novel marine bacterium, and description of Puniceicoccaceae fam. nov., Puniceicoccales ord. nov., Opitutaceae fam. nov., Opitutales ord. nov. and
TLDR
It is proposed that the new marine isolate was isolated from the digestive tract of a marine clamworm, Periserrula leucophryna, be placed into a novel genus and species named Puniceicoccus vermicola gen. nov in the class Opitutae. Expand
Polyphyletic photosynthetic reaction centre genes in oligotrophic marine Gammaproteobacteria.
TLDR
The findings identify the OM60 clade as a source of Gammaproteobacteria AAP genes in coastal oceans, and demonstrate that aerobic, anoxygenic photosynthetic metabolism can enhance the productivity of marine oligotrophic bacteria that also grow heterotrophically in darkness. Expand
