De novo fatty acid synthesis controls the fate between regulatory T and T helper 17 cells
Results indicate fundamental differences between TH17 cells and Treg cells regarding their dependency on ACC1-mediated de novo fatty acid synthesis, which might be exploited as a new strategy for metabolic immune modulation of TH17 cell–mediated inflammatory diseases.

A new genus and species, Alcanivorax borkumensis, is described to include six heterotrophic bacterial strains isolated from enriched mixed cultures, obtained from sea water/sediment samples collected near the isle of Borkum (North Sea), using Mihagol-S (C14,15-n-alkanes) as principal carbon source.
Phylogeny and polyphasic taxonomy of Caulobacter species. Proposal of Maricaulis gen. nov. with Maricaulis maris (Poindexter) comb. nov. as the type species, and emended description of the genera…
A polyphasic approach, comprising 16S rDNA sequencing, profiling restriction fragments of 16S-23S r DNA interspacer regions, lipid analysis, immunological profiling and salt tolerance characterizations, was used to clarify the taxonomy of 76 strains of the genera Caulobacter.

It is revealed that the isotope ratio is independent of the growth stage and that most microorganisms showed enrichment of C16:0 with 13C when growing on glycerol, important for the calibration of a new method in which δ13C values of fatty acids from the environment delineate the use of bacterial substrates in an ecosystem.
Ferroplasma acidiphilum gen. nov., sp. nov., an acidophilic, autotrophic, ferrous-iron-oxidizing, cell-wall-lacking, mesophilic member of the Ferroplasmaceae fam. nov., comprising a distinct lineage…
An isolate of an acidophilic archaeon, strain YT, was obtained from a bioleaching pilot plant and showed this strain to cluster phylogenetically within the order 'Thermoplasmales' sensu Woese, although with only 89.9% sequence identity to its closest relatives, Picrophilus oshimae and Thermoplasma acidophilum.
Identification of the metabolically active members of a bacterial community in a polychlorinated biphenyl-polluted moorland soil.
The presumptive metabolically active members of a bacterial community in a moorland soil in Germany, highly polluted with polychlorinated biphenyls (PCBs), were identified by sequencing of cloned…
Thalassolituus oleivorans gen. nov., sp. nov., a novel marine bacterium that obligately utilizes hydrocarbons.
16S rRNA gene sequence analysis revealed that this isolate represents a distinct phyletic lineage within the gamma-Proteobacteria and has about 94.4% sequence similarity to Oceanobacter kriegii (the closest bacterial species with a validly published name).
Oleispira antarctica gen. nov., sp. nov., a novel hydrocarbonoclastic marine bacterium isolated from Antarctic coastal sea water.
A novel genus and species within the gamma-Proteobacteria are proposed, Oleispira antarctica gen. nov., sp.

Oceanicaulis alexandrii gen. nov., sp. nov., a novel stalked bacterium isolated from a culture of the dinoflagellate Alexandrium tamarense (Lebour) Balech.
Five bacterial strains isolated from a non-toxigenic strain of the marine dinoflagellate Alexandrium tamarense (Lebour) Balech CCMP 116 (NEPCC C116) are proposed to comprise a new species of a new genus, Oceanicaulis alexandrii gen. nov., sp.
