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.
Genome sequence of the ubiquitous hydrocarbon-degrading marine bacterium Alcanivorax borkumensis
The genome sequence provides the basis for the future design of strategies to mitigate the ecological damage caused by oil spills and provides A. borkumensis SK2 with a competitive edge in oil-polluted environments.

Purified lichenysin A decreases the surface tension of water from 72 mN/m to 28 mN /liter and achieves the critical micelle concentration with as little as 12 mg/liter, characterizing the product as a powerful surface-active agent that compares favorably to others surfactants.

The exceptional chaotropicity of MgCl(2) is document here, and it is shown that this property, rather than water activity reduction, inhibits life by denaturing biological macromolecules, in hypersaline environments.
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.

It is hypothesized that extreme environments may exert a high selection pressure possibly resulting in the evolution of an exceptional and distinctive assemblage of protists in the deep hypersaline anoxic basins in the Mediterranean Sea.
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).
Novel Polyphenol Oxidase Mined from a Metagenome Expression Library of Bovine Rumen
Kinetic, electrochemical, and EPR analyses provide unequivocal evidence that the hypothetical proteins from Bacteroides thetaiotaomicron and from E. coli, which are closely related to the deduced protein encoded by the RL5 gene, are also multicopper proteins with polyphenol oxidase activity.
Stratified prokaryote network in the oxic–anoxic transition of a deep-sea halocline
A 2.5-m-thick chemocline with a steep NaCl gradient at 3.3 km within the water column betweeen Bannock anoxic hypersaline brine and overlying sea water is reported, supporting some of the most biomass-rich and active microbial communities in the deep sea.
