Observed frequency-independent torque in flagellar bacterial motors optimizes space exploration [PDF]
A surprising feature of many bacterial motors is the apparently conserved form of their torque-frequency relation. Experiments indicate that the torque provided by the bacterial rotary motor is approximately constant over a large range of angular speeds.

Extending Seqenv: a taxa-centric approach to environmental annotations of 16S rDNA sequences [PDF]
Understanding how the environment selects a given taxon and the diversity patterns that emerge as a result of environmental filtering can dramatically improve our ability to analyse any environment in depth as well as advancing our knowledge on how the ...

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]
Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

Temporal variability of diazotroph community composition in the upwelling region off NW Iberia. [PDF]
Knowledge of the ecology of N2-fixing (diazotrophic) plankton is mainly limited to oligotrophic (sub)tropical oceans. However, diazotrophs are widely distributed and active throughout the global ocean.

Structural Changes During Lysis of a Psychrophilic Marine Bacterium [PDF]
The marine psychrophile, a red, gram-negative motile rod with a single polar flagellum, is stable when suspended in 0.1 m Mg 2+ plus 0.5 m NaCl at 0 C and neutral p H but lyses if the salt composition of the medium is changed, the temperature ...

Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals [PDF]
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.
