Anaerobic activation of the entire denitrification pathway in Pseudomonas aeruginosa requires Anr, an analog of Fnr
Results indicate that the anr gene product plays a key role in anaerobically activating the entire denitrification pathway.

A phylogenetic tree based on 16S rRNA gene sequences showed that strain WPCB118(T) had an evolutionary lineage within the radiation encompassing the members of the family 'Flexibacteraceae', its closest neighbour being Spirosoma linguale LMG 10896(T ) (93.7 % gene sequence similarity).
Genetic and phenotypic diversity of 2,4-dichlorophenoxyacetic acid (2,4-D)-degrading bacteria isolated from 2,4-D-treated field soils
Forty-seven numerically dominant 2,4-dichlorophenoxyacetic acid (2, 4-D)-degrading bacteria were isolated at different times from 1989 through 1992 from eight agricultural plots, and these isolates were strains of Sphingomona, Pseudomonas, or Alcaligenes species.

The results of DNA-DNA hybridization and the phenotypic data showed that strains 5420S-12(T) and 5420 S-16(T), isolated from air samples, could be distinguished from phylogenetically related species and represent two novel species within the genus Microvirga, for which the names MicrovirGA aerophila sp.

It is suggested that the bacteria belonging to the phylum Acidobacteria might be numerically dominant as well as metabolically active in the soil sample, implying that the ph Asylum Acidob bacteria might be highly involved in the biogeochemical cycles of the rhizosphere soil.
Altererythrobacter namhicola sp. nov. and Altererythrobacter aestuarii sp. nov., isolated from seawater.
Two non-motile, orange- or yellow-pigmented bacteria, designated strains KYW48(T) and KYW147(T), were isolated from seawater collected from the South Sea, Republic of Korea and a phylogenetic tree based on 16S rRNA gene sequences showed that strains were grouped with the members of the family Erythrobacteraceae and formed a distinct clade with theMembers of the genus AltererythRobacter.
Pedobacter namyangjuensis sp. nov. isolated from soil and reclassification of Nubsella zeaxanthinifaciens Asker et al. 2008 as Pedobacter zeaxanthinifaciens comb. nov.

Chemotaxonomic characteristics of the novel strains, including DNA G+C content of genomic DNA (37.0 mol%), the predominant respiratory quinine (MK-7), and the major fatty acids which were iso-C15:0, summed feature 3, are similar to those of the genus Pedobacter, however, the novel strain can be distinguished from the other species of Pedobacteria by physiological properties.
Effects of diverse water pipe materials on bacterial communities and water quality in the annular reactor.
Steel pipe exhibited the highest bacterial diversity among the metallic pipes, and the DGGE profile of biofilm on PVC showed three additional bands not detected from the profiles of the metallic materials.
