Signature Arsenic Detoxification Pathways in Halomonas sp. Strain GFAJ-1

Genome of halomonas strain GFAJ-1, a blueprint for fame or business as usual.

Draft genome of halomonas species strain GFAJ-1 (ATCC BAA-2256).

Halomonas strain GFAJ-1 was reported in Science magazine to be a remarkable microbe for which there was "arsenate in macromolecules that normally contain phosphate, most notably nucleic acids." The draft genome of the bacterium was determined (NCBI accession numbers AHBC01000001 through AHBC01000103). It appears to be a typical gamma proteobacterium.

Genome Sequence of Halomonas sp. Strain A3H3, Isolated from Arsenic-Rich Marine Sediments

We report the genome sequence of Halomonas sp. strain A3H3, a bacterium with a high tolerance to arsenite, isolated from multicontaminated sediments of the l'Estaque harbor in Marseille, France. The genome is composed of a 5,489,893-bp chromosome and a 157,085-bp plasmid.

Expression dynamics of arsenic respiration and detoxification in Shewanella sp. strain ANA-3.

Because arsenate [As(V)] reduction by bacteria can significantly enhance arsenic mobility in the environment, it is important to be able to predict when this activity will occur. Currently, two bacterial systems are known that specifically reduce As(V), namely, a respiratory system (encoded by the arr genes) and a detoxification system (encoded by the ars genes). Here we analyze the conditions ...

Halomonas gomseomensis sp. nov., Halomonas janggokensis sp. nov., Halomonas salaria sp. nov. and Halomonas denitrificans sp. nov., moderately halophilic bacteria isolated from saline water.

A total of 34 Halomonas strains were isolated from saline water in Anmyeondo, Korea. Ten of these strains, considered to belong to novel species, were subjected to a polyphasic taxonomic investigation. The strains were Gram-negative, moderately halophilic, motile and non-spore-forming rods that contained Q-9 as the predominant ubiquinone and C(18 : 1)omega7c, C(16 : 0) and either summed feature...
