Halomonas

Halomonas is a genus of halophilic (salt-tolerating) proteobacteria. It grows over the range of 5 to 25% NaCl.
The type species of this genus is "Halomonas elongata".
Description.
Members of "Halomonas" are Gram-negative, rod-shaped bacteria, generally 0.6-0.8 μm by 1.6-1.9 μm. They move by using flagella. They grow in the presence of oxygen, although some have been reported to be able to grow without oxygen. When grown on an agar plate, they form white/yellow colonies that turn light brown over time.
Ecology.
"Halomonas" species have been found in a broad variety of saline environments, including estuaries, the ocean, and saline lakes.

Pathogenic potential.
Certain species of "Halomonas "may display pathogenic potential in humans. In one study, three species were isolated from two patients suffering bacteremia in a dialysis center. The study hypothesized that the bicarbonate used in the dialysis fluid may have been contaminated by the bacteria.
Etymology.
The name "Halomonas" derives from: Greek noun "hals, halos" (ἅλς, ἁλός), salt; and "monas" (μονάς), nominally meaning "a unit", but in effect meaning a bacterium; thus, salt (-tolerant) monad.
Members of the genus "Halomonas" can be referred to as halomonads (see Trivialisation of names).
