Deleya halophila (also known as Halomonas halophila) is a salt-loving, gram-negative bacteria.[1] It is known to habitat marine environments, solar salterns, saline soils, and salted food. The genus was named after J. De Ley, a noted biologist. Its type strain is CCM 3662.

This particular species is anaerobic, rod-shaped and motile, thanks to possessing eight petritichous flagella. It grows optimally in 7.5% (wt/vol) sodium chloride solution. Albeit, salt shock is achieved with a concentration of 2-2.5M, affecting cell division and protein synthesis.[2] Its reaction to heat shock is also associated with the medium's salt concentration.[3]

This species is also a good exponent of biomineralisation, particularly precipitation of calcium carbonate.[4][5]
