[3] The third Alishewanella species was isolated from gajami sikhae, a Korean fermented food, in 2009 and was given the name A.

Alishewanella fetalis is a Gram-negative, non-motile, facultatively anaerobic, rod-shaped bacterium.

Also, having been initially isolated from an autopsy of a human fetus in 1992 in Sweden, it was given the species name fetalis.

[5] It is facultatively anaerobic and can utilize electron acceptors such as trimethylamine oxide (TMAO), nitrate, nitrite, and thiosulphate, but not sulphite or ferric iron.

[5] It shows a relationship to both Rheinheimara baltica through 16S rRNA,[6] and to the family Vibrionaceae through gyrase B.
