Morphology Halovibrio variabilis
CELLULAR  
Staining Gram-negative;
Morphology vibrioid cells, having less than one complete helical turn singlely or in pairs

Specialized structures Many of the organisms become converted into thin-walled "coccoid bodies" in old cultures.
Division  
COLONIAL  
Solid surface colonies are ciruclar with entire margins, slimy, raised with a light brown colour
Liquid Growth on acetate, caproate, glutamine, valarate, esculin, glycerol, ethean, peptone and yeast extract
