History
The family was originally described in 1988 to contain the genera ''Halomonas'' and ''Deleya''. In 1989, ''Chromobacterium marismortui'' was reclassified as ''Chromohalobacter marismortui'' forming a third genus in the family Halomonadaceae. Subsequently, in 1990 a species was discovered and was originally proposed to be called ''Volcaniella eurihalina'' forming a new genus in the ''Halomonadaceae'', but was later (in 1995) reclassified as a member of the genus ''Halomonas''. The species ''Carnimonas nigrificans'' (sole member of genus) was not placed in the family due to the lack of two out of 15 descriptive 16S rRNA signature sequences, but it has been proposed to reclassify it into the family. In 1996, the family was later reorganised by unifying genera ''Deleya'', ''Halomonas'' and ''Halovibrio'' and the species ''Paracoccus halodenitrificans'' into ''Halomonas'' and placing ''Zymobacter'' in this family. However, it was later discovered that the strain of ''Halovibrio variabilis'' DSM 3051 and DSM 3050 differed and the latter was made type strain of the ''Halovibrio'', which remains still in use. and now comprising two species (the other being Halovibrio denitrificans) In 2002, ''Halomonas marina'' was transferred to its own genus ''Cobetia'', and in 2009 ''Halomonas marisflavi'', ''Halomonas indalinina''. and ''Halomonas avicenniae'' were transferred to a new genus called ''Kushneria'' (5 species) Several singleton genera were created recently: in 2007, ''Halotalea alkalilenta'' was described, ''Aidingimonas halophila'' in 2009, ''Halospina denitrificans'' in 2006, ''Modicisalibacter tunisiensis'' in 2009 ''Salinicola socius'' in 2009. To the latter genus two species were transferred ''Halomonas salaria'' as '' Salinicola salarius'' and ''Chromohalobacter salarius'' as '' Salinicola halophilus''. The family also contain the recently discovered but uncultured bacterium "Genera
* ''Halomonas'', the type genus ** ''Halomonas elongata'', the type species of the genus, however the longest known members of the family are ''Halomonas halodentrificans'' (1952), ''Chromohalobacter marismortui'' (1940) and ''Chromohalobacter beijerinckii'' (originally ''Pseudomonas beijerinckii''). ** ''Halomonas titanicae'' * ''Aidingimonas halophila'' * ''Cobetia'' ** '' Cobetia marina'', originally ''Pseudomonas marina'', then ''Dalya marina'', then ''Halomonas marina''. ** '' Cobetia crustatorum'', isolated from fermented Korean seafood * ''Carnimonas'' * ''Chromohalobacter'' ** ''Chromohalobacter marismortui'' ** ''Chromohalobacter beijerinckii'' ** ''Chromohalobacter canadensis'' and ''Chromohalobacter israelensis'', formerly of the genus ''Halomonas'' ** ''Chromohalobacter japonicus'' ** ''Chromohalobacter nigrandesensis'' ** ''Chromohalobacter salarius'' ** ''Chromohalobacter salexigens'' ** ''Chromohalobacter sarecensis'', phychrotolerant * ''Halotalea alkalilenta'' * ''Kushneria'' ** ''Kushneria aurantia'', type species ** ''Kushneria marisflavi'', ''Kushneria indalinina'' and ''Kushneria avicenniae'' were previously classified under ''Halomonas'' * ''Modicisalibacter'' * ''Portiera'' * ''Zymobacter'', not to be confused with '' Zymomonas mobilis'', an alphaproteobacterion studies for its biofuel production, an easy error that even theEtymology
