The Halomonadaceae are a family of halophilic Proteobacteria. ==History== The family was originally described in 1988 to contain the genera ''Halomonas'' and ''Deleya''.〔FRANZMANN (P.D.), WEHMEYER (U.) and STACKEBRANDT (E.): Halomonadaceae fam. nov., a new family of the class Proteobacteria to accommodate the genera Halomonas and Deleya. ''Syst. Appl. Microbiol.'', 1988, 11, 16-19.〕 In 1989, ''Chromobacterium marismortui'' was reclassified as ''Chromohalobacter marismortui'' forming a third genus in the family Halomonadaceae.〔VENTOSA (A.), GUTIERREZ (M.C.), GARCIA (M.T.) and RUIZ-BERRAQUERO (F.): Classification of "Chromobacterium marismortui" in a new genus, Chromohalobacter gen. nov., as Chromohalobacter marismortui comb. nov., nom. rev. ''Int. J. Syst. Bacteriol.'', 1989, 39, 382-386.〕 Subsequently, in 1990 a species was discovered and was originally proposed to be called ''Volcaniella eurihalina'' forming a new genus in the ''Halomonadaceae'',〔QUESADA (E.), VALDERRAMA (M.J.), BEJAR (V.), VENTOSA (A.), GUTIERREZ (M.C.), RUIZ-BERRAQUERO (F.) and RAMOS-CORMENZANA (A.): Volcaniella eurihalina gen. nov., sp. nov., a moderately halophilic nonmotile gram-negative rod. ''Int. J. Syst. Bacteriol.'', 1990, 40, 261-267〕 but was later (in 1995) reclassified as a member of the genus ''Halomonas''.〔Mellado, E., Moore, E. R. B., Nieto, J. J. & Ventosa, A. (1995). Phylogenetic inferences and taxonomic consequences of 16S. ribosomal DNA sequence comparison of Chromohalobacter marismortui, Volcaniella eurihalina, and Deleya salina and reclassification of V. eurihalina as Halomonas eurihalina comb. nov. ''Int J Syst Bacteriol'' 45, 712–716.〕 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.〔D. R. Arahal, W. Ludwig, K. H. Schleifer and A. Ventosa Phylogeny of the family Halomonadaceae based on 23S and 16S rDNA sequence analyses. ''International Journal of Systematic and Evolutionary Microbiology'', Vol 52, 241-249〕 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.〔DOBSON (S.J.) and FRANZMANN (P.D.): Unification of the genera ''Deleya'' (Baumann et al. 1983), ''Halomonas'' (Vreeland et al. 1980), and ''Halovibrio'' (Fendrich 1988) and the species ''Paracoccus halodenitrificans'' (Robinson and Gibbons 1952) into a single genus, ''Halomonas'', and placement of the genus ''Zymobacter'' in the family Halomonadaceae. Int. J. Syst. Bacteriol., 1996, 46, 550-558〕 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'',〔ARAHAL (D.R.), CASTILLO (A.M.), LUDWIG (W.), SCHLEIFER (K.H.) and VENTOSA (A.): Proposal of Cobetia marina gen. nov., comb. nov., within the family Halomonadaceae, to include the species Halomonas marina. ''Syst. Appl. Microbiol.'', 2002, 25, 207-211.〕 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.〔ANAN'INA (L.N.), PLOTNIKOVA (E.G.), GAVRISH (E.Y.), DEMAKOV (V.A.) and EVTUSHENKO (L.I.): Salinicola socius gen. nov., sp. nov., a moderately halophilic bacterium from a naphthalene-utilizing microbial association. ''Microbiology'', 2007, 76, 324-330 (translation of ''Mikrobiologiya'', 2007, 76, 369-376).〕 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 "Candidatus Portiera aleyrodidarum" (primary endosymbionts of whiteflies). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Halomonadaceae」の詳細全文を読む スポンサード リンク
