Geoalkalibacteraceae

Abstract

Ge.o.al.ka.li.bac.te.ra.ce'ae. N.L. masc. n. Geoalkalibacter , type genus of the family; L. fem. pl. n. suff. ‐ aceae , ending to denote a family; N.L. fem. pl. n. Geoalkalibacteraceae , the family of the genus Geoalkalibacter . Desulfobacterota_F / Desulfuromonadia / Desulfuromonadales / Geoalkalibacteraceae The family is a member of the order Desulfuromonadales in the phylum Desulfobacterota_F and consists of a single genus Geoalkalibacter . The family Geoalkalibacteraceae includes strictly anaerobic chemolitho‐ or chemoorganotrophic bacteria that inhabit soda lakes or petroleum reservoirs. They are alkalitolerant or alkaliphiles, halotolerant or moderate halophiles using molecular hydrogen or a wide range of organic compounds as energy sources and either soluble or insoluble Fe(III), Mn(IV), or sulfur compounds as electron acceptors. Members of this family are electroactive microorganisms and can also use Fe(II)‐containing minerals or cathodes as electron donors. DNA G + C content (mol%) : 57.05–60.57 (genome analysis). Type genus : Geoalkalibacter Zavarzina et al. 2006, VL115 emend. Greene et al. 2009.
