The Families Conexibacteraceae, Patulibacteraceae and Solirubrobacteraceae

Abstract

Three families will be here discussed, Conexibacteraceae, Patulibacteraceae, and Solirubrobacteraceae, which are members of the order Solirubrobacterales together in this chapter. Members of this order are Gram-positive, mesophilic, and the peptidoglycan contains meso-diaminopimelic acid (meso-Dpm) as diagnostic diamino acid. The pattern of 16S rRNA signatures consist of nucleotides at positions 63 : 104 (G-C), 70 : 98 (G-C), 370 : 391 (C-G), 580 : 776 (U-A), 657 : 749 (U-A), 670 : 736 (A-U), 681 : 709 (U-A), 941 : 1342 (A-U), 953 : 1228 (G-C), 954 : 1226 (G-C), 1051 : 1207 (G-C), 1118 : 1155 (U-A) and 1311 : 1326 (A-U). The three families of the order Solirubrobacterales are monogeneric: The family Conexibacteraceae contains two species, Conexibacter woesei and C. arvalis (Monciardini et al., Int J Syst Evol Microbiol 53:569–576, 2003; Seki et al., Int J Syst Evol Microbiol 53:2400–2404, 2012); the family Patulibacteraceae contains three species, Pautulibacter minatonensis, P. americanus, and P. ginsengiterrae (Kim et al., Int J Syst Evol Microbiol 62:563–568, 2012; Takahashi et al., Int J Syst Evol Microbiol 56:401–406, 2006; Reddy et al., Int J Syst Evol Microbiol 59:87–94, 2009) and the family Solirubrobacteraceae comprises three species, Solirubrobacter pauli, S. soli and S. ginsenosidimutans (An et al., Int J Syst Bacteriol 61:2606–2609, 2011; Kim et al., Int J Syst Evol Microbiol 57:1453–1455, 2007; Singleton et al., Int J Syst Evol Microbiol 53:485–490, 2003). These organisms are phylogenetic neighbors of the families Gaiellaceae, Rubrobacteraceae, and Thermoleophilaceae (Albuquerque et al., Syst Appl Microbiol 34:595–599, 2011; Reddy and Garcia-Pichel, Int J Syst Evol Microbiol 59:87–94, 2009).
