Notes:
- 🧕 Kämpfer et al. (2013) assigned this genus to the family Rhodobacteraceae Garrity et al. 2006. Publication: Kampfer P, Arun AB, Rekha PD, Busse HJ, Young CC, Glaeser SP. Ruegeria intermedia sp. nov., a moderately thermophilic bacterium isolated from a coastal hot spring. Int J Syst Evol Microbiol 2013; 63:2538-2544. 🇩🇪
- 🚂 For the type species of this genus another name is in use, which is affiliated with the genus Ruegeria Uchino et al. 1999. Publication: Yi H, Lim YW, Chun J. Taxonomic evaluation of the genera Ruegeria and Silicibacter: a proposal to transfer the genus Silicibacter Petursdottir and Kristjansson 1999 to the genus Ruegeria Uchino et al. 1999. Int J Syst Evol Microbiol 2007; 57:815-819. 🇰🇷
- 🙄 This taxon name is occasionally misprinted (or affected by an OCR error) in some sources as: "Sificibacter"; "Silicobacter". — 🤨 This taxon name is occasionally used in plural form as: "Silicibacteria".
- ❗ Silicibacter is the correct name instead if this genus is regarded as a separate genus (i.e., if its nomenclatural type is not assigned to another genus whose name is validly published, legitimate and not rejected and has priority).
- 🎰 The BRCs most frequently used for deposits in this group are: DSM: 2; ATCC: 1; KCTC: 1.
- 🧍 According to Muramatsu et al. 2007, 16S rRNA gene sequence analysis suggests that the genera Ruegeria and Silicibacter are closely related and should be integrated into one genus (i.e. Ruegeria Uchino et al. 1999 which has priority over Silicibacter Petursdottir and Kristjansson 1999). However, their differential phenotypic properties do not support this unification. Consequently the authors retain the two species of Silicibacter in their paper.
