• Notes:
  • Gibbons and Murray (1978) assigned this class to the phylum "Gracilicutes" Gibbons and Murray 1978 (Approved Lists 1980). Publication: Gibbons NE, Murray RGE. Proposals Concerning the Higher Taxa of Bacteria. International Journal of Systematic Bacteriology 1978; 28:1-6.
  • Gibbons and Murray (1978) assigned the subclass Anoxyphotobacteriae Gibbons and Murray 1978 (Approved Lists 1980) to this class. Publication: Gibbons NE, Murray RGE. Proposals Concerning the Higher Taxa of Bacteria. International Journal of Systematic Bacteriology 1978; 28:1-6.
  • Gibbons and Murray (1978) assigned the subclass "Oxyphotobacteriae" Gibbons and Murray 1978 to this class. Publication: Gibbons NE, Murray RGE. Proposals Concerning the Higher Taxa of Bacteria. International Journal of Systematic Bacteriology 1978; 28:1-6.
  • This taxon name is occasionally misprinted in some sources as: "Pholobacteria".
  • Illegitimate according to Tindall (2014). Tindall (2014) notes that the type order Rhodospirillales Pfennig and Trüper 1971 was provided in Gibbons and Murray (1978) but that this order was not included in the Approved Lists. This is inaccurate, as the order is found in Skerman et al. (1980). However, Gibbons and Murray (1978) actually indicated Oxyphotobacteriae as type subclass of Photobacteria and Rhodospirillales as type order of Oxyphotobacteriae. But in contrast to Anoxyphotobacteriae Gibbons and Murray 1978, Oxyphotobacteriae was not included in the Approved Lists. Tindall (2014): "Not currently used as a class name; as applied by Gibbons and Murray (1978) the name encompasses those Gram-negative (i.e. Gram-stain-negative) prokaryotes that are capable of growing by oxygenic or anoxygenic photosynthesis.".
