According to Spring et al. (2005), this species is an earlier heterotypic synonym of Methanogeniumfrittonii Harris et al. 1996.Publication:
Spring S, Schumann P, Sproer C. Methanogenium frittonii Harris et al. 1996 is a later synonym of Methanoculleus thermophilus (Rivard and Smith 1982) Maestrojuan et al. 1990. Int J Syst Evol Microbiol 2005; 55:1097-1099.
The specific epithet thermophilicum (sic) has been corrected in the new combination Methanoculleus thermophilus [see, Methanoculleus thermophilus corrig. (Rivard and Smith 1982) Maestrojuán et al. 1990, comb. nov.]. However the name "Methanogenium thermophilum" corrig. has never been formally proposed before December 14, 2000 (date of publication of the amended Rule 61; see Int. J. Syst. Evol. Microbiol., 2000, 50, page 2239, column 2). Consequently, in the "List of Prokaryotic names with Standing in Nomenclature", the epithet thermophilicum (sic) has been maintained for Methanogenium thermophilicum.
