  • 🧍 Methanomassiliicoccus Dridi et al. 2012 and Methanomassiliicoccus luminyensis Dridi et al. 2012, appear in the August 2012 issue of the IJSEM. However, these names were not validly published because the DSMZ accession number (DSM 24529), cited in the paper by Dridi et al. 2012, is a patent deposit [see Rule 30 (4).]. In order to validly publish these names, Methanomassiliicoccus Dridi et al. 2012 and Methanomassiliicoccus luminyensis Dridi et al. 2012, are cited on Validation List 148. Publication: Euzeby JP.
