Reclassification of the Clostridium clostridioforme and Clostridium sphenoides clades as Enterocloster gen. nov. and Lacrimispora gen. nov., including reclassification of 15 taxa

Key Points

• This research aims to reassess the taxonomy of specific clostridial clades, leading to their reclassification under new genera.
• Reassessment of molecular and morphological data for clostridioforme and sphenoides clades.
• Comparison with existing microbial classifications.
• Formal proposal for the establishment of new genera.
• Fifteen taxa were reclassified under the genera Enterocloster and Lacrimispora as a result of this study.
• New genera reflect significant phylogenetic relationships among the clades identified.
• Implications for understanding microbial diversity and taxonomy in the Clostridia family.
