The genome of Digestoria delfossei in OTU_1 is complete and closed, 2.3 Mbp long, with a GC content of 54.3%, and it contains two rRNA operons. The species represents a distinct lineage defined by ANI ≥ 95% to its known relatives. Therefore, only the novel genus and species are formally established, while all higher‑level ranks remain unnamed pending further phylogenomic resolution of the phylum. D. delfossei encodes a complete glycolysis pathway with exception for pyruvate kinase, previously shown to be replaced by pyruvate orthophosphate dikinase in Cloacimonadota genomes, and the microorganism can oxidize pyruvate further to acetyl-CoA and acetate. It is capable of beta-oxidation and protein degradation (i.e., encoding multiple peptidases) with a complete metabolism of histidine to glutamate.
