The genome size is 3.17 Mbp, G+C percentage is 45.01%, with 99.37% completeness and 0.27% contamination, including a single plasmid of 7,983 bp. The closest relative to strain CLA-AA-H78B was Hominiventricola filiformis (96.24%) based on 16S rRNA gene analysis. POCP analysis confirmed genus assignment to Hominiventricola, with a POCP value of 69.06% to the type strain of the only current species within this genus, H. filiformis. GTDB-Tk classified strain CLA-AA-H78B as ‘Choladocola sp003480725’ within “Candidatus Choladocola”. The latter is a heterosynonym of Hominiventricola, a validly published name. ANI comparison confirmed that strain CLA-AA-H78B represents a novel species as the ANI value to H. filiformis was 82.98%. Functional analysis showed the strain has 134 transporters, 31 secretion genes, and predicted utilization of cellobiose, starch, arbutin, salicin, and production of L-glutamate, folate, acetate, propionate, and cobalamin. In total, 134 CAZymes were identified. The strain CLA-AA-H78B (phylum Bacillota, family Lachnospiraceae) was isolated from human faeces.
