The genome size is 4.86 Mbp, G+C percentage is 54.88%, with 99.89% completeness and 0.12% contamination. It contains two plasmids (4,416 bp; 2,494 bp). Strain CLA-AC-H004 was determined to be a strain of Enterobacter quasihormaechei (99.8%) based on 16S rRNA gene analysis. Separation from existing Enterobacter species was confirmed by ANI comparison, which gave a value of 93.69% to E. quasihormaechei. GTDB-Tk classification of strain CLA-AC-H004 as ‘Enterobacter hormaechei_A’ supports the proposal of a novel species. An ANI value of 99.01% was obtained when compared to Enterobacter hormaechei subsp. hoffmannii. However, given the separation from E. hormaechei we propose it these strains represent a separate species and not only a sub-species. ANI comparison also highlighted similarity with Pedobacter himalayensis (95.89%), which has been classified as ‘Enterobacter hormaechei_B’ within GTDB. However, this suggests reclassification of Pedobacter may be required in future. Functional analysis showed the strain has 497 transporters, 98 secretion genes, and predicted utilization of arbutin, salicin, cellobiose, sucrose, and starch along with production of L-glutamate, biotin, riboflavin, acetate, propionate, and folate. In total, 316 CAZymes were identified, with 37 different glycoside hydrolase families and 19 glycoside transferase families represented. The strain CLA-AC-H004 (phylum Pseudomonadota, family Enterobacteriaceae) was isolated from human faeces.
