We propose to name PEL1, the most complete and persistent genomospecies of clade IIIb in the freshwater ecosystems sample, as
Allofontibacter lacus sp. nov. [formerly "
Candidatus Fonsibacter lacus"]. In addition to the previously described properties of the genus
Allonsibacter corrig. Henson, et al (2018), the proposed species is described as follows. Small, curved rod cells of approximately 1 × 0.2 μm. Partial genome sequence WB8_6_001 with estimated completeness of 77.5% and contamination of 0.9% is 1.08 Mbp in size, with 1375 predicted genes, a coding density of 92.0%, and a G + C content of 35.9%. WB8_6_001 has an ANI of 84.9% and AAI of 87.0% with the
Allofontibacter communis corrig. Henson et al (2018) [formerly "
Ca. Fonsibacter ubiquis"] str. LSUCC0530T genome, the only currently described member of the
Allofontibacter genus. The type material for this species is the genome WB8_6_001, identified in the freshwater lakes along the Chattahoochee River, Southeast USA. The representative genome is available in GenBank under accession number
SAMN10223538.
