Completion and contamination were estimated using CheckM2. RNAs were detected with the Prokaryotic Genome Annotation Pipeline (PGAP). The 16S rRNA gene includes a large (586 bp) intervening sequence (shown in Genbank accession PP060619.1). Completion of the 23S rRNA gene was estimated using the Aeropyrum pernix 23S rRNA gene (NR_103216.2).
