The isolate was able to grow within a pH range of 5.0–9.0 and a temperature range of 5–35 °C and it tolerated up to 2 % (w/v) NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid as diagnostic diamino acid. The predominant isoprenoid quinone was MK-8(H4). The major polar lipids were phosphatidylinositol, phosphatidylethanolamine and diphosphatidylglycerol; phosphatidylglycerol and several unknown phospholipids were also detected. Mycolic acids were absent. The only whole-cell sugar was glucose. The major cellular fatty acids were iso-C16 : 0, C17 : 1 ω8c and iso-C15 : 0. 16S rRNA gene sequence analysis indicated that strain 5317S-21T was related phylogenetically to members of the genus Knoellia, with 97.4 % sequence similarity to the type strains of Knoellia sinensis and Knoellia subterranea. The G+C content of the genomic DNA of strain 5317S-21T was 73 mol%. Levels of DNA–DNA relatedness between strain 5317S-21T and the type strains of Knoellia sinensis and Knoellia subterranea were 37 and 41 %, respectively. It was concluded that strain 5317S-21T represents a novel species of the genus Knoellia, for which the name Knoellia aerolata sp. nov. is proposed. The type strain is 5317S-21T (=KACC 20583T =DSM 18566T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65293-0
