The cells were Gram-negative-staining and motile. The strain grew at 15–50 °C, 10–30 % (w/v) NaCl and pH 6.0–8.0. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain D43T is affiliated with the family Halobacteriaceae in the domain Archaea and had 95.5 % 16S rRNA gene sequence similarity with Haladaptatus paucihalophilus DX253T. The sequence from strain D43T formed a clade with those from Hap. paucihalophilus regardless of which tree-generating algorithm was used. DNA–DNA hybridization experiments showed 25.8 % relatedness between the isolate and Hap. paucihalophilus KCTC 4006T. Major lipids were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester and two unidentified glycolipids. The DNA G+C content of the isolate was 56.5 mol%. On the basis of this polyphasic taxonomic study, strain D43T represents a novel species in the genus Haladaptatus, for which the name Haladaptatus cibarius sp. nov. is proposed. The type strain is D43T (=DSM 19505T =JCM 15962T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.013037-0
