A motile, rod-shaped, pink-pigmented, extremely halophilic archaeon, strain SF3-213T, was isolated from a crystallizer pond at the Cargill Solar Salt Plant, Newark, California (USA). Analysis of the almost-complete 16S rRNA gene sequence showed that the isolate was phylogenetically related to species of the genus Halorubrum, with a close relationship to Halorubrum trapanicum NRC 34021T (98.6 % similarity), Halorubrum sodomense ATCC 33755T (98.3 %) and Halorubrum xinjiangense AS 1.3527T (98.2 %). The polar lipids of strain SF3-213T were C20C20 derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate and a sulfated diglycosyl-diether. Strain SF3-213T grew in 2.5–5.0 M NaCl. The temperature and pH ranges for growth were 25–42 °C and 6.8–8.5, respectively. Optimal growth occurred at 3.5–4.5 M NaCl, 37 °C and pH 7.3. Mg2+ was required for growth. The DNA G+C content was 69.4 mol%. DNA–DNA hybridization values lower than 70 % were obtained between strain SF3-213T and the closely related species of the genus Halorubrum. Based on the data presented in this study, strain SF3-213T represents a novel species for which the name Halorubrum californiense sp. nov. is proposed; the type strain is SF3-213T (=CECT 7256T=DSM 19288T=JCM 14715T).

Abbreviations: PG, phosphatidylglycerol; PGP-Me, phosphatidylglycerol phosphate methyl ester; PGS, phosphatidylglycerol sulfate; S-DGD, sulfated diglycosyl-diether

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain SF3-213T is EF139654.
