Abstract:
Strain YSM-123 T was isolated from commercial salt made from Japanese seawater in Niigata prefecture. Optimal NaCl and Mg 2+ concentrations for growth were 4.0–4.5 M and 5 mM, respectively. The isolate was a mesophilic and slightly alkaliphilic haloarchaeon, whose optimal growth temperature and pH were 37 °C and pH 8.0–9.0. Phylogenetic analysis based on 16S rRNA gene sequence analysis suggested that strain YSM-123 T is a member of the phylogenetic group defined by the family Halobacteriaceae , but there were low similarities to type strains of other genera of this family (≤90 %); for example, Halococcus (similarity 〈 89 %), Halostagnicola ( 〈 89 %), Natronolimnobius ( 〈 89 %), Halobiforma ( 〈 90 %), Haloterrigena ( 〈 90 %), Halovivax ( 〈 90 %), Natrialba ( 〈 90 %), Natronobacterium ( 〈 90 %) and Natronococcus ( 〈 90 %). The G+C content of the DNA was 63 mol%. Polar lipid analysis revealed the presence of phosphatidylglycerol, phosphatidylglycerophosphate methyl ester, disulfated diglycosyl diether and an unknown glycolipid. On the basis of the data presented, we propose that strain YSM-123 T should be placed in a new genus and species, Natronoarchaeum mannanilyticum gen. nov., sp. nov. The type strain of Natronoarchaeum mannanilyticum is strain YSM-123 T (=JCM 16328 T =CECT 7565 T ).
