| Abstract |
Three halophilic archaeal strains, MH1-34-1(T), MH1-16-1 and MH1-224-5 were isolated from commercial salt samples produced from seawater in Indonesia, the Philippines and Japan, respectively. Cells of the three strains were pleomorphic and stained Gram-negative. Strain MH1-34-1(T) was orange-red pigmented, while MH1-16-1 and MH1-224-5 were pink-pigmented. Strain MH1-34-1(T) was able to grow at 12-30 % (w/v) NaCl (with optimum at 18 % NaCl, w/v) at pH 4.5-7.2 (optimum, pH 5.2-5.5) and at 15-45 °C (optimum, 42 °C). Strains MH1-16-1 and MH1-224-5 grew in slightly different ranges. These strains required at least 1 mM Mg(2+) for growth. The 16S rRNA gene sequences of strains MH1-34-1(T), MH1-16-1 and MH1-224-5 were almost identical (99.8-99.9 % similarities), and the closest relative was Halarchaeum acidiphilum MH-1-52-1(T) with 98.4 % similarities. The DNA G+C contents of MH1-34-1(T), MH1-16-1 and MH1-224-5 were 59.3, 60.8 and 61.0 mol%, respectively. The level of DNA-DNA relatedness amongst the three strains was 90-91 %, while that between each of the three strains and Halarchaeum acidiphilum MH1-52-1(T) was 51-55 %. Based on the phenotypic, genotypic and phylogenetic analyses, it is proposed that the isolates should represent a novel species of the genus Halarchaeum, for which the name Halarchaeum salinum sp. nov. is proposed. The type strain is MH1-34-1(T) ( = JCM 16330(T) = CECT 7574(T)). |
