Abstract
- Two extremely halophilic strains, designated SYSU A558-1<superscript>T</superscript> and SYSU A121-1, were isolated from a saline sediment sample collected from Aiding salt-lake, China. Cells of strains SYSU A558-1<superscript>T</superscript> and SYSU A121-1 were Gram-stain-negative, coccoid, and non-motile. The strains were aerobic and grew at NaCl concentration of 10–30% (optimum, 20–22%), at 20–55 °C (optimum, 37–42 °C) and at pH 6.5–8.5 (optimum, 7.0–8.0). Cells lysed in distilled water. The polar lipids were phosphatidyl choline, phosphatidylglycerol phosphate methyl ester, disulfated diglycosyl diether-1 and unidentified glycolipid. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the two strains SYSU A558-1<superscript>T</superscript> and SYSU A121-1 were closely related to the membranes of the genus Haloterrigena. Phylogenetic and phylogenomic trees of strains SYSU A558-1<superscript>T</superscript> and SYSU A121-1 demonstrated a robust clade with Haloterrigena turkmenica, Haloterrigena salifodinae and Haloterrigena salina. The genomic DNA G + C content of strains SYSU A558-1<superscript>T</superscript> and SYSU A121-1 were 65.8 and 65.0%, respectively. Phenotypic, phylogenetic, chemotaxonomic and genome analysis suggested that the two strains SYSU A558-1<superscript>T</superscript> and SYSU A121-1 represent a novel species of the genus Haloterrigena, for which the name Haloterrigena gelatinilytica sp. nov. is proposed. The type strain is SYSU A558-1<superscript>T</superscript> (= KCTC 4259<superscript>T</superscript> = CGMCC 1.15953<superscript>T</superscript>). [ABSTRACT FROM AUTHOR]
