Abstract
A novel Gram-stain-negative, rod-shaped, yellow bacterium, designated as LB1R16T, was isolated from the Laigu glacier on the Tibetan Plateau, PR China. Strain LB1R16T was catalase-positive, oxidase-negative and grew at 0–28 °C, pH 6.0–8.0 and in the absence of NaCl. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain LB1R16T belongs to the family
Sphingosinicellaceae
but formed an independent lineage. The highest level of 16S rRNA gene sequence similarities were found to
Polymorphobacter arshaanensis
DJ1R-1T (95.24 %),
Sphingoaurantiacus capsulatus
YLT33T (94.78 %) and
Sandarakinorhabdus limnophila
DSM 17366T (94.67 %). The genomic DNA G+C content was 68.8 mol%. The main cellular fatty acids were summed feature 8 (C18 : 1
ω7c/C18 : 1
ω6c), summed feature 3 (C16 : 1
ω7c/C16 : 1
ω6c), C16 : 0 and C12 : 0-OH. The respiratory quinone was ubiquinone-10. The polar lipids were phosphatidylethanolamine, phosphatidylglycerol, one sphingoglycolipid, one unidentified aminolipid, one unidentified phospholipid and two unidentified polar lipids, which were different from the type strains of
Polymorphobacter arshaanensis
,
Sphingoaurantiacus capsulatus
and
Sandarakinorhabdus limnophila
. Based on a polyphasic approach, a novel species of a new genus, Glacieibacterium frigidum gen. nov., sp. nov., within the family
Sphingosinicellaceae
is proposed. The type strain is LB1R16T (=CGMCC 1.11941T=NBRC 113873T).
