原始语种摘要: Abstract(#br)A novel actinobacterium, strain DB165 T , was isolated from cold waters of Llullaillaco Volcano Lake (6170 m asl) in Chile. Phylogenetic analysis based on 16S rRNA gene sequences identified strain DB165 T as belonging to the genus Subtercola in the family Microbacteriaceae , sharing 97.4% of sequence similarity with Subtercola frigoramans DSM 13057 T , 96.7% with Subtercola lobariae DSM 103962 T , and 96.1% with Subtercola boreus DSM 13056 T . The cells were observed to be Gram-positive, form rods with irregular morphology, and to grow best at 10–15 °C, pH 7 and in the absence of NaCl. The cross-linkage between the amino acids in its peptidoglycan is type B2γ; 2,4-diaminobutyric acid is the diagnostic diamino acid; the major respiratory quinones are MK-9 and MK-10; and the...
