Spirosoma humi sp. nov., Isolated from Soil in South Korea
A Gram-stain-negative, non-motile, rod-shaped, aerobic bacterial strain, designated S7-4-1 T , was isolated from soil in Gyeongsangnam-do, South Korea and characterized using a polyphasic approach to determine its taxonomic position. Phylogenic analysis based on the 16S rRNA gene sequence showed tha...

Summary: | A Gram-stain-negative, non-motile, rod-shaped, aerobic bacterial strain, designated S7-4-1
T
, was isolated from soil in Gyeongsangnam-do, South Korea and characterized using a polyphasic approach to determine its taxonomic position. Phylogenic analysis based on the 16S rRNA gene sequence showed that strain S7-4-1
T
belonged to the family
Cytophagaceae
and was most closely related to
Spirosoma fluviale

iso (9.3%) as the major fatty acids, menaquinone MK-7 as the predominant respiratory quinone, and phosphatidylethanolamine and an unidentified aminophospholipid as the main polar lipids, which supported its affiliation with the genus
Spirosoma
. The results of physiological and biochemical tests allowed the genotypic and phenotypic differentiation of the isolate from recognized
Spirosoma
species. On the basis of its phenotypic properties, genotypic distinctiveness, and chemotaxonomic features, strain S7-4-1
T
represents a novel species of the genus
Spirosoma
, for which the name
Spirosoma humi
sp. nov. is proposed. The type strain is S7-4-1
