Spirosoma flavus sp. nov., a novel bacterium from soil of Jeju Island

A novel, Gram-staining negative, yellow pigmented bacterial strain, designated 15J11-2 T , was isolated from soil sample on Jeju Island, Republic of Korea. The strain was subjected to a taxonomic study using a polyphasic approach. The strain was able to grow at temperature range from 10°C to 30°C, p...

Description
Summary:A novel, Gram-staining negative, yellow pigmented bacterial strain, designated 15J11-2 T , was isolated from soil sample on Jeju Island, Republic of Korea. The strain was subjected to a taxonomic study using a polyphasic approach. The strain was able to grow at temperature range from 10°C to 30°C, pH 7–8, and in presence of 0–1% (w/v) NaCl. Comparative 16S rRNA gene sequence analysis showed that strain 15J11-2 T belongs to the genus Spirosoma and levels of 16S rRNA gene sequence similarity ranged from 91.5% to 89.8%. The genomic DNA G + C content of strain 15J11-2 T was 46.0 mol%. The isolate contained phosphatidylethanolamine and an unidentified aminophospholipid as the main polar lipids, menaquinone MK-7 as the predominant respiratory quinone, and summed feature 3 (C 16:1 ω 6 c /C 16:1 ω 7 c ; 39.4%), C 16:1 ω 5 c (27.1%), and C 16:0 (13.0%) as the major fatty acids, which supported the affiliation of strain 15J11-2 T to the genus Spirosoma . The results of physiological and biochemical tests allowed genotypic and phenotypic differentiation of strain 15J11-2 T from recognized Spirosoma species. On the basis of its phenotypic properties, genotypic distinctiveness, chemotaxonomic features, strain 15J11-2 T represents a novel species of the genus Spirosoma , for which the name Spirosoma flavus sp. nov. is proposed. The type strain is 15J11-2 T (= KCTC 52026 T = JCM 31998 T ).
