AI Article Synopsis
- Strain I54 is a newly identified, rod-shaped, non-motile bacterium found in a freshwater river in Iksan, South Korea, classified in the genus Soonwooa of the Flavobacteriaceae family.
- Genetic analysis revealed a 97.5% similarity to Soonwooa buanensis, indicating its close relation to this known species.
- The strain's unique fatty acid profile and polar lipids, along with a specific genomic composition, led to the proposal of a new species name, Soonwooapurpurea sp. nov., with the type strain designated as I54.
Article Abstract
A pale-brown-coloured, rod-shaped, non-motile, and Gram-reaction-negative bacterium, strain I54, was isolated from a water sample of a freshwater river in Iksan, Republic of Korea. The phylogenetic affiliation based on 16S rRNA gene sequence analysis showed that strain I54 belonged to the genus Soonwooa of the family Flavobacteriaceae with a sequence similarity of 97.5 % to Soonwooa buanensis HM0024. The major fatty acids (>5 %) of strain I54 were iso-C15 : 0, anteiso-C15 : 0, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) and iso-C17 : 0 3-OH. Phosphatidylethanolamine, one aminolipid and two unknown lipids were the major polar lipids. The G+C content of the genomic DNA was 34.2 (±0.3)mol% and MK6 was the sole respiratory quinone. On the basis of its molecular and phenotypic characteristics, strain I54 represents a novel species in the genus Soonwooa, for which the name Soonwooapurpurea sp. nov. is proposed. The type strain is I54 (=KCTC 52722=JCM 31880).
