Abstract

In 2021, a total of 27 bacterial strains were isolated from soil, tree bark, moss, wetland, sea sediment, tidal flat, seawater and seaweed within Republic of Korea. Based on the analysis of 16S rRNA gene sequence (>98.7% sequence similarity), these isolates were assigned to the class Alphaproteobacteria as unrecorded species in Korea. The 27 strains were classified into the 10 families: Maricaulaceae of the order Caulobacterales; Brucellaceae, Methylobacteriaceae, Nitrobacteraceae and Rhizobiaceae of the order Hyphomicrobiales; Micropepsaceae of the order Micropepsales; Rhodobacteraceae of the order Rhodobacterales; Azospirillaceae of the order Rhodospirillales; and Erythrobacteraceae and Sphingomonadales of the order Sphingomonadaceae. There is no official report of these 27 species in Korea. Therefore, we report 27 isolates as unrecorded species, and described isolation sources, Gram-stain reactions, physiological and biochemical properties and morphologies of these strains.
