Abstract

To obtain unrecorded bacterial species in Korea, various soils of coastal areas were collected from the Republic of Korea in 2022. After plating the samples on marine agar and incubating aerobically and anaerobically, approximately 1,700 bacterial strains were isolated and identified using 16S rRNA gene sequences. A total of 20 strains showed ≥98.7% 16S rRNA gene sequence similarity with validly published bacterial species but not reported in Korea, indicating they are unrecorded bacterial species in Korea. The unrecorded bacterial strains belonged to four phyla, six classes, 15 orders, 16 families, and 19 genera which were assigned to Blastomonas and Sphingomonas of the class Alphaproteobacteria; Pseudidiomarina, Kushneria, Salinicola, and Salinisphaera of the class Gammaproteobacteria; Evansella, Virgibacillus, and Paenibacillus of the class Bacilli; Cyclobacterium of the class Cytophagia; Pedobacter of the class Sphingobacteriia; and Demequina, Ornithinimicrobium, Blastococcus, Jatrophihabitans, Kineococcus, Glaciihabitans, Aeromicrobium and Streptomyces of the class Actinomycetes. The details of the 20 unreported species, including Gram reaction, morphology, biochemical characteristics, and phylogenetic position are also provided in the description of the strains.
