Report on 30 unrecorded bacterial species of the phylum Firmicutes isolated from Korea in 2016

During the course of investigation of indigenous prokaryotic species in Korea, a total of 30 bacterial strains belonging to the phylum Firmicutes were isolated from diverse environmental sites such as soil, avian feces, wastewater treatment plants, fermented vegetables, seawater, algae, sea cucumber, octopus and tidal flat sediment. Phylogenetic analysis based on 16S rRNA gene sequences revealed that each strain showed high sequence similarity (${\geq}98.7%$) to the closest type strain and formed a robust phylogenetic clade with the most closely related species in the phylum Firmicutes. To date, there is no official record of these 30 species in Korea. Therefore, we report 26 species of 12 genera in the order Bacillales and 4 species of 4 genera in the order Lactobacillales which have not been reported in Korea. Morphological and biochemical characteristics, isolation sources and NIBR deposit numbers are described in the species descriptions.
