Article Synopsis
  • Two new species of actinobacteria, AO-9 and AO-18, were isolated from paddy soil in Daejeon, South Korea, characterized as Gram-positive, motile, and non-spore-forming.
  • Through phylogenetic analysis using 16S rRNA gene sequences, these strains displayed high sequence similarity to known species but were determined to be novel based on DNA-DNA hybridization and average nucleotide identity.
  • Key features include their specific fatty acid composition, predominant quinone MK-9 (H), and a DNA G+C content of 72.9 mol%, leading to the proposal of the new species name.
