A report of 34 unrecorded bacterial species in Korea , belonging to the Actinobacteria

The recently proposed phylum Actinobacteria (Ludwig et al., 2012) is composed of aerobic, Gram-staining-positive bacteria that have high-G + C contents in their genomic DNAs. They exhibit a very wide range of morphology and form cocci, rods or fragmented or branched hyphae depending on species. Some of them produce resting structure such as spores and sporangium on permanent, well-developed mycelium (Goodfellow and Cross, 1984; Ensign, 1992). The phylum Actinobacteria is well supported by analyses of the 16S and 23S rRNA, presence of conserved insertions and deletions in certain proteins, and characteristic gene rearrangements (Goodfellow and Fiedler, 2010) and encompasses six classes Actinobacteria, Acidimicrobiia , Coriobacteriia , Nitriliruptoria , Rubrobacteria and Thermoleophilia (Ludwig et al., 2012). The class Actinobacteria is composed of 15 orders Actinomycetales, Actinopolysporales, Bifidobacteriales, Catenulisporales, Corynebacteriales, Frankiales, Glycomycetales , Jiangellales , Kineosporiales , Micromonosporales, Micrococcales, Propionibacteriales, Pseudonocardiales, Streptomycetales and Streptosporangiales. Members of this class have been received considerable Journal of Species Research 6(1):1-14, 2017
