RT Journal Article SR Electronic(1) A1 Jongrungruangchok, Suchada A1 Tanasupawat, Somboon A1 Kudo, TakujiYR 2008 T1 Micromonospora chaiyaphumensis sp. nov., isolated from Thai soils JF International Journal of Systematic and Evolutionary Microbiology, VO 58 IS 4 SP 924 OP 928 DO https://doi.org/10.1099/ijs.0.65594-0 PB Microbiology Society, SN 1466-5034, AB Three actinomycete strains, MC5-1T, MC7-1 and R1-1, were isolated from soil samples collected in Thailand. Their taxonomic positions were determined using a polyphasic approach. The chemotaxonomic characteristics of these strains coincided with those of the genus Micromonospora, i.e. meso-diaminopimelic acid and N-glycolyl muramic acid were present in the cell-wall peptidoglycan, the whole-cell sugars were of pattern D, the phospholipids were of type II and the cellular fatty acids were of type 3b. Phylogenetic analysis of the 16S rRNA gene sequences revealed a close relationship between strains MC5-1T, MC7-1 and R1-1 (99.8 % sequence similarity) and Micromonospora auratinigra JCM 12357T (99.3 %). The three novel strains were clearly distinguishable from M. auratinigra JCM 12357T from the low DNA–DNA relatedness (≤43.4 %). On the basis of the data presented, strain MC5-1T represents a novel species of the genus Micromonospora, for which the name Micromonospora chaiyaphumensis is proposed. The type strain is MC5-1T (=KCTC 19332T=JCM 12873T=PCU 267T=TISTR 1564T)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.65594-0
