Abstract
A novel actinomycete, strain P0402T, was isolated from peat swamp forest soil collected in Thailand. Its taxonomic position was determined by using a polyphasic taxonomic approach. The chemotaxonomic characteristics of this strain matched those of the genus Micromonospora, i.e. the presence of meso-diaminopimelic acid and N-glycolyl muramic acid in the peptidoglycan, whole-cell sugar pattern D, phospholipid type II, and cellular fatty acid type 3b. Phylogenetic analysis based on 16S rRNA gene sequences revealed a close relationship between strain P0402T and Micromonospora coxensis JCM 13248T (99.0% similarity), Micromonospora eburnea JCM 12345T (99.0%), Micromonospora marina JCM 12870T. (98.9%), Micromonospora halophytica JCM 3125T (98.7%), Micromonospora chalcea JCM 3031T (98.7%), Micromonospora purpureochromogenes JCM 3156T (98.6%) and Micromonospora aurantiaca JCM 10878T (98.5%). It could be clearly distinguished from these type strains based on low levels of DNA-DNA relatedness and phenotypic differences. On the basis of the data presented, strain P0402T is suggested to represent a novel species of the genus Micromonospora, for which the name Micromonospora humi sp. nov. is proposed. The type strain is P0402T (=JCM 15292T =PCU 315T =TISTR 1883T). © 2011 IUMS Printed in Great Britain.
