Their taxonomic positions were determined using a polyphasic approach. Chemotaxonomic characteristics of these strains coincided with those of the family Micromonosporaceae, i.e. cell wall chemotype II, N-glycolyl type of muramic acid, and type II phospholipids. Phylogenetic analysis based on 16S rRNA gene sequence data also indicated that these strains fell within the family Micromonosporaceae and formed a distinct taxon in the Micromonosporaceae phylogenetic tree. On the basis of phylogenetic analysis, characteristic patterns of 16S rRNA gene signature nucleotides and chemotaxonomic data, it is proposed that the novel isolates belong to a new genus, Actinaurispora gen. nov. The type species of the genus is proposed as Actinaurispora siamensis sp. nov., with strain CM2-8T (=JCM 15677TT =BCC 34762 ) as the type strain. DAP, diaminopimelic acid The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains CM2-8T and CM2-12 are AB454379 and AB465341, respectively. Phylogenetic trees based on almost complete 16S rRNA gene sequences constructed using the neighbour-joining, maximum-parsimony and minimum-evolution methods and tables giving the fatty acid composition and 16S rRNA gene signature nucleotide positions of strains CM2-8T and CM2-12 and related strains/species are available with the online version of this paper.
