Three new species of the genus Actinobispora of the family Pseudonocardiaceae, Actinobispora alaniniphila sp. nov., Actinobispora aurantiaca sp. nov. and Actinobispora xinjiangensis sp. nov.
The genus Actinobispora Jiang et al. is characterized by the formation of longitudinally paired spores on both the vegetative and the aerial mycelium, absence of mycolic acid, cell wall chemotype IV (containing meso-diaminopimelic acid as the diamino acid, galactose and arabinose), PVI and MK-9(H2). Comparative studies of morphology, chemical classification and phylogenetic analysis based on the 16S rRNA sequences among the four type strains of the genus Actinobispora and type strains of related genera were carried out. The results indicated that the genus Actinobispora is different from these other genera and should be placed in the family Pseudonocardiaceae Embley et al. 1988 with the genera Amycolatopsis, Pseudonocardia, Saccharomonospora, Saccharopolyspora and Actinopolyspora. On the bases of these results, three new species under the names of Actinobispora alaniniphila sp. nov., Actinobispora aurantiaca sp. nov. and Actinobispora xinjiangensis sp. nov. are proposed; the type strains are CCTCC AA97001T, CCTCC AA97002T and CCTCC AA97020T.
