Abstract:
A Gram-stain-positive, non-motile actinomycete, designated strain YIM 48875 T , was isolated from rhizosphere soil of Bletilla striata and its taxonomic position was established by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence data showed that strain YIM 48875 T belonged to the genus Planosporangium , supported by a bootstrap value of 100 %. Cells of strain YIM 48875 T showed two kinds of sporangia, which also supported its classification in the genus Planosporangium . Strain YIM 48875 T grew optimally at 28 °C, at pH 6.0–8.0 and in the presence of 2 % (w/v) NaCl. The level of 16S rRNA gene sequence similarity between strain YIM 48875 T and Planosporangium flavigriseum YIM 46034 T was 98.6 %. Strain YIM 48875 T exhibited a quinone system with menaquinones MK-9(H 4 ), MK-9(H 6 ) and MK-9(H 8 ) as the predominant compounds, a polar lipid profile comprising diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylinositol mannoside and the major fatty acids iso-C 15 : 0 and iso-C 16 : 0 ; these data were markedly different from those for P. flavigriseum YIM 46034 T . The level of DNA–DNA relatedness between strain YIM 48875 T and P. flavigriseum YIM 46034 T was 45.5 %. It is apparent from the genotypic and phenotypic data that strain YIM 48875 T represents a novel species of the genus Planosporangium , for which the name Planosporangium mesophilum sp. nov. is proposed. The type strain is YIM 48875 T ( = CCTCC AA 209049 T = KCTC 19779 T ).
