Nocardioides astragali sp. nov., isolated from a nodule of wild Astragalus chrysopterus in northwestern China.

ABSTRACT: A Gram-positive, non-motile, rod-shaped bacterial strain, designated HH06^T, was isolated from a nodule of Astragalus chrysopterus in northwestern China. Phylogenetic analysis of the 16S rRNA gene sequence showed that the strain is closely related to Nocardioides alpinus Cr7-14^T and Nocardioides furvisabuli DSM 18445^T with 98.5 and 98.1% similiarity, respectively. Growth was observed at 4-28 °C in R2A medium (optimum at 25 °C), at 10-30 °C in YMA and LB medium (optimum in both at 28 °C) and at pH 5.0-10.0 in R2A medium (optimum at pH 7.0-8.0). The cell wall peptidoglycan was found to contain LL-diaminopimelic acid as the principal diamino acid and MK-8(H4) was identified as the predominant menaquinone. The major polar lipids were identified as phosphatidylin
