Abstract

A Gram-stain-positive, aerobic, rod-shaped, yellow actinobacterium, designated MNA2, was isolated from a hexachlorocyclohexane-contaminated soil in North India. Strain MNA2 showed 95 % 16S rRNA gene sequence similarity with YIM 70130. Phylogenetic analysis of 16S rRNA gene sequences showed that strain MNA2 belonged to a clade represented by the genus of the family . Strain MNA2 contained anteiso-C, anteiso-C, iso-C and iso-C as the predominant fatty acids and diphosphatidylglycerol, phosphatidylglycerol and two unknown polar lipids. The menaquinones were MK-12, MK-11, MK-13 and MK-10, in an approximate molar ratio of 45 : 40 : 13 : 3, respectively. The DNA G+C content was 65.3 mol%. The peptidoglycan was of the B type of cross-linkage with ornithine as the diagnostic diamino acid. The results of the phylogenetic, phenotypic and chemotaxonomic analysis indicate that strain MNA2 belongs to a previously unrecognized species of the genus , for which the name sp. nov. is proposed. The type strain is MNA2 (=DSM 22422 =CCM 7585).
