Abstract
A Gram-stain-positive, aerobic, rod-shaped, yellow actinobacterium, designated MNA2T, was isolated from a hexachlorocyclohexane-contaminated soil in North India. Strain MNA2T showed 95 % 16S rRNA gene sequence similarity with Microbacterium halotolerans YIM 70130T. Phylogenetic analysis of 16S rRNA gene sequences showed that strain MNA2T belonged to a clade represented by the genus Microbacterium of the family Microbacteriaceae. Strain MNA2T contained anteiso-C15 : 0, anteiso-C17 : 0, iso-C16 : 0 and iso-C15 : 0 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 MNA2T belongs to a previously unrecognized species of the genus Microbacterium, for which the name Microbacterium lindanitolerans sp. nov. is proposed. The type strain is MNA2T (=DSM 22422T =CCM 7585T).
