Description:
A Gram-positive, yellowish bacterium strain AK-1Twas isolated from soil sample collected from peanut (Arachis hypogaea) crop field and studied by using a polyphasic approach. The organism had morphological and chemotaxonomic properties consistent with its classification in the genusAgromyces. Phylogenetic analysis of the 16S rRNA gene sequence showed that strain AK-1Twas closely related toAgromyces aurantiacus(98.6%) followed byAgromyces soli(98.3%),Agromyces tropicus(97.6%),Agromyces ulmi(97.3%),Agromyces flavus(97.2%), andAgromyces italicus(97.0%), whereas the sequence similarity values with respect to the otherAgromycesspecies with validly published names were between 95.3 and 96.7 %. However, the DNA-DNA hybridization values obtained between strain AK-1Tand other related strains were well below the threshold that is required for the proposal of a novel species. The DNAG+Ccontent of the strain is 71.8 mol%. The above data in combination with the phenotypic distinctiveness of AK-1Tclearly indicate that the strain represents a novel species, for which the nameAgromyces arachidissp. nov. is proposed. The type strain is AK-1T(=MTCC 10524T= JCM 19251T).
