Abstract
A Gram-positive, non-motile, rod-shaped bacterium strain NIO-1018T isolated from a mangrove sediment sample of the Chorao Island, Goa, India, was subjected to a detailed polyphasic taxonomic study. The strain designated as NIO-1018T matched with most of the phenotypic and chemotaxonomic properties of the genus Agromyces and represents a novel species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain NIO-1018T fell within the cluster comprising species of the genus Agromyces, clustering with Agromyces soli (98.1 %), Agromyces flavus (97.9 %), Agromyces aurantiacus (97.7 %) and Agromyces ulmi (97.3 %). The predominant menaquinone was MK-12, and the major cellular fatty acids were anteiso-C15:0, iso-C16:0, anteiso-C17:0 and iso-C15:0. The polar lipids consisted of diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C content of strain NIO-1018T was 71.8 mol%. The combination of phylogenetic analysis, DNA–DNA relatedness, phenotypic characteristics and chemotaxonomic data supported the view that strain NIO-1018T represents a novel species of the genus Agromyces, for which the name Agromyces indicus sp. nov. is proposed. The type strain is NIO-1018 (=JCM 17573T = CCTCC AB2011122T).
