Agromyces albus sp. nov., isolated from a plant (Androsace sp.).

Agromyces albus sp. nov. is proposed for an aerobic, oxidase- and catalase-positive actinomycete that was isolated from the above-ground part of a plant (Androsace sp., in the family Primulaceae). The strain is characterized by white colonies, fragmenting hyphae that penetrate into agar media and chemotaxonomic properties that are typical of the genus AGROMYCES: Analysis of 16S rDNA sequences confirmed that the strain belongs to the genus Agromyces and revealed its close phylogenetic relationship with Agromyces ramosus. DNA-DNA pairing studies showed that the strain belongs to a separate genomic species; this is consistent with its distinction from other Agromyces species at the phenotypic level. The G+C content of the DNA was 69.0 mol%. The type strain is VKM Ac-1800(T) (=UCM Ac-623(T)).
