Strain NL15-2K was isolated from soil by screening for bacteria capable of catabolizing lignin-related aromatic acids. This isolate was identified as a Streptomyces sp. on the basis of morphology and an analysis of its 16S rRNA gene sequence. NL15-2K utilized caffeic acid, coniferyl alcohol, ferulic acid, isovanillic acid, protocatechuic acid, vanillic acid, vanillin, and veratric acid as sole carbon sources.
