Kroppenstedtia eburnea DSM 45196T and Kroppenstedtia pulmonis W9323T are aerobic, Gram-positive, filamentous, chemoorganotrophic thermoactinomycetes. Here, we report on the complete and circular genome assemblies generated using Illumina MiSeq and Oxford Nanopore Technologies MinION reads. Putative gene clusters predicted to be involved in the production of secondary metabolites were also identified.
