To determine genomic relatedness, DNA–DNA hybridization
was performed by using a modification of themethod of Ezaki
et al. (1989). Strain BR-34T exhibited relatively low levels of
DNA–DNA relatedness with the type strains of C. acidiphila
(45.32 %), C. yoronensis (43.89 %), C. subtropica (42.45%)
and C. rubra (38.13 %). It may be concluded from the above
results that strain BR-34T should be recognized as a representative
of a novel species of the genus Catenulispora, for which
we propose the name Catenulispora graminis sp. nov
