The genomic
DNA of Escherichia coli strain B (Sigma-Aldrich) was used
as a standard. DNA–DNA hybridization was performed
between strain THG-SQA8T and S. multivorum KACC
14105T and S. ginsenosidimutans KACC 14526T fluorometrically
with photobiotin-labelled probes in microplate
wells (Ezaki et al. 1989).
