The level of DNA–DNA relatedness among strains VF70612 S1T,
VF70612 S4 and VF70612 S5 ranged from 75–100%. In contrast,
DNA relatedness performed with R. radiotolerans was 47.75 ± 0.65.
These data were in accordance with RAPD analysis, which showed
that the three strains had the same pattern (Fig. S2), indicating that
they belonged to the same species.
