Table 1 Strains used, and presence of glycerol/diol dehydratase (GDH) and β–glucuronidase (B-GUS) encoding genes. The presence of gdh was predicted by metagenome analysis of human feces [24] and was confirmed for the used strains based on genome analysis ( The presence of b-gus was predicted by Dabek et al. [26] and McIntosh et al. [27]
