Nowadays, different bacteria such as Butyribacterium methylotrophicum, Eubacterium callanderi, and Peptostreptococcus productus and the strains Eubacterium limosum
, Ruminococcus productus, Clostridium scindens, Peptostreptococcus productus SECO-Mt75m3, and Eggerthella lenta SECO-Mt75m2 have been involved in the production of enterolignans [65,118].

The similarity of 16S rRNA gene sequences is 99% and 94% respectively between this bacterium and Eubacterium limosum
Butyribacterium methylotrophicum which can convert H2/CO2 into acetate through Acetyl-CoA pathway (Li et al.
