FIG. 3.

Anaerobic growth of “A. aromaticum” strain EbN1 with aromatic substrates under nitrate-reducing conditions. Cultures were inoculated with cells adapted to anaerobic growth with ethylbenzene (A), p-ethylphenol (B), acetophenone (C), or p-hydroxyacetophenone (D). Inoculated fresh anoxic media contained as a single aromatic substrate ethylbenzene (□), acetophenone (○), p-ethylphenol (⋄), or p-hydroxyacetophenone (▵). Filled symbols represent the adaptation substrate of the respective inoculum culture.
