Anaerobic growth of Denitratisoma sp. strain DHT3 with estradiol under denitrifying conditions and under different vitamin-supplementing conditions. (A) Anaerobic growth of strain DHT3 using estradiol as the sole substrate under denitrifying conditions. (B) Anaerobic growth of strain DHT3 on estradiol in the medium supplemented with different vitamins or without vitamins. Bacterial growth was measured based on the increasing total protein concentrations in the cultures. Results are representative of 3 individual experiments. Data shown are means ± SEM of 3 technical replicates.
