(a, c, and e) Growth of C. jejuni under anaerobic (a), microaerobic (c), and oxygen-limited (e) conditions in BHI-FCS medium with no added nitrate (open circles), with 20 mM sodium nitrate (open squares), and with 100 mM sodium nitrate (closed squares). (b, d, and f) Nitrite accumulation in culture supernatants under anaerobic (b), microaerobic (d), and oxygen-limited (f) conditions after addition of 20 mM (open squares) and 100 mM (closed squares) sodium nitrate.
