Fig. 2. — Nitrification activity and microbial community analysis of culture A31 (isolation source of strain A67). NO₂^– (closed circle) and NO₃^– (open circle) in culture A31 by subculturing on ULAC medium (pH 5.5) containing 0.75‍ ‍mM urea. NO₂^– was not detected during the incubation, and complete nitrification from urea to NO₃^– was observed. The experiment was conducted without replication. However, re-experiments provided similar results (data not shown).
