Comparison of N. europaea growth characteristics and NH4+ to NO2 conversion stoichiometry during NH3- and O2-limited steady-state growth

  • a Average values from 3 sampling days or 10-day steady-state period, ± standard deviations (see Table S1 in the supplemental material).

  • b The NH4+ concentration of the influx medium (60 mmol liter−1) multiplied by the influx rate (0.24 liter day−1).

  • c Sum of effluent NH4+ and NO2 concentrations.

  • d Letters A and B represent highly significant differences (P ≤ 0.01), and letters C and D represent significant differences (P ≤ 0.05) within parameters. Capital letters represent comparisons between 10-day periods, whereas lowercase letters represent comparisons between 3-day periods.
