Table 1 Microrespirometry-based substrate-specific N2O- or O2-reduction rate by Methylocella tundrae T4 cells grown under anoxic and suboxic growth conditions
From: Nitrous oxide respiration in acidophilic methanotrophs
Condition | Rate (mmol·h-1·g DW-1) |
|---|---|
Maximum respiration rates of anoxic CH3OH + N2O-respiring cells |  |
 N2O respiration (at 0 µM O2; electron donor CH3OH; at the first 4 spikes of N2O) | 1.12 ± 0.01 |
 N2O respiration (at 0–5 µM O2; electron donor CH3OH; at the 5th spikes of N2O) | 0.64–0.68 |
 N2O respiration (at O2 > 5 µM; electron donor CH3OH) | 0.13–0.24 |
 O2 respiration (at O2 > 5 µM; electron donor CH3OH) | 1.02–1.07 |
Maximum respiration rates of suboxic CH4 + N2O + O2-respiring cells |  |
 N2O respiration (at 25–60 µM O2; electron donor = CH4) | 1.58−2.47 |
 N2O respiration (at 5–170 µM O2; electron donor = CH4) | 1.32 ± 0.25 |
 O2 respiration (at 25–60 µM O2; electron donor = CH4) | 0.98–2.37 |
 O2 respiration (at 5–170 µM O2; electron donor = CH4) | 0.95 ± 0.09 |
