Fig. 4: Microrespirometry-based N2O and O2 reduction during methanol oxidation by N2OR-containing methanotrophs.

N2O and O2 reduction by cells of Methylacidiphilum caldifontis IT6 (A) and Methylocella tundrae T4 (B) during methanol oxidation. Filled blue dots represent dissolved N2O, filled orange dots represent dissolved O2, and filled black dots represent N2O reduction rates. Experiments were performed in a microrespirometry (MR) chamber fitted with O2 and N2O microsensors. The red arrows mark the addition of 14–33 µM O2 into the MR chamber. The red- and green-marked numbers close to the red and green lines represent the N2O reduction rates before and during O2 reduction (gray-shaded area) in the MR chamber, respectively. Source data are provided as Source Data file.
