Figure 4: Gas metabolism of Spironucleus vortens in a stirred cell suspension of 7.4 x 105 cells/ml in air-saturated phosphate buffered saline at 20°C, analysed by membrane-inlet mass spectrometry. Rates of O2 consumption, H2 production and CO2 production were derived from linear regression at the indicated tangents (standard deviation and number of replicates are denoted in brackets).
