Short-term H2 photoproduction under anaerobiosis. H2, O2 and CO2 exchange was measured using a membrane inlet mass spectrometer (MIMS) in D66 wild-type (W.T, n = 3) HydA1+ (n = 7) and 3 HS clones: HS-14 (n = 7), HS-40 (n = 7) and HS-62 (n = 3) (dash, black, green, blue and red, respectively). 180 µmol photons m−2 s−1 light was switched on at t = 0. SE is represented by error bars. a H2 production rate. b Dissolved O2 concentration. SE is represented by painted area in the corresponding sample color. c CO2 exchange rate
