Photosynthetic parameters of HS mutants. a Gross O2 evolution in response to increased irradiance of HydA1+, HS-14, HS-40 and HS-62 (black, green, blue and red, respectively). Dissolved O2 evolution was measured in a 5-mL vial fitted with Pyroscience FireSting O2 OXROB3 probe, and OXVIAL4 respiration vial. Error bars are in SE (n = 3). b Chlorophyll fluorescence measurement. ETR in response to increased irradiance of HydA1+, HS-14, HS-40 and HS-62 (black, green, blue and red, respectively) was measured using Walz Dual-PAM-100. Error bars are in SE (n = 3). c Autotrophic growth of HydA1+ and 3 HS clones: HS-14, HS-40 and HS-62 (black, green, blue and red, respectively) under aerobic conditions, measured in A680nm
