Photosynthetic physiological analyses of the PSII and PSI in d-lactate producing strains. a Light response curve of rETR(II) of PSII. b Light response curve of Y(II) of PSII. c Oxygen evolution of the PSII under varied light intensities (from 0 to 2000 μmol photons m−2 s−1). d Light response curve of rETR(I) of PSI. e Light response curve of Y(I) of PSII. Prior to measurements, cells in the exponential phase were wash and re-suspended in fresh BG11 medium containing 50 mM NaHCO3. The experimental point are averages of three independent measurements; Error bars indicate the standard deviation (SD); if error bars are invisible, they are small than the data point symbol. Abbreviations: rETR(II), relative electron transport rate of PSII; Y(II), effect quantum yield of PSII. Error bars indicate the standard deviation (SD); if error bars are invisible, they are smaller than the label of the diagram
