Method Photosynthesis was measured as oxygen evolution (net oxygen evolution and dark respiration) and fluorescence (variable fluorescence vs. maximum fluorescence, Fv:Fm).
Comments The obtained pKa values obtained in this study (Table 2), when combined with literature data (Naja et al., 2005), revealed that the carboxylic groups dissociation constants (pKa~5.5) and the dissociation constant of cis-CO2H isomer or phosphorous protonated sites on aromatic chains (Ph3P+CH2COPh) at pH values of ~6.25 were the dominant functional groups aiding the adsorption.
