Abstract
The effects on photoinhibition of light-harvesting pigments in microalgal c ells were examined using the wild type and a phycocyanin-deficient mutant ( PD-1) of Synechosystis PCC 6714. Mutant PD-1 showed higher resistance to hi gh light than the wild type in terms of the decline of photosynthetic activ ity at any light intensity and with various cell densities. This suggests t hat the loss of productivity induced by high light intensity would be impro ved by reducing the content of light-harvesting pigments.
