Microalgal productivity was examined using both a wild type and a phycocyanin-deficient mutant of Synechocystis PCC 6714 (PD-1). The culture was conducted at various light intensities under low and high cell densities in a continuous culture system. At low light intensity, photosynthetic productivity was almost the same for both low and high cell densities. However, at higher light intensities photosynthetic productivity was higher in mutant PD-1 than in the wild type. At 2000 μmol photon m−2 s−1 the productivity was 50% higher in mutant PD-1. This result is consistent with our first report (Nakajima & Ueda, 1997), which showed that photosynthetic productivity can be improved by reducing the light harvesting pigment content in high cell density cultures at high light intensities. It is concluded that the technology for reducing LHP content is a useful method for improving photosynthetic productivity in algal mass production.
