Table 1. Cell size and dry cell weight of Synechocystis grown under increasing light intensities.
The turbidostat-controlled cultures were grown at constant temperature (30° C) and pH (8.0) under orange-red light and acclimated for 24 h at each light intensity. The values are mean and standard deviation derived from three biological replicates. (*) Point of recovery at 200 µmol photons m−2 s−1.
