Truncation of the algal light-harvesting antenna is expected to enhance photosynthetic productivity. The wild type and three mutant strains of Synechocystis sp. strain 6803 with a progressively smaller phycobilisome antenna were examined under different light and CO₂ conditions. Surprisingly, such antenna truncation resulted in decreased whole-culture productivity for this cyanobacterium.
