Cell concentrations of (A) chlorophyll a, (B) carotenoids, (C) phycocyanin, (D) allophycocyanin (APC), and (E) phycoerythrin (PE), in A. circinalis strains CS534, CS537 and CS541 growing in batch culture under optimal light for growth. Samples were taken at exponential phase (day 5). Vertical bars indicate standard deviations of at least three replicates. Different letters above the bars indicate means that are significantly different at p < 0.05).
