Comments "Under optimal conditions, Synechococcus 7002 displays growth rates which rank among the fastest reported for any cyanobacterium. While the underpinnings of a high growth rate are not fully understood, this phenotype may partly arise from a naturally high PSII to PSI ratio (typically ~0.5) (BNID 111246), relatively high chlorophyll (Chl) content per cell, and low phycocyanin (PC) to allophycocyanin (APC) ratio (2:1) of the phycobilisome (primary source)."
