“In Penascola Bay in Florida, the proportion of phycocyanin-rich to phycoerythrin-rich strains of Synechococcus decreased dramatically from ~ 20 PSU to 28 PSU, i.e. PC-rich cells were an order or magnitude higher in abundance in the upper, lower salinity, part of this estuary.”
“This size class was consistently phycocyanin (PC) - rich.”
