| Abstract: | Phosphate uptake kinetics of Synechococcus sp. WH7803 and Thalassiosiraweissflogii were studied in axenic batch culture. Phosphate-repleteSynechococcus sp. WH7803 cells have a lower affinity for inorganicphosphate (Pi) (Ks = 67 µmol l–1) than Pi-starvedcells (Ks = 3.1 µmol l–1). The Ks of Pi-starvedcells increased |
