ABSTRACT: Intracellular of carbon, nitrogen and phosphorus content in phytoplankton cells is traditionally measured using concentrates containing thousands to millions of cells. In the present study, we used a nuclear microprobe (NMP) to determine C, N and P concentrations in single filaments of 3 cyanobacteria species: Anabaena sp., Nodularia spumigena and Aphanizomenon flos-aquae var. klebahnii isolated from Baltic Sea water. Estimations of C, N and P content per cell were calculated and compared to the concentrations found using traditional bulk methods. No significant differences regarding the C, N and P cellular content were found between the 2 methods for each of the species tested (p < 0.05). From our results, we conclude that the NMP can be a useful tool for studying the elemental content of single phytoplankton cells.
