Description	In a eutrophic lake and in an acid bog-lake, phytoplankton cells (bigger than 3 micrometers) acquired about three times higher fraction of 32P than bacteria if P was added as glucose-6-phosphate (G6P) than if added as orthophosphate. In an oligotrophic lake, no such preferential use of [32P]G6P was observed, nor preferential use of [32P]ATP in all the three lakes studied. Preferential use of G6P by phytoplankton cells coincided with the dominance of the same size fraction in particulate phosphatase activity, measured with 4-methylumbelliferyl phosphate (MUFP). Turnovers of [32P]G6P and MUFP were similar but 2-22 times slower than turnover of [32P]ATP. The nucleotide- and the non-nucleotide dissolved organic phosphorus thus may differ in turnover and significance for competition between bacteria and phytoplankton for P.
