"We studied biomass reallocation within different phylogenetic lineages of bacteria under varying regimes of protozoan grazing and nutrient supply in the oligo-mesotrophic Piburger See (Austria). Size-fractionated treatments were incubated in bottles with and without added phosphorus (P) and in dialysis tubes for 96h. The release of bacteria from grazing resulted in a small increase in total abundance, but more pronounced changes of production and biomass. Addition of P to bottles seemed to indicate P limitation of bacterial growth. While Betaproteobacteria abundance and biomass increased greatly in P-surplus bottles (4x and 12x, respectively), biomass increased even more in the dialysis tubes (28x). By contrast, although Actinobacteria numerically dominated in the lake, their contribution to total biomass was always low. Our results illustrate that the quantification of the biomass of specific lineages may allow for a better assessment of C and P fluxes." .
