"We studied the impact of protistan grazing and phosphorus availability on the numbers and biomasses of bacteria from various phylogenetic lineages, and on their growth and activity parameters in the oligo-mesotrophic Piburger See, Austria. Enhanced grazing resulted in decreased proportions of bacteria with high nucleic acid content (HNA bacteria) and lower detection rates by FISH. Betaproteobacteria were heavily grazed while Alphaproteobacteria and Cytophaga-Flavobacterium-Bacteroides were less affected by predators. In the treatments enriched with phosphorus, Betaproteobacteria became dominant and successful opportunistic competitors for nutrients. In contrast, Actinobacteria did not respond to surplus phosphorus by population growth, and maintained their small size, which resulted in a very low biomass contribution. In addition, significant relationships between HNA bacteria and several bacterial phylogenetic clades were found, indicating an enhanced activity status." .
