摘要: Planktonic heterotrophic bacteria (bacterioplankton) are now recognized to be a large and metabolically active group that contributes significantly the biomass flow of carbon in aquatic systems. Various methods available determine bacterial production (BBP), those employ radiolabeled precursors estimate rate synthesis nucleic acids proteins have become most widely used focus this chapter. In chapter, rationale, advantages, disadvantages commonly based on incorporation thymidine (TdR) leucine (Leu) discussed. addition, empirically conversion factor from or cells produced is presented as well several procedures designed test various assumptions these methods. Alternative BBP do not rely uptake compounds also discussed The measurement chapter total provide information relationship between diversity metabolism. concludes with review novel combine measurements microscopy molecular techniques proportion active, contribution specific phylogenetic groups.
