Protein synthesis by lake plankton measured using in situ carbon dioxide and sulfate assimilation / by Russell L. Cuhel and David R.S. Lean.: En13-5/86-143E-PDF
"The estimation of 'growth' of planktonic communities has been complicated by an inability to separate growth of bacteria which use organic substrates from algae that fix carbon dioxide for growth. Quantification of carbon recycling via algal respiration and excretion also remains elusive. These problems were avoided by measuring protein production. Furthermore, the subcellular composition of other newly formed biopolymers(carbohydrate and lipid) was estimated. These methods provided doubling times for the plankton population of 10 to 20 days instead of the 3-5 days from previous methods. This information makes the modelling of transport rates of nutrients much different. Recyling through zooplankton grazing is in balance with growth. Such food chain studies are a prerequisite for contaminant process studies. As part of the present study, pathways for sulfate metabolism in a lake ecosystem are also described"--Management perspective.
