Many microorganisms accumulate phosphor as polyphosphates. This paper highlights the great importance of filamentous microorganisms. So far the ability to store phosphorus in volutin granules by filamentous microorganisms has not been evaluated. The aim of this research was to prove the ability to store phosphorus in volutin granules as well as to show the meaning of potassium and magnesium ions in the phosphorus uptake by filamentous microorganisms that dominate the floating scum over the bioreactors liquid surface and monocultures of bacteria.
Electron microscopy and energy dispersive X-ray analysis was used to assess the composition of polyphosphate granules in filamentous bacteria.
