"Using isothermal microcalorimetry to measure the metabolic activity of the mineral-associated microbial community in bioleaching" - Makaula, D.X., Huddy, R.J., Fagan-Endres, M.A., Harrison, S.T.L.  

  • Isothermal microcalorimetry is used to measure microbial activity on the mineral.
  • Microbial activity of a mixed mesophilic community colonising pyrite is quantified.
  • Metabolic activity increased with increasing attachment during early colonisation.
  • Metabolic activity can be measured directly from the humid mineral surface provided.
  • Using mineral coated beads, metabolic activity is determined on a surface area basis.
