Sulfate reduction
Resumo:  The Minimal Inhibitory Concentration (MIC) of a biocide is usually determined by adding it in various concentrations to a suitable growth medium which is then inoculated with the test bacterium. These cultures are then observed for up to 28 days for growth of the organism as shown by its production of black ferrous sulphide. A method has been developed whereby the MIC of a biocide can be found within 4 days. Instead of noting ferrous sulphide production, this new method measures changes in: 1) optical density and 2) sulphate reduction of a logarithmic culture of the test strain exposed to the biocide.

La concentration minimale inhibitrice (MIC) d'un biocide est habituellement déterminée par addition du biocide à différentes concentrations dans un milieu de croissance approprié qui est alors inoculé par la bactérie testée. Ces cultures sont ensuite suivies pendant un maximum de 28 jours pour mettre en évidence la mise au point. Cette méthode n'étudie pas la production de sulfide ferreux mais mesure les variation de 1) la densité optique et 2) de la réduction des sulfates dans une culture en phase logarithmique de croissance de la souche testée, exposée à l'action du biocide.
