Ashes as effective biocides of microbiological processes

The influence of fly ash from the "Karolin" heat and power producing plant in Poznan on the kinetics of processes taking place with involvement of the bacteria Desulfotomaculum ruminis and Thiobacillus ferrooxidans has been studied under laboratory conditions. The results indicate that the presence of fly ash has an inhibitory effect on the processes related to the microbiological conversion cycle of sulphur compounds and can be used as biocides in the processes of microbiological corrosion of materials.
