The effect of MMPP on the microbiological processes related to conversion of nitrogen and sulphur

These studies concern the effect of the concentration of MMPP (magnesium monoperoxyphtalate), a compound used (among others) in hygiene products (Lonzabac-MP) on the kinetics of microbiological processes involving the following species of bacteria: Bacillus licheniformis (denitrification), Desulfotomaculum ruminis (desulfurication) and Thiobacillus ferrooxidans (oxidation of iron II ions and reduced sulphur compounds). Results enabled determination of the microbiological activity of MMPP and the limits of its admissible and toxic (inhibiting transformation cycles of sulphur and nitrogen) concentrations.
