Abstract


Pathogenic bacteria transmitted to humans through water are, nowadays, responsible for various infectious diseases; mainly gastrointestinal. Several disposal methods for these pathogens, such as chlorination, ozonation, and UV Rays have been used and developed.
Our study consists of using a new approach to deal with resistant strains that exist in wastewater; by the application of synthetic materials, the potassium permanganoferrates K3FexMnyO8 (1≤x/y≤4).
Our results show the antibacterial effect of these products tested in liquid and solid medium depending on the pH on three bacterial strains: Pseudomonas aeuruginosa (Ps.Ae), Escherichia coli (E.Co) et Staphylococcus aureus (St.Au.). In the presence of the potassium permanganoferrates, bacterial growth decreases by half in the liquid medium, with concentrations going from 0.74 mmol/l up to 0.023 mmol/l, depending on the Fe/Mn ratio and on the studied bacteria. In the solid medium, the inhibitive efficiency of K3FexMnyO8 is also demonstrated for optimized concentrations, between 0.74mmol/l and 0.023mmol/l.
The maximum inhibitions in the liquid medium are 99.4% for E.Co. and 99.9% for St.Au., are obtained with concentrations of 0.5 mmol/L of K3FexMnyO8 (Fe/Mn=4). However, with 1.2 mmol/l of permanganoferrates, the inhibition doesn't exceed 98.8% for Ps.Ae.
