Contribution à l’étude de l’effet bactéricide de l’argile sur escherichia.

Abstract

We conducted a study on Maghnia's Bentonite-clay to see its antibacterial effect onto the bacteria Escherichia coli. The first step was to re-identify the strain by microbiological and biochemical tests, these tests had given positive results, and the second part is about the clay: sieving, sterilization and finally dilution to do the antibiogram.

The study of the synergistic effect of acids and bentonite indicated the presence of signify antbactericidal effects. And also the results demonstrate that the antimicrobial capacity of Cu^{2 +}/montmorillonite was very effective on Escherichia coli.
