Abstract
Aim: To investigate
the mechanism of the interaction between montmorillonite and bacteria
by studying the reactions of different charges of montmorillonites with
bacteria.
Methods: Bacteriostatic
test: one loop of E. coli and Staphylococcus aureus at the concentration
of 1 x 10(6).mL-1 was incubated to the plate culture medium containing
different concentrations of montmorillonite, and incubated 24 h to observe
the growth of bacteria. Bacterial adsorptive test: different amounts of
montmorillonite were added into the artificially simulated intestinal
solution (containing bacteria 1 x 10(7).mL-1). After the culture, the
bacterial colonies were counted.
Results: The
results showed that montmorillonite per se showed no bacteriostatic or
bactericidal effect, but after exchange with metal ion and functional
groups which inhibits bacteria, then it showed these activities. Adsorption
was the main way between montmorillonite and bacteria. The special way
of fixing bacteria into the "carriage" of montmorillonite gel
which carry this structure was its pharmacological basis of curing diarrhea.
The adsorption effect was related to layer charge density of the montmorillonites.
Conclusion:
Montmorillonite showed adsorption ability of bacteria with minus related
to its layer charge, but has no bacteriostatic and bactericidal effect.
