Value 40 Percent
Organism Bacteria Escherichia coli

Method The effect of montmorillonite (concentration of 50 ug/ml) the survival of E. coli MC-6 in estuarine water was also tested, in the presence and absence of this clay, in chambers containing washed cell suspensions.
Comments Montmorillonite addition extended the time needed for a 50% reduction of the viable cell population (t1/2) of cells by 40% over the t1/2 of cells in River water alone. The effect of this clay was not significantly greater between 50- to 1,000 mug/ml montmorillonite concentrations.
