Figure 1

Removal of A. baumannii from slightly acidic terra rossa (pH 5.40) supplemented with 1 wt% of natural zeolitised tuff (NZ) or 1 wt% of Cu-loaded NZ (CuNZ), or 1 or 0.1 wt% of Ag-loaded NZ (AgNZ). Bacterial counts represent averages of triplicate counts ± standard deviation. The detection limit was 1 CFU/g
