Figure 2.

A variety of crystal typologies; i.e., different morphologies, sizes, and chemical compositions can be produced by P. stutzeri AG259. (a) Whole, uncontrasted cell grown on Ag⁺-containing environment with large, triangular, Ag-containing particles at both poles; an accumulation of smaller Ag-containing particles can be found all over the cell. (b and c) Triangular, hexagonal, and spheroidal Ag-containing nanoparticles accumulated at different cellular binding sites.
