Dear

Here some references at least for microbes. For furtehr details look  
at the website of our colleague Willy Verstraete.

If yoy like specific antifungal effects, this is more complex. But  
what is routinely used is treatment of the containers with ultrasound,  
which inhibits also development of algae.

activity of biogenic silver and its mode of action." Applied  
Microbiology and Biotechnology 91(1): 153-162.

antimicrobial agents: a useful development or a cause for concern?".
