US$1 banknote was imprinted on an agar gel plate containing a nutrient medium for 5 minutes and removed. Bacteria and fungal spores transferred by the imprinting process started to grow on the agar plate (poured on a large plate) and formed colonies. Here is a color-enhanced image after 5 days of development. Bacterial colonies look like drops of a liquid (compact and shiny) but fungal colonies look grainy as the hyphae grow each separately - dark mold colonies appear near the left margin. The microorganisms (germs) grew only where the dollar bill was in contact with the agar gel. The image indicates that banknotes harbor a wide variety of microorganisms and that it is a good idea to wash one's hands after handling paper money | |
