Gold Digging Bacterium Makes Precious Particles
We have learned in class that life can come in all sort of crazy shapes and sizes, as well as being able to live in conditions that most would not consider possible for life to even exist. Historically gold ions have been shown to effectively prevent microbial growth, however a newly discovered bacterium Delftia acidovorans can survive conditions with high quantities of gold ions by creating solid gold forms. They do this by creating a secondary metabolite which reduces gold in its ion form to its solid atomic form.
So stop what your doing, because there is gold in these petri dishes!
