Bacteria That Make Gold Nuggets

By February 6, 2013

Follow me on:

Pure native gold.Scientists have discovered a species of bacteria that produces solid gold. The gold atoms clump together to form nuggets. Delftia acidovorans generates the metallic gold to protect itself against toxicity from soluble gold. Metallic gold is relatively inert. You can wear it as jewelry and even eat it. However, gold ions are reactive and poisonous. Canadian researchers have identified the genes in the bacteria that produces the compound delftibactin that precipitates gold ions. While it's unlikely you can culture the bacteria to make yourself rich overnight, the discovery may allow for better recovery of gold from slurries and clean-up of toxic waste water from gold mines. You can read more about the discovery in Nature Chemical Biology.

No, Ben, few things sound more stupid and intolerant that mocking a second language learner. How’s your Mandarin? Tagalog? Urdu? I’m guessing you only speak English, right? How does that make you smart? Any infant can speak his mother tongue in two or three years.

Leave Ben alone. he’s right. That guy is not using English as a second language, but merely dumb substandard abbreviations. So Ben’s not the d-bag, you are :)
