Here is an interesting article about a PhD student at the University of Saskatchewan researching how to better protect beer from bacterial contaminiation. Here is my favorite quote:
Back in 2006, my three brothers made homemade beer. But the beer turned out so disgusting and contaminated that I decided to bring some to the lab. I grew the contaminating bacteria from the beer, and sequenced some of their DNA. I found three types of bacteria that have never been found in beer before, and identified a specific beer-spoilage or antimicrobial resistance gene in each type.
Pretty interesting.
