Kefir is one of the world’s oldest fermented food products and considered to be a ‘superfood’ with many purported health benefits
New research shows how cooperation among bacterial species allows kefir to thrive as a community

To make kefir, it takes a team. A team of microbes.
That’s the message of new research from EMBL and Cambridge University’s Patil group and collaborators, published in
