Booth at the USA Science & Engineering Festival
Booth at the USA Science & Engineering Festival
With the Microbial Science Initiative at Harvard (MSI) we prepared and held a stand on how microbes are involved in making various food (“Microbes : the invisible chef”). We put an emphasis on linking characteristics directly observable (smells, consistencies, colors…) with microbial activity, to demonstrate that microbes have a crucial role in the making of lots of our favorite aliments. The 5th USA Science & Engineering festival in Washington, D.C., attracted over 300,000 visitors !
