Turning brewery wastewater into battery power

CU Boulder engineers have developed an innovative bio-manufacturing process that uses a biological organism cultivated in brewery wastewater to create the carbon-based materials needed to make energy storage cells. This unique pairing of breweries and batteries could set up a win-win opportunity by reducing expensive wastewater treatment costs for beer makers while providing manufacturers with a more cost-effective means of creating renewable, naturally-derived fuel cell technologies.

“Breweries use about 7 barrels of water for every barrel of beer produced,” said Tyler Huggins, CU Boulder’s Department of Civil, Environmental and Architectural Engineering. “And they can’t just dump it into the sewer because it requires extra filtration...

Researchers with the Virginia Tech Center for Drug Discovery have identified a compound that blocks the growth of a fungus that causes deadly lung infections and allergic reactions in people with compromised immune systems. The research team targeted the switch that allows the fungus Aspergillus fumigatus to survive in iron-deficient conditions like the human body. Specifically, they targeted an enzyme known as SidA, which is essential for the synthesis of siderophores that are made during infection to steal iron from human proteins.

Furthermore, by performing high-throughput screening in the center’s Dr...
