Many of us have a sweet tooth. So do some bacteria! Rhodoferax ferrireducens happily eats sugar. It converts 80% of sugar electrons into electricity! Just give it 1 sugar cube. The sugar crazy microbe will make electricity that ‘charges’ a cell-phone battery for four days! What would happen with a cup full of sugar? You would get 17 hours of light from a 60-watt bulb!
No sugar at home? No problem. Just give it fruits, beets and sugarcane! These contain simple sugars like sucrose, fructose and glucose. It eats xylose as well! This is in wood and straw. So, the next time you want a steady stream of electricity to charge some gadget, throw a sugar party. Make sure your guest list has only Rhodoferax ferrireducins on it!
