Bacteria-Powered Light Bulb Is Electricity-Free

Image
Bacteria is experiencing a boon as of late. Just recently, microorganisms have been used to make a better sunscreen. Another bright idea comes from scientists who are using bacteria as the key ingredient in a biological light bulb that requires no electricity.

Created by three undergraduates at the University of Wisconsin, Madison, the so-called Biobulb will include a genetically engineered species of E. coli bacteria, the kind living inside the intestines of humans and other animals. Normally, these bacteria don’t glow in the dark, but researchers plan to introduce a loop of DNA to the microbes that will give them the genes for bioluminescence. The bacteria will glow like lightning bugs, jellyfish and bioluminescent plankton.
