Microbial Applications and Properties

The video explores six bacteria with extraordinary abilities, likening them to superheroes. Geobacter metallireducens generates energy using electricity, Deinococcus radiodurans withstands extreme radiation, and Ideonella sakaiensis digests plastic. Caulobacter crescentus produces a powerful adhesive, Aquifex thrives in high temperatures, and Neisseria gonorrhoeae exhibits remarkable strength. These bacteria demonstrate unique adaptations that could have practical applications, from waste management to industrial uses.

What unique method does Geobacter metallireducens use to generate energy?
