Escherichia coli  uses sodium to build structures where it remains dormant. A little water is enough to wake her.

Crystallization . The bacterium Escherichia coli , one of the most studied by biologists microorganisms, is capable of controlling the crystallization of sodium chloride for biomineral creates three-dimensional structures within which they hibernate.

A safe haven

"It was a complete surprise, a totally unexpected result," says José María Gómez, Spanish biologist. It was at his home, with a simple microscope public, he noticed the strange behavior of drops immersed in saltwater bacteria. After a few hours, they form structures biosalines altering the crystallization of sodium chloride. These models are three-dimensional and are shelters in which Escherichia goes dormant. Just rehydrate all for bacteria to wake up.
