This Bacteria Turns Sand Into Solid Stone. No Heat Required. Why Do Building Codes Reject It?

This Bacteria Turns Sand Into Solid Stone. No Heat Required. Why Do Building Codes Reject It? There is a way to turn loose sand into solid stone. No heat. No kilns. No cement. No chemical reactions requiring industrial equipment. It happens at room temperature. It happens in 72 hours. And the material it produces is the same mineral that built the pyramids, the Colosseum, and every great cathedral in Europe. The same mineral in seashells. The same mineral in your bones. It has been happening in ordinary soil for hundreds of millions of years. The thing doing it is a bacterium. The question is why you have never heard of it. The archive opens not in a construction site but in the dirt beneath your feet. Sporosarcina pasteurii has been living in soil, in caves, in lake sediments, and on the ocean floor for hundreds of millions of years. Microbiologists first catalogued it in the early 1900s. At the time it seemed like nothing more than a strange soil bacterium. Scientists knew the bacterium produced extraordinary amounts of an enzyme called urease — an enzyme that breaks down urea into carbonate ions that bind with calcium to form calcium carbonate crystals. They knew this for decades. It was a curiosity. A footnote in microbiology textbooks. A bacterium that did something interesting in a petri dish.
