Developed a process involving bacteria to repair faults in rocks & concrete

she & her team mix two common types of soil bacteria, Bacillus pasteurii and Sporosarcina ureae, with sand and “feed” the bacteria a rich solution containing both urea and calcium chloride; after using up the supply of nutrients, the bacteria die, but by that time, the calcium carbonate has crystalized the sand into solid limestone*when perfected, her process for creating & fixing limestone is expected to be used to restore such monuments as the foundation of the empire State Building & Mt. Rushmore
