18th-century frescoes in Valencia, Spain, restored using bacteria by researchers Pilar Roig and Pilar Bosch.
Researchers Pilar Roig and her daughter, Pilar Bosch, have created a technique to restore 18th-century frescoes in Valencia, Spain, using bacteria.
This method involves training bacteria to break down damaging animal collagen glue from a past restoration.
The bacteria produce enzymes that degrade the glue when mixed with an algae-based gel, allowing for quicker, effective restoration.
Their innovative approach has also been applied to other historical sites and is being tested for graffiti removal.
