Spanish woman trains bacteria to help restore 18th century paintings

Spanish microbiologist Pilar Bosch is training bacteria to help her mother, Pilar Roig, in restoring Antonio Palomino's 18th-century paintings in one of the oldest churches in Spain's Valencia. Bosch uses bacteria to remove glue, used to pull the paintings from walls in 1960s. She trains bacteria by feeding them glue samples. Bacteria then naturally produce enzymes to degrade the glue.
