As Spanish microbiologist Pilar Bosch was casting around for a subject to investigate for her PhD in 2008, she stumbled across a paper suggesting that bacteria, her field, could be used in art restoration, her mother’s own area of expertise.

當西班牙微生物學家皮拉爾‧博許2008年為她的博士學位苦思研究主題時，偶然發現1篇論文提及，細菌—她研究的領域，可能可以被用於藝術修復—她母親的專長領域。

At that same moment, her mother - Pilar Roig - was struggling to restore 18th-century paintings by Antonio Palomino in one of the oldest churches in Spain’s third city, Valencia.

與此同時，她的母親皮拉爾‧羅伊格正在西班牙第3大城瓦倫西亞最古老的1座教堂，努力修復18世紀安東尼奧‧帕洛米諾的畫作。

She was finding it particularly difficult to remove glue that had been used to detach the frescoes from the walls of Santos Juanes church during restoration work in the 1960s.

她發現，要去除之前在1960年代聖若望教堂修復期間，用來將壁畫與牆壁分開的膠水尤其困難。

The microbiologist trains bacteria by feeding them samples of the glue which was made from animal collagen. The bacteria then naturally produce enzymes to degrade the glue.

這位微生物學家透過餵食由動物膠原蛋白製成的膠水樣本訓練細菌，之後細菌自然產生酵素，降解膠水。

The family team mixes the bacteria with a natural algae-based gel and spread it on the paintings - which were taken from the walls in the 1960s. After three hours, the gel is removed, revealing glue-free paintings.

這個家庭團隊將細菌與天然藻類為基礎的凝膠混合，並將之散佈在畫作上，這些畫都是1960年代從牆上取下的。3個小時後，去除凝膠，展現沒有膠水的畫作。
