The organic material present in oxalate patinas, collected from the stone external surfaces of the Baptistery in Parma (Italy), was analysed by GC-MS. The high racemisation levels determined for several specific amino acids indicate that microbial activity could contribute to the formation and modification of the organic material leading to the calcium oxalate patinas.

Abstract
The organic material present in oxalate patinas, collected from the stone external surfaces of the Baptistery in Parma (Italy), was analysed by GC-MS. The high racemisation levels determined for several specific amino acids indicate that microbial activity could contribute to the formation and modification of the organic material leading to the calcium oxalate patinas.File in questo prodotto:
