Oxalate film formation on marble specimens caused by fungus
Source abstract
Abstract
Abstract A study was carried out on the effects of a fungal strain on Carrara marble specimens in cultural experiments. The fungal strain, isolated from Pisa Tower, was identified as Sporotrichum genus. After 8 months’ incubation at 28 °C, an orange–brown film was formed. The FT-IR analysis of the film showed the presence of bi-hydrate calcium oxalates. A semi-quantitative evaluation was made by term-gravimetric analysis showing that the film composition was 66% oxalate, 16% calcite, a significant amount of phosphate and a low amount of nitrates.
