Aspergillus sclerotiorum: riesgo para la herencia cultural y la salud

Abstract

By performing a mycological culture, we isolated a fungal strain from a mold patch in a book of great heritage value from the "Coronado" archives. Ribosomal DNA sequencing identified the strain as Aspergillus sclerotiorum. By qualitatively determining its cellulolytic, proteolytic and amylolytic and enzymatic activities, as well as the production of pigments and acids, we confirmed its paper deteriorating abilities. Quantitatively, we evaluated its total cellulase enzyme activities on filter paper (FPase) and β-endoglucanase, and FPase and β-endoglucanase; confirming low activities. Although its deteriorating abilities are weak, it poses a threat to the preservation of the document and is a potential health hazard to the people who refer to and archive these books.

Estudio de la flora fúngica identificada en el Protocolo Ambulante de los Conquistadores 1533-1538 y del entorno donde se conserva.

“…En la actualidad existe una variedad de técnicas adecuadas y seguras para investigar el biodeterioro fúngico en el Patrimonio documental, sin embargo el aislamiento en medios de cultivo y la identificación de las especies según su morfología, continúa siendo la técnica de análisis convencional más utilizada por los investigadores y conservadores de patrimonio documental (Carrazana et al, 2014) método utilizado en la presente investigación.…”
