Abstract:
Ola leaf manuscripts from Sri Lanka date back to several centuries. While they have been well preserved over the last century, their condition has worsened in recent years when black dots caused by microorganisms started occurring on their surface. In this study, the current state of preservation and the factors causing deterioration are examined using microscopy techniques. Microscopic images clearly show that the manuscripts are contaminated by microorganisms which penetrated deeply into the carrier material, destroying the internal structure. A Penicillium griseofulvum strain was recognized as the most active microorganism in xylan degradation. Sri Lanka’s climate provides favorable conditions for the growth of these fungi. Therefore, it is suggested that temperature and humidity of the archival space should be better controlled in order to ensure the Ola leaf manuscripts’ long-term preservation.
