Abstract

Abstract: The Jāmé Mosque of Isfahan or Masjed-e Jāmé is a historical mosque listed as a World Heritage Site by UNESCO in 2012. Tiles are one of the main materials used in this monument. This study was designed to assay the growth of fungi on the glazed tile and evaluating their alterations in the laboratory. Three fungi, Aspergillus niger and Parengyodontium album from outdoor of monument and Penicillium polonicum from indoor of monument, which were previously isolated, selected for this study. The axenic and mixed culture of the fungi was inoculated on glazed tiles (2.5 × 2.5 cm) with different colors of Mosaic, Anthracite blue and Soft fauna and incubated for 6 months at 28–30 °C. After six months incubation, the biodeterioration patterns were assessed via stereomicroscopy, scanning electron microscopy and colorimetry. The results showed that fungi have the ability to attach, grow and form crystals over the glazed tile surfaces. It seems that the growth pattern was affected by fungal species and color of tile. Modeling experiments can be used to evaluate fungal deterioration and to help prediction of appropriate time of restoration. Graphical abstract: Image 1 Highlights: The bioreceptivity and biodeterioration of Isfahan Masjed-e Jāmé glazed tiles was studied. Glazed tile models with three different colors were tested. Six-month laboratory colonization experiment was performed with the tiles inoculated by three fungi and mixed of them. Biogenic minerals were observed due to fungal growth. Bioreceptivity and biodeterioration was depended on tile color and fungal strain.
