Effect of the Biomineralization Method on the Repair of Volcanic Tuff Stone from the Aksaray Region
Abstract
Historical structures represent an important part of cultural and architectural heritage that has been transferred from the past to the present, reflecting the historical continuity of societies. The conservation of these structures and their transmission to future generations while preserving their original characteristics is therefore of great importance. In this study, the applicability of a biomineralization-based repair approach for sealing cracks formed on volcanic tuff stone, which is widely used in historical structures in Aksaray and surrounding regions, was investigated. Within the scope of the study, Bacillus cereus RSKK 683 and Bacillus subtilis ATCC 6633, known for their biomineralization potential, were used to evaluate crack-healing behavior through microbially induced calcium carbonate (CaCO₃) precipitation. The results were examined using optical microscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray analysis (EDAX). The findings indicate that both bacterial strains contributed to crack filling through CaCO₃ formation, demonstrating that biomineralization is a feasible and environmentally friendly repair approach for the conservation of natural building stones such as volcanic tuff.
