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.

Aksaray Yöresine Ait Volkanik Tüf Taşının Onarımında Biyomineralizasyon Yönteminin Etkisinin İncelenmesi

Öz

Tarihi yapılar, geçmişten günümüze ulaşan kültürel ve mimari birikimin önemli bir parçasını oluşturmakta ve toplumların tarihsel sürekliliğini yansıtmaktadır. Bu yapıların korunması ve özgün nitelikleriyle gelecek kuşaklara aktarılması büyük önem taşımaktadır. Bu çalışmada, Aksaray ve çevre illerde tarihi yapılarda yaygın olarak kullanılan volkanik tüf taşı üzerinde oluşturulan çatlakların, biyomineralizasyon yöntemi kullanılarak onarılabilirliği incelenmiştir. Çalışma kapsamında biyomineralizasyon potansiyeline sahip Bacillus cereus RSKK 683 ve Bacillus subtilis ATCC 6633 bakterileri kullanılarak, mikroorganizma kaynaklı kalsiyum karbonat (CaCO₃) oluşumu yoluyla çatlak kapatma davranışları değerlendirilmiştir. Uygulama sonrası elde edilen veriler; optik mikroskop görüntüleri ile birlikte taramalı elektron mikroskobu (SEM) ve enerji dağılımlı X-ışını analizi (EDAX) kullanılarak incelenmiştir. Elde edilen bulgular, her iki bakteri türünün de CaCO₃ oluşumu yoluyla çatlakların doldurulmasına katkı sağladığını ve biyomineralizasyon yönteminin volkanik tüf taşı gibi doğal yapı malzemelerinin korunmasında uygulanabilir bir onarım yaklaşımı sunduğunu göstermektedir.
