Application of calcifying bacteria for remediation of stones and cultural heritages

A novel approach using calcifying bacteria to remediate stone degradation in cultural heritage sites, including the Taj Mahal, shows promise as a sustainable solution. The study highlights that microbial-induced calcium carbonate precipitation can effectively counteract biotic and abiotic factors causing deterioration, offering a more durable alternative to traditional conservation methods. This technique not only preserves the aesthetic appeal of historic monuments but also strengthens their structural integrity. The research emphasizes its potential as a future-oriented technology for heritage preservation, addressing both practical and theoretical aspects of cultural conservation.
