| Abstract |
| Cultural heritage buildings of stone construction require meticulous restoration efforts to preserve them as nearly as possible to their original state. Environmental factors and human activity contribute to the degradation of these historic stone structures, posing considerable challenges for preservation. Traditional restoration techniques often involve invasive interventions that may alter the stone's structure and appearance. Recently, biotechnological approaches using bacteria represent a promising step toward sustainable and green heritage restoration techniques that respect the cultural significance and material authenticity of historic structures. This paper explores the use of bacteria, focusing on strains such as Bacillus Subtilis and Sporosarcina Pasteurii, through microbial-induced calcite precipitation (MICP) to fill cracks, reinforce weakened stone surfaces and bio-replicating intricate shapes and textures of lost stone material with mineral compositions closely resembling the original substrate. The paper seeks to create and distribute a detailed questionnaire to collect insights from restoration professionals, emphasizing their familiarity with bacterial restoration techniques, perceived advantages and limitations, and willingness to consider these methods. The questionnaire will cover areas such as prior knowledge of microbial-induced calcite precipitation (MICP), concerns about environmental and material compatibility, anticipated implementation challenges, and potential effects on the aesthetic and historical authenticity of stone structures. Results from this survey aim to bridge the gap between biotechnological innovations and heritage restoration practices, offering valuable feedback for researchers and practitioners to enhance bacterial application techniques for broader acceptance and practical use in conservation efforts. |
