Research Guide

What is Bioremediation of Contaminated Building Materials?

Bioremediation of contaminated building materials uses microorganisms to remove or neutralize pollutants from construction waste and heritage stone surfaces.

Researchers apply calcifying bacteria and extremophilic microbes for stone consolidation and biodeterioration control. Key studies include Dhami et al. (2014) with 147 citations on bacterial remediation of cultural heritages and Jroundi et al. (2017) with 131 citations on self-inoculation with carbonatogenic bacteria. Over 10 papers since 2011 document bioaugmentation and biocleaning methods for limestone and sandstone.

Key Challenges

Why It Matters

Bioremediation enables sustainable cleanup of polluted heritage sites, such as European cathedrals and temples, reducing chemical use while preserving structural integrity (Dhami et al., 2014). It addresses nitrate salt efflorescence on stone via extremophilic bacteria, preventing aesthetic and physical damage (Romano et al., 2019). Applications extend to construction waste in temples like Beishiku, China, supporting environmental protection and cultural conservation (Zhang et al., 2023).

Key Research Challenges

Microbial Community Identification

Characterizing diverse biofilms on stone surfaces requires advanced sequencing to distinguish biodeteriorative from protective microbes. Skipper et al. (2022) used metagenomics on limestone, revealing complex microbiomes linked to deterioration. Grottoli et al. (2020) applied nanopore sequencing for rapid spoilage microorganism detection.

Delivery System Optimization

Selecting appropriate methods to apply biocleaning agents to stone and frescoes remains challenging due to substrate variability. Bosch et al. (2014) evaluated delivery systems for cultural heritage surfaces. Jroundi et al. (2017) tested self-inoculation for bacterial communities on heritage stones.

Long-term Efficacy Monitoring

Assessing bioremediation persistence against environmental weathering demands longitudinal studies. Villa et al. (2015) developed lab models of phototroph-heterotroph biofilms at stone-air interfaces. Gadd and Dyer (2017) examined biomineralization for built environment protection.
