Protection and consolidation of stone heritage by self-inoculation with indigenous carbonatogenic bacterial communities [PDF]

Nature Communications, 2017
Salt weathering enhanced by global warming and environmental pollution is increasingly threatening stone monuments and artworks. Here, the authors present a bacterial self-inoculation approach with indigenous carbonatogenic bacteria and find that this ...

Biorestoration Potential of Carbonatogenic Bacteria on Lithotypes: SEM and AFM characterization [PDF]

BIO Web of Conferences
Background incl. aims. Microbially-induced calcium carbonate precipitation (MICCP), a bio-geochemical process, is a promising technology for eco-friendly applications particularly in the restoration of ornamental limestones. This study explores the efficacy of the biorestoration treatment using Lysinbacillus fusiformis 3.20 strain as a carrier for the ...

Carbonatogenic bacteria on the ‘Motya Charioteer’ sculpture [PDF]

Journal of Cultural Heritage, 2022
The ‘Motya Charioteer’ marble statue, a masterpiece of ancient Greek sculpting, was discovered in 1979 on the island of Motya, Sicily. A general assessment of the statue’s conditions in 2008 revealed that the marble has lost its luster and started to show some microcracks. In 2019 and in 2020, microbiological surveys were conducted to assess the marble’

Carbonatogenic Bacteria in the Maros-Pangkep Karst: Protectors or Threat to Prehistoric Paintings? [PDF]

Journal of Microbiology and Biotechnology
The Maros-Pangkep karst region hosts prehistoric cave paintings recognized by UNESCO as a world cultural heritage site. The presence of calcium carbonate (CaCO3) on the surface of these artworks suggests the involvement of carbonatogenic bacteria, which facilitate CaCO3 production or deposition.

Carbonatogenic Bacteria from Corallium rubrum Colonies

Minerals (Basel, Switzerland)
The precipitation of minerals, in particular carbonates, is a widespread phenomenon in all ecosystems, where it assumes a high relevance both from a geological and biogeochemical standpoint. Most carbonate rocks are of biological origin and made in an aquatic environment.
