What is Geomycology of Rock Weathering?

Geomycology of rock weathering examines fungal mechanisms in mineral dissolution, organic acid production, and biodeterioration of stone substrates in building materials.

Fungi produce chelating agents and acids that mobilize elements from rocks, forming mycogenic patinas on monuments (Sterflinger, 2000; 413 citations). Studies document bioweathering by species like Schizophyllum commune on black slate and chrysotile asbestos (Kirtzel et al., 2019; 52 citations; Daghino et al., 2008; 53 citations). Over 20 papers since 2000 quantify fungal roles in heritage conservation, with ~1,500 total citations across key works.

Key Challenges

Why It Matters

Fungal bioweathering accelerates deterioration of limestone Mayan buildings in semi-arid climates, as shown by Ortega-Morales et al. (2016; 60 citations) isolating 101 strains that dissolve carbonates. Bioprotection via biofilms stabilizes stone surfaces against further erosion (Gadd and Dyer, 2017; 63 citations). These processes inform conservation strategies for karst monuments, linking microbial activity to CO2 capture and elemental cycling (Lian et al., 2011; 49 citations), and enable bioremediation of hazardous minerals like chrysotile (Daghino et al., 2008).

Key Research Challenges

Quantifying Fungal Mineral Dissolution

Measuring exact contributions of fungal acids versus abiotic weathering remains difficult due to complex field conditions. Sterflinger (2000; 413 citations) notes variability in epilithic fungi effects on stone types. Lab assays often fail to replicate natural biofilms (Di Martino, 2016; 58 citations).

Distinguishing Bio- from Abiotic Deterioration

Fungal patinas mimic chemical weathering, complicating attribution in heritage sites. Dakal and Cameotra (2012; 183 citations) detail overlapping mechanisms in architectural heritages. Salvadori and Municchia (2016; 118 citations) highlight lichen-fungi synergies on monuments.

Developing Fungal Bioprotection Strategies

Harnessing fungi for stabilizing rock varnishes faces scalability issues in diverse climates. Gadd and Dyer (2017; 63 citations) describe biomineralization veneers but note inconsistent formation. Kirtzel et al. (2019; 52 citations) report basidiomycete pressure and acids aid but require optimization.
