Abstrakt: Many enzymes, such as laccases, are involved in the saprotrophic lifestyle of fungi and the effects of those may be linked to enhanced bioweathering on stone surfaces. To test this hypothesis, we studied the decomposition of kerogen-enriched lithologies, especially with black slate containing up to 20% of C org . Indeed, a formation of ditches with attached hyphal material could be observed. To address enzymes involved, proteomics was performed and one group of enzymes, the multicopper oxidase family members of laccases, was specifically investigated. A role in bioweathering of rocks containing high contents of organic carbon in the form of kerogen could be shown using the basidiomycete Schizophyllum commune, a white rot fungus that has been used as a model organism to study the role of filamentous basidiomycete fungi in bioweathering of black slate.
