In the Earth’s lithosphere, fungi are of fundamental importance as decomposer organisms, animal and plant pathogens and symbionts (e.g. lichens and mycorrhizas), being ubiquitous in sub-aerial and subsoil environments. The ability of fungi to interact with minerals, metals, metalloids and organic compounds through biomechanical and biochemical processes, makes them ideally suited as biological weathering agents of rock and building stone. They also play a fundamental role in biogeochemical cycling of nutrients, (e.g. C, N, P and S) and metals (e.g. Na, Mg, Ca, Mn, Fe, Cu, Zn, Co and Ni) essential for the growth of living organisms in the biosphere. In addition they play an integral role in the mobilization and immobilization of non-essential metals (e.g. Cs, Al, Cd, Hg and Pb). Most studies on mineral-microbe interactions and microbial involvement in geological processes have concentrated on bacteria and archaea (Prokaryota): fungi (Eukaryota) have, to a certain extent, been neglected. This article addresses the role of fungi in geomicrobiological processes, emphasizing their deteriorative potential on rock, building stone and mineral surfaces and involvement in the formation of secondary mycogenic minerals. Such roles of fungi are also of importance for the global carbon reservoir and have potential biotechnological applications, e.g. in the bioremediation of xenobiotic-, metal- and/or radionuclide-contaminated soils and wastes, and metal/radionuclide recovery.

“…The raw materials of the cement have mainly the following constituents: 75% limestone (CaCO 3 ); 20% -25% clay (Al 2 O 3 + Fe 2 O 3 ); 5% sand (SiO 2 ) and 2% Ferric oxide (Fe 2 O 3 ). In fact cements are mineral materials, basically hydrated silicate and portlandite [Ca(OH 2 ) 2 ] for the ordi-nary Portland cement [5]. Cement adversely affects the populations of microorganisms.…”

Soil samples were collected from and around Zliten cement factory, Zliten town, Libya. Soil metals and microbial contents were determined. The results obtained for the examined physiochemical characteristics of soil in the area studied prove that cement dust from the Zliten cement factory in Libya has had a significant impact on the soil. The affected soil properties are pH and total calcium content. These characteristics were found to be higher than those in similar soils from the same area (unpolluted). The increment of soil pH in the same area may be a result of precipitation of cement dust over the years. Metal uptake from cement to plants and soil then affects organisms' bodies, a fact that seems to be reflected in this study. Different responses were found in each site. For instance, the dominance of fungi of soil was lowest at 100 m from the factory and the evenness and diversity increased at this site compared to 300 m from the factory and the control area.
