Abstract:

Twenty soil samples from Eastren, Westren, Northen an Southern directions of Gold and Silver manufactory in second industrial city, Riyadh, Saudia Arabia were collected and analyzed chemically for heavy metal concentrations, total solubal salts and pH and mechanically for composition of soils. Saturation percent were determined also. From soil samples collected thirteen fungal isolates were able to grew in media containing 10 mM of either aluminium or cobalt ions. Aspergillus were predominant and represented by four species. Fusarium and Penicillium were represented by 3 species. While Auerobasidium, Mucor and Monascus were represented by one species each. Intraspecific variability in growth response to Al3+ and Co2+ on agar media was studied among isolated fungi.
