In the biomasses from 17 moulds isolated in housing buildings, a Dugesia tigrina bioassay was carried out to assess the toxicity of Aspergillus versicolor sterigmatocystin (ST) producing strains. Making use of this method it was possible to test the fungal isolates of A. versicolor coming from the naturally infested construction materials of different housing buildings. The toxicity of the extracts prepared from the biomasses was in a wide range of LC 50 starting from non-toxic through weakly toxic (100-1000 mg dm-3), medium toxic (10-100 mg dm-3), and potently toxic (1-10 mg dm-3), in the latter case 8.2 mg dm-3 air-dry biomass of A. versicolor was highly productive and synthesized more than 500 mg kg-1 ST.
