Content of mycotoxins in conidiospores from mould in buildings.

Extraction and disintegration processes that allow processing of conidiospores apart from the rest of the culture have been tested. The mechanical disintegration with a ball mill and glass granule addition (φ 2-3 mm) was the most efficient. From the conidiospores of six pure cultures of wild strains from mould infested indoor areas, out of which four were toxin positive strains, patulin, gliotoxin, aflatoxin B1 and G1, ochratoxin A and satratoxin H were quantified in a concentration range of 0,004 µg till 10,3 µg/10(7) respectively 10(8) conidiospores.
