MYCOTOXINS OF PENICILLIUM STRAINS ISOLATED FROM SOILS OF UNDISTURBED AND ANTHROPOGENICALLY DISTURBED ECOSYSTEMS

Mycotoxins of 19 Penicillium strains (belonging to 12 species) isolate d from habitats subjected to strong anthropogenic stress and from undi sturbed extreme habitats were identified by means of chemical and phys icochemical methods. Strains of the species P. chrysogenum, P. vulpinu m, P. spinulosum, P. griseofulvum, and P. aurantiogriseum synthesized sets of secondary metabolites different from those known for these spe cies from the literature. No appreciable production of mycotoxins was revealed in the strains of species P. glabrum, P. dangeardii, Penicill ium sp., and P. funiculosum.
