    Recently, contamination of the environment by endocrine disruptive compounds, toxicity of these chemicals and their biodegradability are widely studied. This work is focused on estrogenity of chlorinated phenols and chlorbenzoic acids that represent potential degradation products of PCB compounds. Two different yeast bioassays for evaluation of estrogenity based on recombinated strains of Saccharomyces cerevisie were compared in this work. Estrogenic activity of chlorbenzoic acids varied with the chemical structure of chemicals. A mixture of chlorbenzoates (initial concentration 10 ppm) was degraded by a ligninolytic fungus Panus tigrinus in liquid cultures. Chemicals resulting from degradation were tested for their estrogenity, however, results indicated that the test responses were inhibited probably by some compounds present in the fungal culture liquid
