%X white-rot fungi have demonstrated a high capacity to degrade organic pollutants, including the insecticide lindane (y-hch). the purpose of this study was to eval¨²ate the degradative capacities of several white rot fungi species, bjerkandera adusta, irpex lacteus, lentinus tigrinus, phanerochaete chrysosporium, phanerochaete s¨®rdida, phlebia radiata, pleurotus eryngii, poliporus cialatus, and stereum hirsutum. fungal tolerance to various concentrations of a-, (3-, y- and 8 isomers of hexachlorocyclohexane (hch) was studied in both liquid and soil media samples. 8- and y-hch isomers showed the highest inhibition of fungal growth of all hch isomers. p. chrysosporium and b. adusta exhibited a high tolerance to hch pollution. the 8- and y-hch isomers were degraded between 15.1 and 70.8% by six of the nine fungal species, b. adusta, p. ciliatus, l. tigrinu, s. hirsutum, p. eryngii, and i. lacteus; [3-hch was 56.6, 26.5 and 23.9% degraded by b. adusta, p. ciliatus and p. eryngii, respectively in non-sterile soil, all the hch isomers were degraded between 8.2 and 17.5% by b. adusta immobilized on corncobs or woodchips. in nonsterile soil, other soil microflora showed an antagonistic effect on white-rot fungi catalyzed degradation of hch isomers.
