Direct isolation of fungal hyphae degrading 2,4,5,6-tetrachloroisophthalonitrile from soil

Abstract

Fungal hyphae degrading 2,4,5,6-tetrachloroisophthalonitrile (chlorothalonil) were isolated directly from soil by the soil washing method. Based on the morphological characteristics, 53% of the isolates were classified into Fusarium spp. The application of the dilution plate method revealed that Penicillium spp. accounted for 50% of the isolates. These results suggested that Fusarium spp. were active as hyphae in chlorothalonil degradation in soil unlike Penicillium spp. © 2000, Taylor & Francis Group, LLC.
