Title: Biodegradation Of Pahs In Soil By Two Deuteromycete Fungi
Author: Clemente A.R.

Abstract: The fungal strains used is this work, namely, 984 and 1040, were isolated fr om soil samples collected at the Jureia-Itatins Ecological Reserve, São Paulo-Brazil. Following microscopical examinations these strains were classified as Aspergillus sp. (984) and Verticillium sp. (1040). The degradation of PAHs in soil contaminated with 5 mg naphthalene/g soil; 1,0 mg anthracene/g soil or 0,5 mg pyrene and/or benzo[a]pyrene/g soil, was verified. These strains were grown in wheatbran:water for 3 days, inoculated in sterilized and non-sterilized soil, and cultivated for 2,4, 6, and 8 weeks. The PAHs were then extracted and degradation was determined by HPLC. The best degradation, in sterilized soil was obtained after 8 weeks for the two strains: naphthalene (64.50-65.43%), anthracene (77.35-85.83%) and pyrene (73.01-78.78%). When benzo[a]pyrene was used the best degradation shown by strain 984 was 89.62% in six weeks and 78.06% by strain 1040 in eight weeks. In non-sterilized soil the strains exhibited lower growth and degradation than in sterilized soil, with the exception for benzo[a]pyrene (82.3-82.6%). Our results indicate that these two fungal strains have potential for application in the bioremediation of soils contaminated with PAHs. © 2005 Springer Science + Business Media, Inc.
