Abstract |
: |
The present study focuses on fungal strains capable of secreting extracellular enzymes by utilizing
hydrocarbons present in the contaminated soil. Fungal strains were enriched from petroleum hydrocarbons
contaminated soil samples collected from Chennai city, India. The potential fungi were isolated and
screened for their enzyme secretion such as lipase, laccase, peroxidase and protease and also evaluated
fungal enzyme mediated PAHs degradation. Total, 21 potential PAHs degrading fungi were isolated from
PAHs contaminated soil, which belongs to 9 genera such as Aspergillus, Curvularia, Drechslera, Fusarium,
Lasiodiplodia, Mucor, Penicillium, Rhizopus, Trichoderma, and two oilseed-associated fungal genera such
as Colletotrichum and Lasiodiplodia were used to test their efficacy in degradation of PAHs in polluted soil.
Maximum lipase production was obtained with P. chrysogenum, M. racemosus and L. theobromae VBE1
under optimized cultural condition, which utilized PAHs in contaminated soil as sole carbon source.
Fungal strains, P. chrysogenum, M. racemosus and L. theobromae VBE1, as consortia, used in the present
study were capable of degrading branched alkane isoprenoids such as pristine (C17) and pyrene (C18)
present in PAHs contaminated soil with high lipase production. The fungal consortia acts as potential
candidate for bioremediation of PAHs contaminated environments. |
