Petroleum Hydrocarbon Bioremediation Using Native Fungal Isolates and Consortia

Table 4

Changes in the mixture of PAHs (mg/l), estimated by HPLC, for samples treated with three fungal consortia corresponding to untreated control. FC1 = mixed culture of Penicillium chrysogenum and Curvularia brachyspora, FC2 = mixed culture of Scopulariopsis brevicaulis and Stemphylium botryosum, and FC3 = mixed culture of Scopulariopsis brevicaulis, Stemphylium botryosum, and Cladosporium sphaerospermum. Nap = naphthalene, A = acenaphthylene, Ace = acenaphthene, F= fluorene, Phe = phenanthrene, Ant = anthracene, Flu = fluoranthene, Pyr = pyrene, BaA = benzo (a) anthracene, BaP = benzo (a) pyrene, BbF = benzo (b) fluoranthene, BkF = benzo (k) fluoranthene, Chr = chrysene, DahA = dibenzo (a, h) anthracene, and BP = benzo (g, h, i) perylene.
