Abstract The aim of this work was to isolate indigenous PAH degrading-fungi from petroleum contaminated soil and exogenous ligninolytic strains from decaying-wood, with the ability to secrete diverse enzyme activity. A total of ten ligninolytic fungal isolates and two native strains, has been successfully isolated, screened and identified. The phylogenetic analysis revealed that the indigenous fungi (KBR1 and KB8) belong to the genus Aspergillus niger and tubingensis. While the ligninolytic exogenous PAH-degrading strains namely KBR1-1, KB4, KB2 and LB3 were affiliated to different genera like Syncephalastrum sp, Paecilomyces formosus, Fusarium chlamydosporum, and Coniochaeta sp., respectively. Basis on the taxonomic analysis, enzymatic activities and the hydrocarbons removal rates, single fungal culture employing the strain LB3, KB4, KBR1 and the mixed culture (LB3+KB4) were selected to be used in soil microcosms treatments. The Total petroleum hydrocarbons (TPH), fungal growth rates, BOD5/COD ratios and GC-MS analysis, were determined in all soil microcosmos treatments (SMT) and compared with those of the control (SMU). After 60 days of culture incubation, the highest rate of TPH degradation was recorded in SMT[KB4] by approximately 92±2.35% followed by SMT[KBR1] then SMT[LB3+KB4] with 86.66±1.83% and 85.14±2.21%, respectively.

This study aims to use contaminated soil with leachate to select autochthonous fungi that are able to bioremediate three types of leachate, (Young (YL), Intermediate (IL) and Old (OL)). Eleven fungal species were isolated via the enrichment method using the leachate as the sole source of carbon and energy. The isolates were evaluated for their ability to grow and remove organic pollutants at 100%, 50% and 25% (v/v) of leachate in both solid and liquid cultures that were spiked with malt extract. The results indicated that only three fungi, <i>Aspergillus flavus</i> (<i>A. flavus</i>-LC106118), <i>Aspergillus niger</i> (<i>A. niger</i>-KT192262) and <i>Fusarium solani</i> (<i>F. solani</i>-KX349467) showed significantly high capacity to grow on leachate, with maximum radial growth rates (Gr) of 7.5 mm, 4.7 mm , and 5.3 mm, respectively. In addition, 34%, 22%, and 27%, respectively of COD removal rates were obtained at 25% concentration in YL. A. flavus was the most tolerant fungus against landfill leachate, followed by <i>F. solani</i>, and finally <i>A. niger</i>. Therefore, these three fungi are good candidates for leachate bioremediation. However, for a better remediation, the combined effects of different types of fungi and leachates on the fungal growth need to be considered during the fungi selection.

Abstract A description is provided for Fusarium oxysporum f. sp. pisi. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Pisum sativum L. (pea). Also reported to cause wilting of Dianthus spp. (74, 4545). DISEASE: Fusarium wilt, near wilt. Also a component in St. John's disease together with Fusarium solani (Martius) Sacc. (Buxton, 1955). GEOGRAPHICAL DISTRIBUTION: Widespread where peas are cultivated. TRANSMISSION: Contaminated seed. Movement of contaminated soil during cultivation. Local dispersal may occur via water flow and splash droplets containing micro- or macroconidia.
