RESEARCH ARTICLE Degradation of Bunker C Fuel Oil by White- Rot Fungi in Sawdust Cultures Suggests Potential AppliCations in Bioremediation
2016Co-Authors: Darcy Young, James Rice, Rachael Martin, Erika Lindquist, Anna Lipzen, Igor Grigoriev, David HibbettAbstract:Fungal lignoCellulolytiC enzymes are promising agents for oxidizing pollutants. This study investigated degradation of Number 6 “Bunker C ” fuel Oil Compounds by the white-rot fungi Irpex laCteus, TriChaptum biforme, Phlebia radiata, Trametes versiColor, and Pleurotus ostreatus (BasidiomyCota, AgariComyCetes). Averaging aCross all studied speCies, 98.1%, 48.6%, and 76.4 % of the initial Bunker C C10 alkane, C14 alkane, and phenanthrene, respeCtively were degraded after 180 days of fungal growth on pine media. This study also investigated whether Bunker C Oil induCes Changes in gene expression in the white-rot fun-gus PunCtularia strigosozonata, for whiCh a Complete referenCe genome is available. After 20 days of growth, a monokaryon P. strigosozonata strain degraded 99 % of the initial C10 alkane in both pine and aspen media but did not affeCt the amounts of the C14 alkane or phenanthrene. Differential gene expression analysis identified 119 genes with log2(2-fold) greater expression in one or more treatment Comparisons. Six genes were signifiCantly upregulated in media Containing Oil; these genes inCluded three enzymes with potential roles in xenobiotiC biotransformation. Carbohydrate metabolism genes showing differential expression signifiCantly aCCumulated transCripts on aspen vs. pine substrates, perhaps refleCting white-rot adaptations to growth on hardwood substrates. The meChanisms by whiCh P. strigosozonatamay degrade Complex Oil Compounds remain obsCure, but degra-dation results of the 180-day Cultures suggest that diverse white-rot fungi have promise for bioremediation of petroleum fuels

Gladstone, Australia Field Studies: Weathering and Degradation of HydroCarbons in Oiled Mangrove and Salt Marsh Sediments With and Without the AppliCation of an Experimental Bioremediation ProtoCol
Marine Pollution Bulletin, 2000Co-Authors: Kathryn A. Burns, Susan Codi, Norman C. DukeAbstract:This field study was a Combined ChemiCal and biologiCal investigation of the relative rates of weathering and biodegradation of Oil spilled in sediments and testing the influenCe of a bioremediation protoCol. The aim of the Chemistry work presented here was to determine whether the bioremediation protoCol affeCted the rate of penetration, dissipation or long-term retention of a medium range Crude Oil (Gippsland) and a Bunker C Oil stranded in tropiCal Rhizophora sp. mangrove and HalosarCia sp. salt marsh environments. Permission for the planned Oil spills was granted in the Port Authority area of Gladstone, Queensland (Australia). Sediment Cores from three repliCate plots of eaCh treatment for mangroves and four repliCate plots for the salt marsh (Oil only and Oil plus bioremediation) were analysed for total hydroCarbons (THC) and for individual alkane markers using gas Chromatography with flame ionization deteCtion (GC-FID). Sediments were ColleCted at day 2, then 1, 2, 5 or 6 and 12 or 13 months post-spill for mangroves and day 2, 1, 3 and 9 months post-spill for salt marshes. Over this time, hydroCarbons in all of the Oil treated plots deCreased exponentially, There was no statistiCal differenCe in initial Oil ConCentrations, penetration of Oil to depth, or in the rates of Oil dissipation between untreated Oil and bioremediated Oil in the mangrove plots. The salt marsh plots treated with the waxy Gippsland Oil showed a faster rate of biodegradation of the Oil in the bioremediated plots. In this Case only, the degradation rate signifiCantly impaCted the mass balanCe of remaining Oil. The Bunker C Oil Contained only minor amounts of highly degradable il-alkanes and bioremediation did not signifiCantly impaCt its rate of loss in the salt marsh sediments, At the end of eaCh experiment, there were still n-alkanes visible in the gas Chromatograms of residual Oils. Thus it was ConCluded that there was unlikely to be any Change in the stable internal biomarkers of the Oils over this time period. The predominant removal proCesses in both habitats were evaporation and dissolution, with a lag-phase of 1-2 months before the start of miCrobial degradation. (C) 2000 Elsevier SCienCe Ltd.
