“…The susceptibility of hydrocarbons to be degraded by microorganisms (linear alkanes > branched alkanes > small aromatic compounds > cyclic alkanes > polycyclic aromatic hydrocarbons) is one of the limiting factor for biodegradation. Soil fungi have been reported with efficiency of biodegradation of 6% to 82% while soil bacteria [2] and marine have biodegradation efficiency of 0.13-50% and 0.003-100% respectively [3]. The fungal oxidation of hydrocarbon compounds employees' monooxygenase enzyme that leads to formation of trans-diol.…”

“…Fungal soil remediation is still less studied than bacterial hydrocarbon degradation processes [10]. Fungi might be more advantageous over bacteria in the remediation process as they do not depend on merely soluble, readily absorbed organic compounds for nutrition [11]. The use of fungi for air biofiltration has also been investigated in recent years [12].…”

Naturally occurring microorganisms in soil matrices play a significant role in overall hydrocarbon contaminant removal. Bacterial and fungal degradation processes are major contributors to aerobic remediation of surface contaminants. This study investigated degradation of conventional diesel, heating diesel fuel, synthetic diesel (Syntroleum), fish biodiesel and a 20% biodiesel/diesel blend by naturally present microbial communities in laboratory microcosms under favorable environmental conditions. Visible fungal remediation was observed with Syntroleum and fish biodiesel contaminated samples, which also showed the highest total hydrocarbon mineralization (>48%) during the first 28 days of the experiment. Heating diesel and conventional diesel fuels showed the lowest total hydrocarbon mineralization with 18–23% under favorable conditions. In concurrent experiments with growth of fungi suspended on a grid in the air space above a specific fuel with little or no soil, fungi were able to survive and grow solely on volatile hydrocarbon compounds as a carbon source. These setups involved negligible bacterial degradation for all five investigated fuel types. Fungal species able to grow on specific hydrocarbon substrates were identified as belonging to the genera of Giberella, Mortierella, Fusarium, Trichoderma, and Penicillium.

“…Yet these techniques have not been utilised commercially in many tropical regions. Dickson et al (2019) reported that for optimal utilisation of these techniques, ideal conditions for their applications should be investigated. There are several reports on remediation potential of sunflowers (Dominguez-Rosado et al, 2004;Diab, 2008).…”

“…This information is important in the choice of the agents among their numerous species. Adapting P. ostreatus for use in the clean-up of petroleum-contaminated soils has been problematic (Stamet, 2005;Dickson et al, 2019). The present study also seeks to develop a realistic approach and investigate a novel substrate (Palm tree which is abundant in tropical regions) for application of P. ostreatus in the clean-up of petroleum-contaminated soils.…”

Phyto-and myco-remediation have been identified as sustainable options for treatment of petroleumcontaminated soils. To appraise the benefits thereof, the potentials of 3 sunflower species, 2 palm wine types and P. ostreatus to treat petroleum-contaminated soils was investigated. The study involved sampling of petroleum-contaminated soils and treatment with the phyto-and myco-remediation agents for a period of 90days. Agents used for the remediation were 3 species of sunflowers (Helianthus annus-pacino gold, Helianthus sunsation & Helianthus annus-sunny dwarf), fermented palm wine (from 2 species of palm trees-Elaeis guineensis & Raffia africana), and oyster mushroom (Pleurotus ostreatus). The study further investigated variation in remediation efficiency among the sunflower and palm wine species, as well as different substrates and conditions for optimal application of P. ostreatus. The results obtained revealed up to 340 g/kg dry weight of Total petroleum hydrocarbons (TPHs) in the soils, with remediation outcomes of up to 69% by the sunflower-Helianthus annus (Pacino gold), 70% by fermented palm wine, and 85% by P. ostreatus. While the remediation efficiency of sunflower species was proportional to biomass, there was no significant difference in remediation efficiency of the palm wines. It was also found that substrates type and method of application has a significant impact on the remediation efficiency of P. ostreatus. The study further revealed available nitrate and electrical conductivity as possible useful indicators of TPHs concentration and remediation progress in soils.
