Effect of Triton X-100 and White Rot Fungus (Pleurotus ostratus) on Physico-chemical Composition of Crude Oil Impacted Soil

Abstract

The study investigated the effect of triton x-100 and white rot fungus (Pleurotus ostratus) on physico-chemical composition of crude oil impacted soil. Crude oil highly impacted soil excavated from an oil spill site at Obeche community in Ogba/Egbema/Ndoni Local Government Area of Rivers State, Nigeria was used in this study. Remediation was induced by biostimulation using white rot fungus (Pleurotus ostreatus) and treatment with a chemical surfactant (Triton x-100). The pH value of polluted soil sample (Cell A) was high (6.81± 0.52) when compared with other cells that were amended. The result of the soil electrical conductivity shows a significant difference (p≤ 0.05) when cell A is compared with other cells. Only cell C amended with Triton x-100 had a lower value of 31.67 ± 1.52 when compared with cell A (polluted soil sample) (76.67 ± 1.52). Cells B and D had higher values of 161.00 ± 2.00, and 233.67 ± 4.04 respectively when compared with cell A (76.67 ± 1.52). Significant (p≤0.05) increase in the total organic carbon (TOC) and total nitrogen (TN) contents was observed amended cells after the 60 days period of incubation when compared with cell A. For PO 4 3-(mg/kg) and NO-3 (mg/kg) all the cells were significantly different (p≤ 0.05) Original Research Article

Influence of Water Insoluble Fractions of Crude Oil on Physicochemical Properties and Microbes of Soil Obtained From a Tertiary Institution in Benin City, Nigeria

“…Curylo et al, (2020), have reported similar results; significant changes were seen in soil organic compound, nitrogen content and phosphatases. A good number of research have also reported similar findings on the effect of crude oil on soil THC, pH and nitrate (Anacletus et al, 2017, Pathak et al, 2011, Hassan et al, 2018. This again confirms the result of this research, although the previous research studied the effect of whole crude, which was seen to have very similar effect with WIF that was investigated in this research.…”

Influence of Mycoremediation and Selected Surfactants on Growth Performance of Fluted Pumpkin In Crude Oil Impacted Soil and the Nephrotoxic Effects of Leaves Aqueous Extract on Wistar Rats

“…Petroleum has continuously grown to be the mainstay of the Nigerian economy. However, the exploration of petroleum has led to the pollution of land and waterways [2].…”

“…The exploration of petroleum products has rendered agricultural lands less productive [7,2], and the creeks and the aquatic lives have become more or less dead [8, 9,2]. The primary mechanism for eliminating spilled oil from the environment is the microbial degradation [10].…”
