“…The soil pH of the two samples (Polluted marshland and terrestrial) sites were within the same range, and they were tending from slightly acidic towards neutrality. This result concord with the observation of [34,35], who indicated that a pH between 5 and 7.8 is favourable for the biodegradation activity of bacteria in the soil. [36] reported similar results on pH of crude oil polluted soils of Niger Delta.…”

Aim: To investigate bioremediation potentiality of Pseudomonas aeruginosa KX828570 on crude oil Polluted Marshland and Terrestrial Soil treated with oil spill dispersant Study Design: The study employs experimental design, statistical analysis of data and interpretation. Place and Duration of the Study: Soil samples were collected from K-Dere, Gokana L.G.A, and were transported to the Microbiology Laboratory of Rivers State University, Port Harcourt, Nigeria for analyses while Oil spill dispersant (OSD/LT and OSD/Seacare) were from Barker and Hughes Nig Ltd (formally mil park Nigeria limited), all in Rivers state, Nigeria. This investigation study lasted for 28 days and sampling was done every 7day period. Methodology: Eight experimental set up were carried out using Pseudomonas aeruginosa KX828570 as the bio-augmenting organism in terrestrial and marshland soil contaminated with two Oil spill dispersant (OSD/LT and OSD/Seacare) separately. Controls for the two soil types were made without organism and treatment. Its bioremediation potential on the pollutants and two types of soil were monitored for 28 days. The setup was tilled twice a week to provide moisture and more oxygen for the organisms to thrive. Analysis of pH, Temperature, Moisture content, Total Hydrocarbon Content, Total Heterotrophic Bacteria, Dispersant Utilizing Bacteria was carried out at weekly intervals. Results: The pH of both soils ranged from 5.75 to 7.37; temperature from 270C to 340C; moisture content 03 to 0.6 across the soil samples. Total Hydrocarbon Content (THC) showed a steady decline from day 1 – 28. The percentage (%) bioremediation rates of polluted soils were as follows: Terrestrial soil+OSD/Seacare+Pseudomonas aeruginosa KX828570 69.4% > Terrestrial soil+OSD/LT+ Pseudomonas aeruginosa KX828570 65.9% > Marshland soil+OSD/Seacare+ Pseudomonas aeruginosa KX828570 52.6% > Marshland soil+OSD/Seacare+ Pseudomonas aeruginosa KX828570 47.6%. Dispersant utilizing bacterial count in marshland and terrestrial soil ranged from 6.013 to 7.338 log10Cfu/g and 6.045 to 7.301 log10Cfu/g respectively from Day 1 to 28. Conclusion: From the investigation, it revealed that Oil spill dispersants are more degradable in terrestrial soil than marshland soil. OSD/Seacare is more biodegradable than OSD/LT in both terrestrial and marshland soil augmented with Pseudomonas aeruginosa KX828570. Thus, Pseudomonas aeruginosa KX828570 have been found to be a potential bioremediation agent in oil spill dispersant polluted marshland and terrestrial soil.

“…Benka-Coker and Ekundayo (1995) and Abii and Nwosu (2009) reported high TOC contents in crude oil impacted soil of Niger Delta area. The weakly acidic pH result shows that crude oil spill has no significant effect on soil pH of the area as similar result was also reported by Tanee and Albert (2011) and Gighi et al (2012).…”

“…Soil total exchangeable cations (i.e. Mg ) result correspond with Tanee and Albert (2011). The low values recorded in the study site may be attributed to leaching of the cations due to the high precipitation of the Niger-Delta ecozone (Kinako et al, 1993).…”

Long-term effects on soil chemical properties and plant composition of a crude oil polluted site were assessed using random surface soil samples and quantitative vegetation data collection methods. Results showed that total hydrocarbon content (542.50±28.58 mg kgG 1 ) and total organic carbon (1.06±0.18%) of polluted site were significantly (p = 0.05) higher than the unpolluted site of 27.90±22.10 mg kgG 1 and 0.73±0.06%, respectively. Plant species composition showed that Aspillia busei and Heterotis rotundofolia were abundant at polluted site and absent in unpolluted site while Panicum maximum and chromolaena odoratum were absent in polluted site. Species diversities records were 0.37 (polluted site) and 0.64 (unpolluted). Aspillia busei recorded the highest frequency of occurrence (90%) and density (28.2 mG 2 ) in the polluted site while Starchytarpheta jamaicensis recorded the highest frequency of occurrence (40%) and Andropogon tectorum the highest density (3.9 mG 2 ) at the unpolluted site. It can be concluded that the effects of crude oil pollution persists for a long time and negatively affect soil chemical properties, plant species composition and species diversity.

“…These pH values were in the acid to near-neutral range, which is a typical characteristic of soils of the Niger Delta (Iwegbue et al 2012;Iwegbue 2014). The percentages of total nitrogen (TN) in the soils were generally low, while the TOC contents of the soils were close to the range for Niger Delta soils (Tanee and Albert 2011). The swamp forest soil had a higher TOC content than the fadama soil (Table 1).…”

Purpose This study sought to investigate the effects of organic amendments on the degradation of hydrocarbons and vegetative properties of Zea mays grown in crude oil-contaminated wetland soils of the Niger Delta, Nigeria. Methods Two soil types were investigated, namely, fadama soil (oxisol) and swamp forest soil (utisol). For each soil type, 48 treatment cells and 1 control containing 1 kg of soil each were spiked with crude oil at concentrations ranging from 50 to 200 g kg −1 , representing 5-20% (m/m) contamination levels, respectively. Then, 5 days after the contamination, the soils were amended with cow dung (CD), poultry waste (PW), and palm oil waste (POW). The ratios of soil to organic amendments used were 1:1 and 2:1. The soils were tilled and irrigated regularly, and monitored for a total period of 112 days. The same conditions were used to investigate the vegetative properties of Z. mays in these oil-contaminated soils with organic amendments.Results The total organic carbon (TOC) and pH increased significantly within the first 2 weeks after crude oil contamination; thereafter, the pH of the soil decreased significantly over incubation time, while there was steady increase in TOC with incubation time. The percentage nitrogen and total petroleum hydrocarbons (TPH) decreased significantly. The utisol soil showed better plant performance, despite the lower hydrocarbon degradation rate. Conclusion The organic amendments showed a TPH degradation trend that followed the order: PW > CD > POW. They also improved the seed emergence of Zea mays.
