“…Crude oil polluted soil amended with organic matter may stimulate growth of the indigenous oil degrading microbiota in it [18]. Similar observations have been reported using organic amendment [52]. By the end of the study, population of indigenous oil degrading microbiota increased rapidly, which corresponds to high availability of hydrocarbons during these periods [53].…”

The biostimulation potentials of carrot peel waste and carob kibbles for bioremediation of crude petroleum-oil polluted soil were investigated. Temperature, pH, moisture, total petroleum hydrocarbon (TPH), and changes in microbial counts during 45 days were monitored when 4 mL of carrot peel waste or carob kibbles media were added to 200 g of crude oil polluted soil samples. Gas chromatography-flame ionization detection (GC-FID) was used to compare hydrocarbon present in the crude oil polluted soil and in pure fuel, composition of crude oil polluted soil was analyzed by X-ray diffraction (XRD), and the TPH was measured by distillation using distiller mud. The results showed that, at the end of experiments, the concentration of TPH decreased in crude oil polluted soil containing carrot peel waste with a percentage of 27 ± 1.90% followed by crude oil polluted soil containing carob kibbles (34 ± 1.80%) and in the unamended control soil (36 ± 1.27%), respectively. The log [Colony Forming Unit (CFU)/g] of total heterotrophic bacteria in the crude oil polluted soil increased from 10.46 ± 0.91 to 13.26 ± 0.84 for carrot peel waste, from 11.01 ± 0.56 to 11.99 ± 0.77 for carob kibbles and from 8.18 ± 0.39 to 8.84 ± 0.84 for control, respectively. Such results demonstrated that carrot peel could be used to enhance activities of the microbial hydrocarbon-degrading bacteria during bioremediation of crude petroleum-oil polluted soil.

Background and Objective: Crude oil pollution is a serious issue in Nigeria. There is, therefore, a need to source an affordable method that is eco-friendly for remediating these polluted soils. The study investigated the use of cassava peel waste as a bio stimulating agent in an in situ bioremediation of crude oil polluted site. Materials and Methods: Treatments were as follows, H 1 : Polluted soil with no bio-stimulation (Control), H 2 : Polluted soil bio-stimulated with 500 g cassava peel, H 3 : Polluted soil bio-stimulated with 1000 g cassava peel and H 4 : No pollution, no bio-stimulation (double control). Soil pH, electrical conductivity, moisture content, nitrogen, phosphorus, total organic matter, total organic carbon, potassium, total petroleum hydrocarbon, total hydrocarbon content and microbial population in soil were monitored at 0, 2 and 4 months. Results: Results showed that the percentage reduction of THC and TPH in the soil after 4 months were as follows, H 2 (90.48 and 81.39%), H 3 (80.19 and 63.81%) and H 1 (32.90 and 14.76%), respectively. Soil properties improved with a concurrent increase in the microbial population in the bio-stimulated soil as compared to the control. Conclusion: This result proves that cassava peel waste is an effective bio-stimulating agent in crude oil degradation especially at 500 g m 3 compared to other treatment options hence providing an alternative for the remediation of crude oil-polluted soil, especially in the Niger Delta part of Nigeria.

As one of the most important components of the lake ecosystem, microorganisms from the freshwater and sediment play an important role in many ecological processes. However, the difference and correlation of bacterial community between these two niches were not clear. This study investigated the diversity of microbial community of freshwater and sediment samples from fifteen locations in Poyang Lake wetland. The correlation between the bacterial community and physicochemical property of Poyang Lake wetland was analyzed by artificial neural network (ANN). Our results demonstrated that the freshwater and sediment bacterial community were dominated by groups of the Bacteroidetes (23.33%) and β-Proteobacteria (22.54%) separately, whereas, Canalipalpata, Bacillariophyta, Gemmatimonadetes, and Verrucomicrobia were detected in freshwater niches only. Phylogenetic analysis further indicated that bacterial composition in freshwater significantly differed with the sediment niches. There are 34 unique species accounted for 85% in fresh water samples and 28 unique species accounted for 82% in sediment samples. Cluster analysis further proved that all the samples from freshwater niches clustered closely together, far from the rest sediment samples. ANN analysis revealed that the freshwater with high N and P nutrients will greatly increase the diversity of the bacterial communities. In general, both environmental physicochemical properties, not each factor independently, contributed to the shift in the bacterial community structure. The five tributaries (Gan, Fu, Xin, Rao, Xiu Rivers) play a vital role in shaping the bacterial communities of Poyang Lake. This study provides new insights for understanding of microbial community compositions and structures of Poyang Lake wetland.
