“…The results from our study showed significant reduction in the level of used motor oil contamination in the potato skin-amended soil In the present study, potato skin had higher nitrogen content than the experimental soil (Table 1). Nitrogen and phosphorus have been reported as essential nutrients for bioremediation of petroleum hydrocarbons in the soil [19]. In other words, as bioremediation progresses in the absence of external nutrient sources such as nitrogen, carbon, phosphorus etc., the microorganisms will utilize available nutrients in the soil to a point of depletion and the nutrients becomes limiting.…”

The potential of potato skin (PS) to enhance bioremediation of soil polluted with used motor oil was investigated gravimetrically for a period of 42 days. Polluted soil was amended with 5%, 10% and 15% (w/w) of PS. Loss of total petroleum hydrocarbon (TPH), microbial growth and germination indices were all investigated throughout the study period. At the end of 42 days, there was significant oil loss of 73.85% in the amended soil. Hydrocarbon-utilizing bacterial (HUB) counts were significantly higher(P≤0.05) in the amended option ranging from 6.7 x 10 6 to 22.3 x 10 6 CFU/g. The HUB isolated from the oil-contaminated soil were identified tentatively as belonging to the genera: Bacillus, Arthrobacter, Rhodococcus, Corynebacterium, Pseudomonas, Staphylococcus and Acinetobacter. Similarly, fungal counts ranged from 4.8 x 10 5 to 59.0 x 10 5 CFU/g. Aerobic fungi isolated were identified tentatively as Aspergillus niger, Aspergillus sp., Pennicillum sp., Phialophora sp., Cladosporium sp. and Verticillum sp. Germination index of 69.46% was recorded in the amended option. Oil loss and microbial growth were significantly higher (P≤ 0.05) in the amended option than the control option. Potato skin, therefore can offer a good alternative in bioremediation of soil polluted with used motor oil.

Bioaccumulation for heavy metal removal: a review

et al. 2023

View full text Add to dashboard Cite

This paper reviews plants and microorganisms removal of heavy metals from contaminated sites through bioaccumulation. Increased industrial activities have led to the uncontrolled release of metals into the environment, resulting in a global increase in metal pollution. Heavy metals are also consumed from the surface of glasses over a prolonged period of use. Heavy metal pollution is a serious problem that can have wide-ranging and long-lasting impacts on human health and the environment. Therefore, effective removal and remediation of heavy metal pollution are crucial to protect human and ecological health. Traditional methods of heavy metal removal, such as chemical treatment and physical removal, can be costly and can also have negative impacts on the environment. The utilization of plants and microorganisms for bioremediation of metal-polluted environments has proven effective for removing metals through accumulation and/or detoxification. This method is effective, economical, versatile, and environmentally friendly. Bioaccumulation utilizes plants and microorganisms to absorb and remove heavy metals from contaminated sites. This method is not only cost-effective but also helps to minimize the environmental impact of heavy metal pollution. Additionally, bioaccumulation can be used in combination with other techniques, such as phytostabilization and phytodegradation, to further improve the efficiency of heavy metal removal. The paper also discusses the use of plants and microorganisms in the removal of heavy metals from water and soil through biomagnification and bioconcentration. Techniques such as phytoaccumulation, phytostimulation, phytodegradation, phytovolatilization, phytostabilization, and phytofiltration are also discussed as effective ways of remediation of heavy metal contaminated sites.
