“…Untreated wastewater is used for irrigation of about 26% of the vegetables grown in Pakistan [ 1 ]. Metal contamination is a noteworthy issue because of its antagonistic impact on soil richness and plant development, and it also triggers negative physiological and metabolic changes in plants [ 2 ]. Heavy metals, after gaining entry into the plants via different transporters, bind to specific sites on membrane lipids and proteins, resulting in conformational changes.…”

This research was carried out to evaluate the effect of biochar and compost application on Spinacia oleracea growth in cadmium contaminated soil. Cd toxicity decreased plant growth and biomass significantly and also negatively affected the physiological and biochemical attributes of plants. However, the application of biochar and compost improved the contaminated soil by reducing Cd toxicity and causing its immobilization, which in turn improved plant growth. The combined application of biochar and compost significantly (p < 0.05) enhanced biomass and photosynthetic pigments development in plants. The treatments also increased membrane stability index by 45.12% and enhanced water using efficiency by 218.22%, respectively. The increase in antioxidant activities was 76.03%, 29.02%, and 123.27% in superoxide dismutase, peroxidase, and catalase, respectively. The combined application also reduced the cadmium content (reduced 40.14% in root and 51.16% shoot), its translocation (19.67% decrease), and bioaccumulation (52.63% and 40.32% decrease in Cd content in shoot and root, respectively) in spinach plant. Among the two selected varieties of S. oleracea, Desi palak (V1) performed better as compared to Kanta palak (V2). It can be concluded that the combined application of biochar and compost is one of the best strategies to reduce the toxicity level of Cd in plants and to improve their growth.

“…Contamination of soil is prominent among the most critical environmental issues throughout the world, and it has a hugely harmful impact on people, animals, microorganisms, and plants [1]. Correspondingly, heavy metals pollute the earth and have injurious impacts on the environment and its sectors [1]. Activities in the over half a century operations in the oil and gas industry in Nigeria have resulted in unprecedented release of hydrocarbons and associated pollutants including heavy metals into the Niger Delta environment from refine and unrefined petroleum products [2,3].…”

In this research, the soil samples were contaminated with 0.05% and 0.1% of cadmium and lead. Seventy pots containing 200 g of soil were polluted with 5% diesel (w/w) (10 g). The physicochemical parameters of the soil were determined. There was a decrease in the pH, and electrical conductivity but the nitrogen, phosphorous, organic carbon and organic matter increased during the 84 days of biodegradation. The bacteria isolated from diesel oil contaminated soil were species of Bacillus and Pseudomonas. The GC-MS analysis revealed a significant decrease in the alkane and an increase in the ester constituents of the biodegraded oil samples after 84 days. Diesel oil co-contaminated soil supplemented with 0.1% of cadmium and lead had a percentage degradation of 89.5% and 80.54% respectively while compared to the un-supplemented samples (28.36%) after 84 days. This indicates that lead and cadmium as co-contaminant in diesel contaminated soil improved the rate of biodegradation of diesel.

The herbicides, used to fight against the weeds in the agriculture are very toxic to soil biota.…”

This study was aimed at isolating Pseudomonas aeruginosa from the soil to produce biosurfactant for degradation of herbicide. The soil sample was collected from oil polluted site in mechanic workshop, Minna, Niger State, Nigeria and transferred to the microbiology laboratory of the University in a sterile polyethylene bag. Pseudomonas aeruginosa was isolated from the soil and identified using microbiological and biochemical assays. The isolate was screened for biosurfactant production using haemolytic assay, drop collapse, oil spreading and emulsification test. Biosurfactant production was carried out using mineral salt medium for ten days. The ability of the biosurfactant produced by P. aeruginosa in degrading herbicide was tested on five concentrations of herbicide (5%, 10%, 30%, 50%, 70%) and the results showed biodegradation percentages as 56.4%, 53.1%, 32.6%, 29.8% and 26.2% respectively revealing that degradation was higher at lower concentrations. This suggests that herbicide could be biodegraded especially at low concentrations using biosurfactant produced by Pseudomonas aeruginosa.Contribution/Originality: The paper's primary contribution is finding that biosurfactant could be produced from bacteria (Pseudomonas aeruginosa) and this could be used for degradation of herbicide that has remained an environmental problem.
