“…They reduce the chlorophyll content in the leaves [ 33 ], interfere with the photosynthesis process [ 34 ], and can bind covalently to proteins, DNA, and RNA, thus disrupting the growth, metabolism, and enzymatic activity of plant cells [ 19 ]. For this reason, it is important to search for methods that will reduce the adverse impact of petrol on the soil properties and enable the efficient and cost-effective remediation of contaminated soils [ 35 , 36 , 37 ].…”

The global use of petroleum hydrocarbons as raw materials and an energy source in industry results in serious environmental, health, and ecological problems. Consequently, there is growing interest in the development of technologies for the rehabilitation of contaminated areas. This study was undertaken in order to determine the effect of different phytostabilising materials (compost, bentonite, and CaO) on the trace element content in soil contaminated with unleaded petroleum 95 (0, 2.5, 5, and 10 cm3 kg−1 of soil). The doses of petroleum applied to the soil were based on the previously conducted preliminary experiment. The highest petroleum dose (10 cm3 kg−1 of soil) significantly reduced the chromium, zinc, and cobalt contents in the soil. Petroleum increased the cadmium, lead, nickel, and copper contents in the soil. The materials used for phytostabilisation (compost, bentonite, calcium oxide) had a significant effect on the trace element content in the soil. The application of mineral materials (bentonite and calcium oxide) was more effective than the application of compost, compared to the control series (without soil amendments) as they reduced the contents of cadmium, chromium, nickel, and cobalt in the soil to the greatest extent. The reduction effect of bentonite and calcium oxide on the content of these trace elements in the soil was stronger than compost.

“…The intensification of industrialization, population growth, and routine human activities has led to an increased demand for secure and cheaper energy source like petroleum hydrocarbon or crude oil, a high carbon polluting source to several media [24,25]. Pollution, in its essence, represents the inadvertent introduction of harmful and unwanted toxic substances into the environment.…”

This chapter focuses on the estimation of parameter affinity in rhizobacterial cocktail formulations for bio-recovery of crude oil-impacted soil. The topic relied on a study investigating the utilization of locally available substrates in ecologically disturbed ecosystems, with a focus on the rhizosphere of weeds growing on aged crude oil-impacted soil in the Niger Delta region. The identified rhizobacterial isolates: Achromobacter agilis, Pseudomonas fluorescens, Bacillus thuringiensis, and Staphylococcus lentus, are renowned for significant biodegradative potentials. The researchers assessed the impact of different parameters on growth dynamics of these isolates. By utilizing agro-residues like corn chaff as carbon source, corn steep liquor for nitrogen, and poultry droppings for phosphorus, as sources of limiting nutrients, the researchers varied factors like nutrient availability, pH levels, and temperature to estimate the affinity of these parameters for growth formulations and bioremediation capabilities by fitting the substrate utilization data into a Growth Kinetics Models. Data obtained revealed the isolates’ affinity for different substrates and provide valuable insights for optimizing the composition and performance of rhizobacterial cocktails for efficient hydrocarbon degradation in crude oil-impacted soil. Additionally, they underscored the potential of locally available substrates and microbial flora as effective tools for bio-recovery of crude oil-impacted soil.

“…The microbial population is significantly higher in the soil, as it offers a feasible environment for the growth of the microbes. [ 28 ] However, the soil is mostly heterogeneous in terms of physical and chemical properties, as well as microbiological compositions. This heterogeneous nature of the soil leads to corrosion of the unprotected buried pipelines at various locations.…”

Microbially induced corrosion (MIC) damage in crude oil and natural gas‐bearing pipelines is a severe threat for the petroleum industries. This is primarily due to the presence of hydrocarbons, which serve as nutrients for microorganisms. The comfortable growth of these microorganisms in hydrocarbon systems ultimately results in enhanced degradation of the pipelines. Hence, to understand the effect of microorganisms on the degradation of petroleum hydrocarbons and its subsequent influence on the corrosion of pipeline materials, a detailed review of the literature has been carried out. This review is primarily focused on the principal factors and the major microorganisms responsible for biofilm development. Furthermore, the role of these microorganisms in causing MIC in underground buried petroleum‐bearing pipelines has been reviewed in detail. Most importantly, the techniques required for studying MIC have been thoroughly discussed. In addition, a few microbial cases associated with various petroleum industries have been reviewed to acquire a clear understanding about the real situation.
