“…Most remediation combination methods are designed to enhance the microbial activity and aeration of polluted soil because of the hydrophobicity and fluidity of petroleum. To increase the system's degradation rate, an electric field, fertilizers, biocarrier, biochar, biosurfactants, and plants were applied to the petroleumcontaminated soil [121][122][123]. As shown in Table 2, the combination of microbes and physical or chemical technologies can improve the efficiency of microbial degradation of petroleum pollutants.…”

The petroleum industry’s development has been supported by the demand for petroleum and its by-products. During extraction and transportation, however, oil will leak into the soil, destroying the structure and quality of the soil and even harming the health of plants and humans. Scientists are researching and developing remediation techniques to repair and re-control the afflicted environment due to the health risks and social implications of petroleum hydrocarbon contamination. Remediation of soil contamination produced by petroleum hydrocarbons, on the other hand, is a difficult and time-consuming job. Microbial remediation is a focus for soil remediation because of its convenience of use, lack of secondary contamination, and low cost. This review lists the types and capacities of microorganisms that have been investigated to degrade petroleum hydrocarbons. However, investigations have revealed that a single microbial remediation faces difficulties, such as inconsistent remediation effects and substantial environmental consequences. It is necessary to understand the composition and source of pollutants, the metabolic genes and pathways of microbial degradation of petroleum pollutants, and the internal and external aspects that influence remediation in order to select the optimal remediation treatment strategy. This review compares the degradation abilities of microbial–physical, chemical, and other combination remediation methods, and highlights the degradation capabilities and processes of the greatest microbe-biochar, microbe–nutrition, and microbe–plant technologies. This helps in evaluating and forecasting the chemical behavior of contaminants with both short- and long-term consequences. Although there are integrated remediation strategies for the removal of petroleum hydrocarbons, practical remediation remains difficult. The sources and quantities of petroleum pollutants, as well as their impacts on soil, plants, and humans, are discussed in this article. Following that, the focus shifted to the microbiological technique of degrading petroleum pollutants and the mechanism of the combined microbial method. Finally, the limitations of existing integrated microbiological techniques are highlighted.

“…To prevent a potential mangrove dieback and the release of hydrocarbons into the coastal environment, it is critical to put in place remediation actions and plans to protect and monitor mangroves (Newton et al, 2020;Ossai et al, 2020). Some potential remediation approaches include the use of hydrocarbon-degrading microbial communities (Daccò et al, 2020;Kumar et al, 2019;Machado et al, 2019), the removal and oxidation of contaminated sediments (Iturbe et al, 2004), the introduction of biochar into affected sediments (Mukome et al, 2020), or phytoremediation involving additional mangrove planting combined with hydrocarbondegrading microorganisms (Verâne et al, 2020). Climate change, along with the rising sea level, and increasing intensity of storms are already accelerating the degradation and loss of mangrove ecosystems worldwide (Duke et al, 2017;Zhang et al, 2019) Supplementary Information (appendices)…”

“…In a different study, when peanut shell biochar was applied to the soil, it resulted in a reduction of potentially toxic elements such as Ni, Cd, As, Pb and Cr [ 177 ]. It has been observed that when biochar is combined with fertilizers, it shows a good remediation potential for soil contaminated with crude oil [ 178 ]. A recent study resulted in increased microbial activities in an organic carbon deficient arid soil [ 179 ].…”

Biochar’s ability to mediate and facilitate microbial contamination degradation, as well as its carbon-sequestration potential, has sparked interest in recent years. The scope, possible advantages (economic and environmental), and future views are all evaluated in this review. We go over the many designed processes that are taking place and show why it is critical to look into biochar production for resource recovery and the role of bioengineered biochar in waste recycling. We concentrate on current breakthroughs in the fields of engineered biochar application techniques to systematically and sustainable technology. As a result, this paper describes the use of biomass for biochar production using various methods, as well as its use as an effective inclusion material to increase performance. The impact of biochar amendments on microbial colonisation, direct interspecies electron transfer, organic load minimization, and buffering maintenance is explored in detail. The majority of organic and inorganic (heavy metals) contaminants in the environment today are caused by human activities, such as mining and the use of chemical fertilizers and pesticides, which can be treated sustainably by using engineered biochar to promote the establishment of a sustainable engineered process by inducing the circular bioeconomy.
