“…They observed that forage grasses developed in fine-textured soils; in contrast to soils with coarse texture where grass could not develop. Varjani and Upasani (2019) and Zhang et al (2020) reported this behavior to the specific characteristics of each region since they found a higher rate of degradation of hydrocarbons in tropical areas compared to colder zones (unlike temperate zones, in tropical, there is greater variability of temperatures and rainfall throughout the year which contributes to high biological activity that promote degradation). Other studies estimate that the degradation of a pollutant could vary according to the soil and the hydrocarbons properties since it has been observed that although light oils tend to move more easily on the soil matrix, they also tend to degrade faster than heavy oils (Ite and Ibok, 2019;Velázquez-Vázquez et al, 2022).…”

“…Tall fescue can remove 48.4% of oil pollution after 70 days of restoration when the soil oil concentration is 5% [168]. Microorganisms could remove 15% of petroleum pollutants after 70 days of remediation when the soil oil content is 5.6% [169]. When soil oil levels are too high, it is hazardous to plants and microorganisms, reducing their capacity to degrade petroleum contaminants and potentially causing deaths in microorganisms and plants.…”

Remediation of Petroleum-Contaminated Soils with Microbial and Microbial Combined Methods: Advances, Mechanisms, and Challenges

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.

“…The photosynthetic bacteria in CM2 had a bigger influence to decrease the salinity. Zhang et al (2020) shows that pH is a great indicator of the remediation of soil 29 . In this study, no significant changes (p ≺ 0.05) in the soil pH were observed in blank sample throughout the experiment.…”

“…The salinity of the soil was measured once a week by using EC measurement 15 , 17 . All laboratory tests were carried out in a fixed ambient temperature of 25 °C to avoid the effect of temperature 8 , 29 . The water content was fixed to be around 20% by providing water once a week which was also monitored during the experiment by conducting the water content test by following Japanese geotechnical society (JGS) method 30 .…”

In this research, bioremediation of tsunami-affected polluted soil has been conducted by using collective microorganisms and recycled waste glass. The Tohoku earthquake, which was a mega earthquake in Japan triggered a huge tsunami on March 11th, 2011 that caused immeasurable damage to the geo-environmental conditions by polluting the soil with heavy metals and excessive salt content. Traditional methods to clean this polluted soil was not possible due to the excess cost and efforts. Laboratory experiments were conducted to examine the capability of bioremediation of saline soil by using recycled waste glass. Different collective microorganisms which were incubated inside the laboratory were used. The electrical conductivity (EC) was measured at different specified depths. It was noticed that the electrical conductivity decreased with the assist of the microbial metabolisms significantly. Collective microorganisms (CM2) were the highly capable to reduce salinity (up to 75%) while using recycled waste glass as their habitat.
