“…Tis level of oil destruction efectivity is comparable with data obtained from our feld studies in 6 months. However, using Pseudomonas aeruginosa BB-BE3 together with Azadirachta indica plants showed 95.71% removal of hydrocarbons from soil [30], so it is perspective to use Pseudomonas mendocina H-3 together with Kazakhstan plants to get this level.…”

The culture of Pseudomonas mendocina H-3 was selected as the microorganism for oil destruction, and its effect on oil-contaminated soil from the Zhanazhol deposit in West Kazakhstan was studied. After conducting model laboratory experiments, field experiments were carried out. Six and twelve months after the treatment of the oil-contaminated field with microorganisms, the amount of oil fractions in the soil decreased noticeably, while the content of asphaltenes remained constant. Analyses show that the composition of the oil fraction changes—the concentration of paraffin-naphthenic—polycycloaromatic components decreases, whereas the relative amount of mono- and bicycloaromatic hydrocarbons increases. The results of the efficiency assessment showed that the use of Pseudomonas mendocina H-3 cell suspension in natural conditions leads to a decrease in the content of hydrocarbons in the soil from 55 to 70%. The lower efficiency of bioremediation with cell cultures in field experiments (on average, 61%) compared with laboratory model studies (reduction of oil content to 79%) is apparently associated with climatic conditions.

“…Bacteria and fungi are the main microorganisms that can degrade petroleum hydrocarbons in soil [24]. Bhuyan et al [25] isolated two strains of Pseudomonas aeruginosa, which have high efficiency of petroleum hydrocarbons degradation and plant growth promotion ability, and could be used for subsequent bioremediation of crude oil-contaminated soil. Kumari et al [26] investigated the ability of Pseudomonas aeruginosa to degrade multiple polycyclic aromatic hydrocarbons in crude oil and found that Pseudomonas aeruginosa had a high biodegradation rate for specific PAHs in petroleum, such as 67.1% for phenanthrene and 61.0% for benzo(b)fluoranthene.…”

Contamination of soil by petroleum is becoming increasingly serious in the world today. However, the research on gene functional characteristics, metabolites and distribution of microbial genomes in oil-contaminated soil is limited. Considering that, metagenomic and metabonomic were used to detect microbes and metabolites in oil-contaminated soil, and the changes of functional pathways were analyzed. We found that oil pollution significantly changed the composition of soil microorganisms and metabolites, and promoted the relative abundance of Pseudoxanthomonas, Pseudomonas, Mycobacterium, Immundisolibacter, etc. The degradation of toluene, xylene, polycyclic aromatic hydrocarbon and fluorobenzoate increased in Xenobiotics biodegradation and metabolism. Key monooxygenases and dioxygenase systems were regulated to promote ring opening and degradation of aromatic hydrocarbons. Metabolite contents of polycyclic aromatic hydrocarbons (PAHs) such as 9-fluoronone and gentisic acid increased significantly. The soil microbiome degraded petroleum pollutants into small molecular substances and promoted the bioremediation of petroleum-contaminated soil. Besides, we discovered the complete degradation pathway of petroleum-contaminated soil microorganisms to generate gentisic acid from the hydroxylation of naphthalene in PAHs by salicylic acid. This study offers important insights into bioremediation of oil-contaminated soil from the aspect of molecular regulation mechanism and provides a theoretical basis for the screening of new oil degrading bacteria.

“…Gordonia amicalis, in symbiotic association with Azadirachta indica, found to be effective in degrading total petroleum hydrocarbon 36 . TPH concentrations decreased while soil biological activity and nutrient content increased when P. aeruginosa N3 as well as P. aeruginosa N4 bacteria degrades crude oil, were used.…”

The presence of a component, impurity, or other unfavourable element that taints, corrupts, infects, renders unfit, or degrades a material, or natural environment is referred to as environmental contamination. Due to the potential negative effects caused by the chemical discharges, environmental issues have now become crucial factors to consider. Petrochemical wastes are one of the most serious environmental contaminants which comprise a large group of chemicals derived from petroleum and natural gases. The petrochemical pollutants, belonging to the groups such as greenhouse gases, volatile organic compounds, Particulate Matter (PM) with heavy metals, and polycyclic aromatic compounds, act as potential soil contaminants, causing disturbance and harm to the soil ecosystem. Phytoremediation is an emerging and eco-friendly way to mitigate petrochemical contamination of soil. It is an in situ technique to purify contaminated soil or water using plants (trees, shrubs, grasses and aquatic plants) and their associated microorganisms. This technique is favourable for tropical countries like India where there is immense growth of plants. Though plants like Mirabilis jalapa, Italian ryegrass, sorghum, maize, and alfalfa are used worldwide, in Assam also various plant species are used for remediation purposes in petrochemical-contaminated soil. Crotalaria pallida, Cyperus brevifolius, Cynodondactylon. Mimosa pudica etc. are some of the plant species that have been reported to possess the ability to degrade toxic chemicals into non-toxic or less-toxic products with the aid of microbial colonies in the soil. This review is an effort to through some light on the plants of Assam as well as worldwide along with their family in the remediation of petroleum-contaminated soil. Thus, it will be helpful to select appropriate plants for the purpose of phytoremediation.
