“…A much higher degradation of crude oil in contaminated soil by Leptochloa fusca (51%) and Brachiaria mutica (61%) was reported by Fatima et al [21]. Further, different degradation mechanisms of plants, such as uptake oil from soil and transformation inside the plant, have been reported [50,51]. Furthermore, it has been reported that combining plant and bacteria results in higher degradation of crude oil, i.e., in the range of 78% to 85% [21] and 85% [11].…”

Crude oil pollution of soil is a serious environmental issue, and bioremediation using plants and microorganisms is a natural and sustainable method for its restoration. Pot incubation of a two-factor randomized block (plants with two levels, and crude oil with three levels) was designed to investigate the rhizosphere bacterial community of Suaeda salsa (L.) Pall. Crude oil contamination of soil was studied at different levels: 2 g/kg (low), 4 g/kg (medium), and 6 g/kg (high) levels. In this study, the physicochemical properties of the collected rhizosphere soil were analyzed. Moreover, the soil bacteria were further identified using the 16S rRNA gene. The effects of S. salsa and crude oil and their interaction on the physiochemical properties of the soil and crude oil degradation were found to be significant. Crude oil significantly influenced the diversity and evenness of bacteria, while the effects of S. salsa and interaction with crude oil were not significant. Proteobacteria were found to be dominant at the phylum level. Meanwhile, at the genera level, Saccharibacteria and Alcanivorax increased significantly in the low and medium contamination treatment groups with S. salsa, whereas Saccharibacteria and Desulfuromonas were prevalent in the high contamination treatment group. High crude oil contamination led to a significant decrease in the bacterial diversity in soil, while the effects of S. salsa and its interaction were not significant. Despite the highest abundance of crude oil degradation bacteria, S. salsa reduced crude oil degradation bacteria and increased bacteria related to sulfur, phosphorus, and nitrogen cycling in the low and high contamination group, whereas the opposite effect was observed for the medium contamination treatment group. The abundance of most crude oil degradation bacteria is negatively correlated with crude oil content. Nitrogen cycling bacteria are sensitive to the total nitrogen, total phosphorus, ammonia nitrogen, and nitrate nitrogen, and pH of the soil. Sulfur cycling bacteria are sensitive to aromatic hydrocarbons, saturated hydrocarbons, and asphaltene in soil. This research is helpful for further studying the mechanism of synergistic degradation by S. salsa and bacteria.

Lysinibacillus sphaericus is known for its great larvicidal activity against mosquito larvae and toxic metal resistance, but knowledge about its possible activity in soil is scarce and poor. Nevertheless, in the genome of some strains have been reported genes of nitrogen cycle. Seven L. sphaericus strains were tested as nitrogen fixing bacteria, nitrifying bacteria, and indoleacetic acid producer. Subsequently a consortium was formulated using the best strains (CBAM5, III(3)7, OT4b.31, and OT4b.49) to evaluate its effect in Canavalia ensiformis growth and lead phytoremediation. All L. sphaericus strains were able to fix nitrogen (0.61–1.47 mg/L of ammonium), nitrify (0.26–0.7 mg/L of nitrate), and produce IAA (3.3–5.5 µg/mL in L‐tryptophan media and 0.3–1.1 µg/mL in trypticase broth). They also promoted shoot length, root length, foliar area, and leaf number in C. ensiformis, enhanced lead bioaccumulation in the root reaching a removal of 40% of lead in greenhouse experiment, and increased nitrate content in soil twofold in contrast to the control in field experiment. Therefore, L. sphaericus could be a key organism in the formulation of biofertilizers, as it shows potential in the phytoremediation processes, in crop plant nutrition, and growth in low nutrient polluted soils, then is a plant growth promoter bacteria (PGPB). © 2017 American Institute of Chemical Engineers Environ Prog, 37: 276–282, 2018

“…Regarding the ODS, STS, RS oil sludges, the total EPH concentrations were lower than the suggested clean-up level of 10,000 ppm in soils in industrial areas (Shelley et al, 1997), so bioremediation techniques such as landfarming and phytoremediation of these oil sludges can be used to treat these sludges by its amending to a designated soil area (Ramirez and Dussan, 2014). In addition, the PTEs concentrations of these sludges (except for Zn) were lower than the 2,500-ppm threshold (Table S 1).…”

potentially toxic elements (PTEs) are believed to come from oil additives (de Souza et al., 2014).da Silva et al. (2012) reported that the composition of oil sludge is about 30 to 90% water, 4 to 7% sediments, and to 60% oil. However, Saikia et al. (2003) stated that the typical composition of oil sludge is 30-50% water, 10-12% sediments and solids, 30-50% oil. Yang et al. (2005), Zhang et al. (2012), and Long et al. (2013 have agreed that oil sludge is usually composed of 30-70% water, 2 to 15% sediments and solids, and 30-90% oil. Moreover, Egazar'yants et al. (2015) mentioned that oil sludges can have approximately 10 to 56 wt.% organic materials, 30 to 85 wt.% water and 1 to 46 wt.% solids or sediments. This shows that there is no uniform agreement among authors on the detailed oil sludge composition. This is not surprising since each oil sludge composition is unique, and depends on the origin of the oil sludge (Viana et al., 2015). Consequently, the physicochemical characteristics vary according to the nature of the oil (Oliveira et al., 2015) and the formation process and storage of the oil sludge (Kadiev et al., 2015). Generally, the sediment content is less than the oil and water contents. The oil usually had higher aliphatic hydrocarbon percentages (40-60%) than the aromatic hydrocarbon percentages (25-40%) (Shie et al., 2004, Speight, 2006. This wide variation in the composition of oil sludges has significant implications on the characterisation of oil sludges because different procedures and methods have been applied to study different types of sludges (Heidarzadeh et al., 2010, Wang et al., 2010, Zhang et al., 2011, Jasmine and Mukherji, 2015. In turn, this is extremely relevant for quick decision-making purposes regarding the appropriate treatment of this waste. Currently, the treatment of oil sludges is aimed to either reduce the contaminants in the sludge or to recover the oil. The former includes some methods such as encapsulation (Johnson et al., 2015), bioremediation (Wang et al., 2016, Roy et al., 2018), and incineration (Gong et al., 2017 whereas the latter, the oil recovery methods, include freeze/thawing (Hu et al., 2015), solvent extraction (Hu et al., 2017, * These elements are potentially toxic elements (PTEs) (Shaheen et al., 2016).Values in bold are over the limit of the acceptable standards of landfilling of hazardous waste established by the European Union: As (25 µg•g -1 ), Cd (5), Cr (70), Cu (100), Ni (40), Pb (50), Zn (200) (Kriipsalu et al., 2008). The mean values with the standard deviation (in parentheses) are shown (n = 3).
