“…Environmental pollution with crude oil has been a serious worldwide environmental concern [1,2]. Crude oil causes drinking water pollution [3,4], decline in the water and air quality as well as soil fertility, and wastage of non-renewable resources [5][6][7][8][9]. This damage to the ecosystem is due to the accidental leakage of crude oil or its derivatives.…”

“…Dynamic synergy between plant roots and soil microbes has received considerable attention owing to the possible role of bacteria in plant growth and the degradation of petroleum hydrocarbons [30]. Numerous microorganisms such as bacteria and fungi inhabit the rhizosphere, and contribute to plant restoration in the root zone [9,31]. For example, the root activity of alfalfa and perennial ryegrass increases the amount of rhizosphere bacteria capable of degrading crude oil in the soil [32].…”

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.

“…Salicornia europaea L. is an annual halophyte from the Chenopodiaceae family (Piernik et al 2017) and one of the plants that has the highest salt tolerance (greater than 1 M NaCl) in the world (Rozema and Schat 2013;Zare-Maivan et al 2015) and therefore well adapted in an environment where the level of soil salinity is as high as half-strength of seawater (Ebadi et al 2018). It is widespread in Urmia Lake, Iran (Zare-Maivan et al 2015), Europe, South Africa, South Asia, and North America and prevalent in salt-affected areas near coastlines, tidal floodways, salt lakes, and brine springs (Piernik et al 2017).…”

Irrigation of Salicornia europaea with heavy metal-polluted wastewater is a promising alternative method for risk mitigation of the Urmia Lake ecosystem from uncontrolled sewage. The objective of the study was to evaluate morphological and physicochemical responses of Salicornia europaea under wastewater irrigation at different growth stages. A field experiment was conducted in a split-plot experiment based on randomized complete block design with four replications. Treatments included control and wastewater irrigation (containing zinc (Zn), iron (Fe), copper (Cu), cadmium (Cd), lead (Pb), and nickel (Ni)) at three stages (vegetative, flowering, and reproductive) of plant growth and two times (two and 4 days in each stage). The result showed that the wastewater application at reproductive stage resulted in higher biomass production than that of the control plants. Wastewater irrigation at the flowering stage caused a significant increase in the amount of total chlorophyll and chlorophyll-a, while chlorophyll-b content was decreased at both flowering and reproductive stages. The amount of the total soluble protein was also affected, with wastewater irrigation showing the most significant increase at the reproductive stage. There was significant enhancement of osmolytes in leaves of plant under heavy metal stress, and the increased rate of proline was higher than soluble sugar at the flowering stage. Relative water content in Salicornia was not duration-and time-dependent. A 154% increase in catalase activity, 32% increase in peroxidase activity, and 57% increase in polyphenol oxidase activity were observed in the plant exposed to long-term wastewater duration. Based on the observed positive effect of wastewater on shoot length and weight, total soluble protein, proline, soluble sugar, enzyme activities, and plant biomass of Salicornia europaea, long-term effect of heavy metal-polluted wastewater irrigation can be approved for Salicornia crops in coastal areas.

“…Bioremediation technologies are nding wider and wider applications when compared with physical and chemical remediation methods owing to their high efficiency, low cost and harmless products (mainly CO 2 and water). 5 The critical factors in bioremediation are microbial quantity and activity, soil nutrients and oxygen status. However, petroleumcontaminated soil usually has a low number of microbes, low porosity and nutrients, limiting the degradation efficiency of microorganisms in practical application.…”
