“…The microorganism also influences a number of processes associated with the metabolism of biogenic elements, like sulphur [44], which may also explain why the biopreparation caused the rate of decrease to almost double in the content of sulphur in the control treatment. Dimitrov and Mitov [45] found that the content of nutrients in plants growing on soils contaminated with petroleum-derived substances depends much on the species of plant.…”

Petroleum and petroleum-derived products can contribute to the inhibition of growth and development of plants. Soil contamination by these compounds either hampers or makes difficult the intake of water and mineral salts from the substrate, and also breaks a number of metabolic processes. As a result of the deficiency of chlorophyll and nutrients, the affected plants grow deformed roots, shoots, leaves, and flowers, and show numerous chloroses and necroses.The objective of our research was to determine the effects of petrol, used engine oil, and diesel oil on select morphological parameters of Vicia faba L., and on the content of select nutrients and heavy metals in the leaves of plants. The effect of the bioremediation process initiated by biopreparation ZB-1 on the above-mentioned parameters was also determined. The analyzed plants were obtained from the Experimental Station of the University of Agriculture in Cracow, located in Mydlniki near Cracow. In June 2010, the soil placed in special containers was contaminated with petroleum-derived substances at a quantity of 6,000 mg per 1 kg of dry mass, by pouring it on the soil. Half of the objects were subjected to bioremediation. The evaluation of the morphology of plants and the structural elements of yield was made at the stage of technological maturity of broad bean seeds. The evaluation of heavy metals content was conducted using flame absorption spectrometry. The carbon, nitrogen, and sulphur content was determined in a Variomax CNS analyzer. The results of the experiment showed that diesel oil had the most adverse effects on the morphological parameters of plants. Engine oil caused a decrease in the nitrogen, carbon, and sulfur contents in the leaves of plants, but on the other hand this substance, like other petroleum-derived compounds, increased the content of most heavy metals. The effect of biopreparation was diverse and depended on the type of substance and on the analyzed parameter.The conducted experiment showed that petroleum-derived substances continued to adversely affect the growth of plants even three years after soil contamination. Additionally, it increased the accumulation of harmful substances in the organs of plants which could, in turn, seriously impact the economy and human health. However, the intensity of the impact depends on the type of derivative. Bioremediation supported by the use of microorganisms is an advantageous solution that permits the improving of the growth parameters of plants, as well as offsetting the harmful effects of petroleum-derived products upon the majority of the analyzed elements.

“…Numerous studies have demonstrated increased degradation of petroleum hydrocarbons (such as phenanthrene, benzo[a]pyrene, benzo[a]anthracene, chrysene, hexadecane, benzene, toluene etc.) as a result of modified microbial activity in the rhizosphere of grasses and legumes (Nichols et al 1997;Miya and Firestone 2001;Corgié et al 2003;Muratova et al 2003;Phillips et al 2006).…”

The organochlorine 1,2,3,4,5,6 hexachlorocyclohexane (HCH) is a broad-spectrum insecticide that was used on a large-scale worldwide. The soilplant-microbe system and its influence on HCH biodegradation are evaluated. A greenhouse experiment was designed to evaluate HCH dissipation and several microbial parameters among rhizosphere and bulk soil of two contrasting plants, Cytisus striatus (Hill) Rothm and Holcus lanatus L. Plants were grown for 180 days in three treatments: uncontaminated soil (control), uncontaminated soil inoculated with soil (3% w/w) from a HCH-contaminated site (INOC), and uncontaminated soil inoculated with soil (3% w/w) from the HCH-contaminated site and artificially contaminated to obtain 100 mg HCH kg −1 dry soil (100HCH-INOC). At harvest, plant biomass, soil water-extractable organic C, pH and Cl concentration, rhizosphere microbial densities (total heterotrophs, ammonifiers, amylolytics) and C substrate utilization patterns, and degradation of α-, β-, δ-and γ-HCH isomers were determined in bulk and rhizosphere soils. Soil solution Cl concentration was determined every 30 days throughout the entire growth period. Results demonstrate that both Cytisus striatus and Holcus lanatus can grow in soils with up to 100 mg HCH kg −1 . An enhanced degradation of α-HCH, but not β-or δ-HCH, was observed in the rhizosphere. Significant changes in the microbial densities were observed between bulk and rhizosphere soils of Cytisus, and an increase in C source utilization indicated changes in community level physiological profiles (CLPP) in the rhizosphere of this species when grown in contaminated soils. HCH dissipation was also greater in soils planted with this species. In accordance, increases in soil extractable C, Cl concentration and acidity were greater at the rhizosphere of Cytisus. Concentration of Cl in soil solutions also indicates greater HCH dechlorination in soils planted with Cytisus than Holcus. Results suggest that phytostimulation of bacteria present or added to soil is a promising approach to cleaning HCHcontaminated sites, and especially for biodegradation of α-HCH.

“…Although, crude oil spills in soil affect plants adversely by creating conditions which make essential nutrients like nitrogen and oxygen used for plant growth unavailable to them [4], plant roots can act as a substitute for the tilling of soil to incorporate additives (nutrients) and to improve aeration [6,43]. Therefore, plants with well-developed root system such as popular, willow [44] and reed (Phragmites australies), possessing specialized root vessels, aerenchyma which can release oxygen into the rhizosphere in deep soil layer [44,45] are preferentially selected for rhizoremediation.…”
