“…Nanekar et al [57] proved that adding extra microorganisms (bioaugmentation) to the soil contaminated with petroleum-derived compounds decreased the amount of total petroleum hydrocarbons (TPH) in the soil, and also resulted in lowering the lead, cadmium, and zinc content while increasing manganese content. Most often, these results coincide with the outcome of our experiment.…”

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.

“…However, there were no significant differences (P < 0.05) between the compost and vermicompost amendment on the removal of total ash-PAHs. The higher PAH removal in PCA and PVA treatments than in other treatments indicated that the maize plants could stimulate the growth and activity of soil autochthonous microorganism involved in PAH degradation due to the production of exudates released in maize rhizosphere as was reported by Nanekar et al (2015). Moreover, the compost or vermicompost used together with maize could stimulate the activity of soil autochthonous PAH degraders which could be supported by PAH degraders augmented to soil from the amendments.…”

Phytoremediation using maize (Zea mays L.) assisted by the compost or vermicompost amendments was the most appropriate strategy for bioremediation of soil contaminated by polycyclic aromatic hydrocarbons (PAHs) derived from biomass fly ash. Higher removal of low molecular weight PAHs than medium and high molecular weight PAHs within the same treatment were observed. The total PAH content in planted soil with compost or vermicompost was decreased in a range between 62.9–64.9%. There were no significant differences (P < 0.05) between the compost and vermicompost amendments on the total removal of ash-PAHs. The content of PAH derived by ash did not have adverse effect on maize cultivation and biomass yield. The contribution of PAH reduction by maize roots on the soil total PAH removal was negligible. Therefore, maize significantly boosted the PAH removal in soil. The harvested maize shoots did not represent any environmental risk.

“…It majorly covers several remedial technologies which enhance biodegradation of the contaminant by supplementing soils with growth substrates/co-substrates. The most common biostimulation agents include bulking agents, nutrient supplementation, halogenated priming compounds (halo-priming), and surfactants (Passatore et al 2014; Nanekar et al 2015). The rate of PCB dechlorination can be increased by priming with halogenated compound.…”

In recent years, microbial degradation and bioremediation approaches of polychlorinated biphenyls (PCBs) have been studied extensively considering their toxicity, carcinogenicity and persistency potential in the environment. In this direction, different catabolic enzymes have been identified and reported for biodegradation of different PCB congeners along with optimization of biological processes. A genome analysis of PCB-degrading bacteria has led in an improved understanding of their metabolic potential and adaptation to stressful conditions. However, many stones in this area are left unturned. For example, the role and diversity of uncultivable microbes in PCB degradation are still not fully understood. Improved knowledge and understanding on this front will open up new avenues for improved bioremediation technologies which will bring economic, environmental and societal benefits. This article highlights on recent advances in bioremediation of PCBs in soil. It is demonstrated that bioremediation is the most effective and innovative technology which includes biostimulation, bioaugmentation, phytoremediation and rhizoremediation and acts as a model solution for pollution abatement. More recently, transgenic plants and genetically modified microorganisms have proved to be revolutionary in the bioremediation of PCBs. Additionally, other important aspects such as pretreatment using chemical/physical agents for enhanced biodegradation are also addressed. Efforts have been made to identify challenges, research gaps and necessary approaches which in future, can be harnessed for successful use of bioremediation under field conditions. Emphases have been given on the quality/efficiency of bioremediation technology and its related cost which determines its ultimate acceptability.
