Leo), sunflower ( Helianthus annuus ), southern crabgrass ( Digitaria sanguinalis ), red clover ( Trifolium pratense ), beggar ticks ( Bidens cernua ), and sedge species ( Cyperus rotundus ) may be effective (Radwan et al, 1995; Wiltse et al, 1998; Chaineau et al, 2000; Huang et al, 2004; Parrish et al, 2004; Rutherford et al, 2005; Kaimi et al, 2007; Muratova et al, 2008; Shirdam et al, 2008; Ayotamuno et al, 2010; Tang et al, 2010; Yousaf et al, 2010; Hall et al, 2011; Basumatary et al, 2012, 2013). In general, the positive influence of leguminous plants is attributed in part to their ability to increase soil nitrogen concentrations in soils with high C:N ratio, whereas the positive contributions provided by grasses are correlated with their fibrous root systems, large root surface and deeper penetration into the soil matrix (Gaskin et al, 2008; Rezek et al, 2008).…”

Widespread pollution of terrestrial ecosystems with petroleum hydrocarbons (PHCs) has generated a need for remediation and, given that many PHCs are biodegradable, bio- and phyto-remediation are often viable approaches for active and passive remediation. This review focuses on phytoremediation with particular interest on the interactions between and use of plant-associated bacteria to restore PHC polluted sites. Plant-associated bacteria include endophytic, phyllospheric, and rhizospheric bacteria, and cooperation between these bacteria and their host plants allows for greater plant survivability and treatment outcomes in contaminated sites. Bacterially driven PHC bioremediation is attributed to the presence of diverse suites of metabolic genes for aliphatic and aromatic hydrocarbons, along with a broader suite of physiological properties including biosurfactant production, biofilm formation, chemotaxis to hydrocarbons, and flexibility in cell-surface hydrophobicity. In soils impacted by PHC contamination, microbial bioremediation generally relies on the addition of high-energy electron acceptors (e.g., oxygen) and fertilization to supply limiting nutrients (e.g., nitrogen, phosphorous, potassium) in the face of excess PHC carbon. As an alternative, the addition of plants can greatly improve bioremediation rates and outcomes as plants provide microbial habitats, improve soil porosity (thereby increasing mass transfer of substrates and electron acceptors), and exchange limiting nutrients with their microbial counterparts. In return, plant-associated microorganisms improve plant growth by reducing soil toxicity through contaminant removal, producing plant growth promoting metabolites, liberating sequestered plant nutrients from soil, fixing nitrogen, and more generally establishing the foundations of soil nutrient cycling. In a practical and applied sense, the collective action of plants and their associated microorganisms is advantageous for remediation of PHC contaminated soil in terms of overall cost and success rates for in situ implementation in a diversity of environments. Mechanistically, there remain biological unknowns that present challenges for applying bio- and phyto-remediation technologies without having a deep prior understanding of individual target sites. In this review, evidence from traditional and modern omics technologies is discussed to provide a framework for plant–microbe interactions during PHC remediation. The potential for integrating multiple molecular and computational techniques to evaluate linkages between microbial communities, plant communities and ecosystem processes is explored with an eye on improving phytoremediation of PHC contaminated sites.

Changes in crude oil production and distribution have increased the incidence of oil spills throughout the world. Oil spills often cause destructive effects on aquatic and land ecosystems. The oil spill cleanup and recovery techniques are challenging and usually involve complex mechanical, chemical, and biological methods. Usually, mechanical removal of free oil is utilized as an effective strategy for cleanup in aquatic and terrestrial environments; however, they are expensive and need specialist personnel and equipment. The other commonly used method is the application of chemical materials such as dispersants, cleaners, demulsifiers, biosurfactants, and soil oxidizers. Nevertheless, these reagents can have potential harmful environmental impacts, which may limit their application. As an alternative, bioremediation can offer reduced environment risk; however, the limitations of microbial activity in the soil can make this option unsuitable. One area of bioremediation is phytoremediation, which offers potential for restoring large areas of contaminated ground. Plants are able to remove pollutants through processes such as biodegradation, phytovolatilization, accumulation, and metabolic transformation. This review presents the fate of crude oil spills in aquatic and land ecosystems and their environmental effects. Furthermore, the paper focuses on crude oil phytoremediation and its applications in polluted ecosystems.

“…Nevertheless, microbial degradation of PAHs in soil is restricted by various factors that often results in lower bioremediation efficiency than the expected level (Arun and Eyini 2011). Plant species like Cyperus odoratus, Cyperus laevigatus, Cyperus rotandus and Cyperus bravifolius have been identified for the degradation of total petroleum hydrocarbons by adding inorganic supplements (Basumatary et al 2012). Aquatic weeds Typha spp.…”

Contamination by polycyclic aromatic hydrocarbons and heavy metals is a rather serious problem across the world and poses a major threat to living organisms. These are considered to be carcinogens and are constituents of oil sludge. The magnitude of PAHs released into the environment has increased drastically in recent times. This is mostly due to petroleum waste or seepage during transportation of crude oil. There have been several instances of oil spills on the coasts of India and elsewhere. In northeast India, PAHs pollution is evident at the sites of drilling and refinery sites. The boiling points of high molecular weight PAHs are very high and they are almost difficult to decompose. Their hydrophobicity causes these compounds to accumulate and sequester in soil organic matter; thus, their desorption from soil limits the efficiency of biodegradation in situ. This chapter will focus on the various case studies where plant-microbe association has been used to assist bioremediation process of PAHs and heavy metals in oilcontaminated soil. Topics to be covered include how plants and microbes together effect the remediation process, bioavailability of PAHs, facilitating the movement of essential nutrients, air and water and production of biosurfactants in faster acceleration of the removal process.
