“…The biostimulation of native microbial communities of petroleum-impacted soil can be achieved in several ways. A wide range of organic and inorganic agents including nutrients, surfactants, fresh and composted sewage sludge and manure have been found to be successful biostimulators for petroleum hydrocarbon degradation [79],[80],[81]. Various laboratory and field experiments based on the addition of inorganic and organic fertilizers to the contaminated environment have shown positive impacts on hydrocarbon degradation; however a range of outcomes have been reported.…”

Increasing industrialisation, continued population growth and heavy demand and reliance on petrochemical products have led to unprecedented economic growth and development. However, inevitably this dependence on fossil fuels has resulted in serious environmental issues over recent decades. The eco-toxicity and the potential health implications that petroleum hydrocarbons pose for both environmental and human health have led to increased interest in developing environmental biotechnology-based methodologies to detoxify environments impacted by petrogenic compounds. Different approaches have been applied for remediating polluted sites with petroleum derivatives. Bioremediation represents an environmentally sustainable and economical emerging technology for maximizing the metabolism of organic pollutants and minimizing the ecological effects of oil spills. Bioremediation relies on microbial metabolic activities in the presence of optimal ecological factors and necessary nutrients to transform organic pollutants such as petrogenic hydrocarbons. Although, biodegradation often takes longer than traditional remediation methods, the complete degradation of the contaminant is often accomplished. Hydrocarbon biodegradation in soil is determined by a number of environmental and biological factors varying from site to site such as the pH of the soil, temperature, oxygen availability and nutrient content, the growth and survival of hydrocarbon-degrading microbes and bioavailability of pollutants to microbial attack. In this review we have attempted to broaden the perspectives of scientists working in bioremediation. We focus on the most common bioremediation technologies currently used for soil remediation and the mechanisms underlying the degradation of petrogenic hydrocarbons by microorganisms.

“…Oil pollution can occur on a large scale such as ocean and land spills, with devastating effects on macro- and micro-organisms living in these environments. Oil contains thousands of compounds and some of them such as polycyclic aromatic hydrocarbons (PAHs) are toxic and carcinogenic [1] , [2] . Bioremediation or the use of microbes (mainly bacteria and fungi) represents a promising, cheap approach to the degradation or clean up of PAH-polluted environments.…”

“…Biosurfactant classification is mostly based on the biosurfactants' chemical composition and origin (Sharma et al 2016b). They are divided into two categories: (a) surfactants derived from microorganisms, such as glycolipids (rhamnolipids, trehalolipids, and sorphorolipids), lipopeptides, surfactins, lichenysin, and phospholipids (Vijayakuma, Saravanan 2015;Gudiña et al 2016), and (b) surfactants derived from plants such as saponin (Kommalapati et al 1996;Zhou et al 2013;Iglesias et al, 2014;Blyth et al 2015). Biosurfactants are low-molecular-weight surface-active agents that efficiently lower surface and interfacial tension; this group includes glycolipids, lipopeptides, and phospholipids; bioemulsifiers are high-molecular-weight polymers that are more effective as emulsion-stabilizing agents (Xia et al 2014;Saenz Marta et al 2015).…”

The dispersal of various chemical pollutants in our environment requires the development of effective approaches that would lead to the bioremediation of contaminated areas. The biological methods such as the application of microbial biosurfactants represent one of the suitable solutions that has gained large attention due to their structural diversity, molecular sizes, and multifunctional characteristics. Thus, they are likely to be applied in the field of bioremediation, where they can lower the surface and interfacial tensions at different interfaces leading to removal of pollutants or improve their biodegradation and bioavailability. The presented review highlights the recent advances and knowledge on the important aspects of microbial biosurfactant applications in bioremediation.
