مستخلص المنشور

Environmental pollution caused by fossil fuel is an issue of the
greatest importance regarding both economic growth and ecological
restoration. Among fossil fuels, oil (petroleum hydrocarbon)
is the principle source of energy, and it is part of major
global environmental pollutants. Significant amounts of
hydrocarbons from petroleum products contaminate
groundwater and soil due to leaks and spills from petroleum
refinery processes, oil storage tanks, and transportation
(Su et al. 2011). Hydrocarbon disposal often leads to
release of hydrocarbon pollutants into the environment that
bring a serious ecological problems. These petroleum pollutants
are both toxic to biological components of the
environment and carcinogenic (Okoh 2006; Okoh and
Trejo-Hernandez 2006; Obayori 2009).
Bioremediation is a process used for the degradation
of hydrophobic organic compounds (HOCs) in oilcontaminated
water and soil due to its environmental
and economic advantages over other physicochemical
remediation methods (Silva et al. 2014). So far, the
main approach for enhancing the bioavailability of
HOCs is the use of synthetic or natural surfactants
(Walters and Aitken 2001; Mulligan 2005; Zhu and
Aitken 2010), which promote the solubility of HOCs and
improve the biodegradation process (Zheng et al. 2012).
