Bioremediation is a low-cost, clean, and environmentally friendly method in managing marine pollution. Despite its great potential, marine bioremediation has its own challenges. As an open system, limited nutrients and fluctuating environmental conditions in the ocean affect the metabolism of degrading microorganisms, thus influencing the biodegradation rate. Multiple strategies have been employed to enhance the bioremediation rate at varying degrees of success. This review discusses these strategies from the perspective of experimental studies under controlled conditions and their potential applications for bioremediation. The addition of nutrients or other electron acceptors (biostimulation), as well as competent microbes to the contaminated site (bioaugmentation), have been reported to enhance pollutant degradation rate. Further modifications, such as using immobilized cells and genetic engineering have been employed to enhance the effectiveness of bioaugmentation. It is possible to combine more than one of these strategies to complement each other. However, one should note that all the reports to date were mostly done at the laboratory scale. Further studies need to be conducted by considering other factors such as climate, location, and types of pollutants, for the improvement of pollutant removal from the marine environment as a whole.

“…The coefficient of variation (CV) is the ratio of the standard deviation to mean expressed in percentage. For a model to be considered reliable, its CV should not be greater than 10 %, therefore a CV of 6.45 % obtained may be considered adequate and can, therefore, be used for predicting a response (Agarry, 2017).…”

The activities involved in the production and exploration of crude oil has constantly polluted the environment. This study investigated the ability of an indigenous fungus to utilize petroleum hydrocarbon. Response Surface Methodology was used to optimize the effects of pH, microbial concentration (spores/ml), and contact time (days) on the crude oil removal efficiency in refinery effluent. Monocillium sp. was isolated and used for the treatment of refinery effluent due to its predominance in the contaminated soil. Twenty experimental runs were analyzed to determine the effect of pH, microbial concentration and contact time on the oil removal efficiency. From theexperimental results obtained, a maximum oil removal efficiency of 98.42 % was achieved at a pH of 6.5, contact time of 14 days, and a microbial concentration of 3 spores/ml. The results obtained showed the percentage of crude oil removal in the effluent sample increased with an increase in time. Optimization of the experimental result was achieved at a removal efficiency of 98.59 %, a contact time of 13.96 days, a pH of 6.85, and a microbial concentration of 3.01 spores/ml. The findings of this study revealed that Monocillium sp. is a viable hydrocarbon degrader, and can be used in the bioremediation of petroleum contaminated environments. Keywords: Response surface, optimization, bioremediation, hydrocarbon, removal efficiency, Monocillium sp.

“…Interestingly, this approach employs several "omics" approaches such as metagenomics, metatranscriptomics, and metaproteomics [11]. Given the incessant oil spillage, a number of laboratory-based bioremediation and bioaugmentation studies have emerged from the Niger Delta in an attempt to restore the region [29][30][31][32][33]. However, none of the bioremediation strategy has been optimized using system biology and "omics" techniques.…”

There have been reported cases of incessant crude oil spills leading to severe instances of hydrocarbon pollution in many parts of the Niger Delta region of Nigeria. The United Nations Environmental Programme (UNEP) in 2011 reported widespread hydrocarbon contamination in Ogoniland severely impacting many components of the environment. Some clean up and remediation methods including bioremediation, thermal treatment, and soil vapour extraction amongst others have been suggested as panacea to the restoration of the severely polluted environments in the region. Amongst these methods, bioremediation stands out. Interestingly omics based techniques have been shown to be amendable to bioremediation with a number of potential benefits. This review paper examines the potential benefits of the omics based technologies in the remediation of hydrocarbon polluted sites in the Niger Delta region of Nigeria.
