Biological treatment of oil spills: Biological agents are mostly naturally produced microorganisms, nutrient or enzymes that enhances the rate of bio-degradation of oil spills. It is the process of digestion of oil spills through microorganisms such as fungi, bacteria, yeasts, etc., it is a simple process of breaking f complex compound to form simpler molecular giving out energy and nutrients. Bio-degradation of oil is a natural process that takes place over a long period of time (days, weeks, months or even over years) to degrade oil from the water. Bio-remediation is a technique of adding matters like fertilizers or micro-organisms to the area in need if remediation from oil spills. Bio remediation aids the degradation process through…show more content…
Thus, diverse slow release nutrient sources were used with the oil sorbent materials. The plant-derived materials from mosses, duckweeds and other plant species are suitable for immobilization of microorganisms and preserve their viability for a longer time. In the present work the bioremediation performance of a new type of bio-hybrid material constituted by the mix of dry biomass of duckweed plants (Wolffia arrhiza, Lemna minuscula) and their biomass-derived cell-structured materials (CSM) incorporated in a non-woven polymer matrix of methyl methacrylate-acrylonitrile and hydrocarbon degrading bacteria immobilized on its surface. On comparison the crude oil biodegradation capacities of the new BHM and assessment of the combined effect of the plant material incorporation and immobilization of oil-degrading bacteria cells on the performance of these materials. These materials turned to be highly capable of oil absorption from sea water and, more importantly, facilitated significantly the biodegradation of the absorbed oil (Lobakoa, 2016). Using halothermophilic bacterial consortium or the biodegradation of PAHs: Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants, difficult to clean due to their hydrophobic nature. The hydrocarbons possess toxic, carcinogenic and mutagenic properties. Saudi Arabia holds about one-fifth of the world's total conventional oil reserves, producing approximately 10.3 million barrel per day. Saudi Arabia also possesses
