Biosurfactant production from Palm Oil Mill Effluent (POME) for applications as oil field chemical in Nigeria.

Abstract

The interest of Petroleum industry in biosurfactant production has increased considerably in recent years as a possible replacement for chemical surfactants which are known for their high toxicity and non-degradability. Biosurfactants are amphiphillic surface active agents produced by microrganisms. They are biodegradable and have been found useful in oil field applications such as bioremediation of hydrocarbon impacted media due to their enhanced oil recovery ability, solubilisation, removal of oil from contaminated soil and sludge in oil storage tanks, dispersion of oil spills, transfer of crude oil and bioremediation of recalcitrant molecules without a residual toxic effect on the environment. These properties make their usage more advantageous over their synthetic counterparts. Biosurfactants can be obtained with the use of agro-industrial waste such as Palm Oil Mill Effluent (POME) as substrate, this helps to reduce overall production costs. Microrganisms have demonstrated the ability to utilize POME as a carbon source accompanied with biosurfactant production. This is due to their unique metabolic pathways which makes them a useful tool in the bio-industry. Production of biosurfactants from POME will not only reduce its production cost but will also encourage the use of our indigenous raw material thus reducing the amount of waste released into the environment and contributing immensely to sustainable waste management. The present review describes the production of biosurfactant from POME and its applications in oil field industry.

Isolation and characterization of biosurfactant producing bacteria from Mile 2 and Ologe Lagoons, Nigeria

“…The oil used in this study include crude oil, groundnut oil and palm oil. Various types of edible oils have been used to stimulate biosurfactant production, but there is limited report on the use of groundnut oil (Chittepu, 2019) and palm oil for biosurfactant production (Wan Nawawi et al, 2010;Saisa-Ard et al, 2013;Hope 2015). The oil and palm oil are common oils used in the Nigerian environments and usually find their way into the water systems.…”

Process Optimization of Palm Oil Mill Effluent-Based Biosurfactant of Halomonas meridiana BK-AB4 Originated from Bledug Kuwu Mud Volcano in Central Java for Microbial Enhanced Oil Recovery

“…The results of the RSM approach to determine the optimum conditions for biosurfactant production by varying the POME concentration, incubation time, NaCl concentration, and pH are presented in Table 2 below. Several studies comparing the use of several alternative carbon sources show that POME can help microorganisms produce good biosurfactants in reducing surface tension and emulsification [31]. The economic value of POME can solve the problem of the high cost of applying EOR and MEOR methods.…”

Emerging trends in POME treatment and applications: chemical and biotechnological aspects

“…Among the many and more recent treatment alternative techniques are the biological options of (an)aerobic therapies and chemical techniques. While some of the techniques of choice must, within a reasonable timeframe, offer the best results in terms of waste management -reduction in chemical oxygen demand (COD) and biochemical oxygen demand (BOD), others assist in useful product recovery including but not limited to biofuels, biofertilizers, and bioproducts (Ahmad et al, 2020;Damaraju et al, 2019;Hope & Gideon, 2015;Ndubuisi-Nnaji et al, 2020). Various methodologies have been studied for developing low-priced and active treatment techniques, including the integrated anaerobic-aerobic bioreactor (IAAB) system.…”
