Fuel and oil spills during the exploration, refining, and distribution of oil and petrochemicals are primarily responsible for the accumulation of organic pollutants in the environment. The reduction in contamination caused by hydrocarbons, heavy metals, oily effluents, and particulate matter generated by industrial activities and the efficient recovery of oil at great depths in an environmentally friendly way pose a challenge, as recovery and cleaning processes require the direct application of surface-active agents, detergents, degreasers, or solvents, often generating other environmental problems due to the toxicity and accumulation of these substances. Thus, the application of natural surface-active agents is an attractive solution. Due to their amphipathic structures, microbial surfactants solubilize oil through the formation of small aggregates (micelles) that disperse in water, with numerous applications in the petroleum industry. Biosurfactants have proven their usefulness in solubilizing oil trapped in rock, which is a prerequisite for enhanced oil recovery (EOR). Biosurfactants are also important biotechnological agents in anti-corrosion processes, preventing incrustations and the formation of biofilms on metallic surfaces, and are used in formulations of emulsifiers/demulsifiers, facilitate the transport of heavy oil through pipelines, and have other innovative applications in the oil industry. The use of natural surfactants can reduce the generation of pollutants from the use of synthetic detergents or chemical solvents without sacrificing economic gains for the oil industry. Therefore, investments in biotechnological processes are essential. It is predicted that, in the not-too-distant future, natural surfactants will become viable from an economic standpoint and dominate the world market. The application of biosurfactants in these settings would lead to industrial growth and environmental sustainability. The main goal of this paper is to provide an overview of diverse applications of biosurfactants on environmental remediation, petroleum biotechnology, and the oil industry through a scientific literature review.

Green surfactants have significant potential for improving environmental remediation methods. The aim of the present study was to formulate a green natural detergent containing the biosurfactant produced by Starmerella bombicola ATCC 22214 grown in 1.2% canola oil, 10% sucrose, and 0.5% corn steep liquor. The biosurfactant reduced surface tension to 31.84 mN/m and was produced at a yield of 22 g/L. Twelve formulations were proposed using cottonseed oil as the natural solvent and different stabilisers (vegetable wax, hydroxyethyl cellulose, and sodium alginate). The detergent was evaluated for its emulsifying capacity and stability over a 10-day period. Ecotoxicity was investigated using the marine recruitment test on metal plates covered with paint into which the biosurfactant was incorporated as well as tests with a microcrustacean and vegetable seeds. The formulation designated H, consisting of 1% biosurfactant, 40% cottonseed oil, and 2% hydroxyethyl cellulose, achieved the best results. The formulation exhibited both stability and emulsifying capacity (100% of petroleum). The ecotoxicity tests revealed the safety of the natural detergent. The detergent achieved satisfactory oil dispersion and solubilised 98% of the oil impregnated on the rock. The results indicate that the natural detergent holds promise for efficiently cleaning up environmental areas contaminated with oil and petroleum products.

This work describes the production of a novel biosurfactant produced by the bacterium Bacillus invictae UCP1617 cultivated using an alternative substrate and its use in the formulation of an eco‐friendly detergent. A factorial design was used to optimize agitation, temperature, and inoculum size in a mineral medium containing 1.5% corn steep liquor in 100‐mL shake flasks. The best conditions (175 rpm, 28°C, and 4% inoculum) were used to scale up biosurfactant production in a 50‐L bioreactor. Surface tension of the fermentation medium decreased from 69.5 to 30.2 mN/m within 72 h. The biosurfactant exhibited a critical micelle concentration (CMC) of 0.900 ± 0.08 g/L. The biosurfactant formed stable oil‐in‐water emulsions of motor oil and petroleum, achieving emulsification indices of 90.80% and 99.00%, respectively. An eco‐friendly detergent was formed that included biosurfactant at several different concentrations, 0.2 (wt) % hydroxyethyl cellulose and 0.2% potassium sorbate. The detergent remained stable under extreme conditions of pH, temperature, and salinity when stored for 90 days. The detergent was nontoxic to cabbage, cherry tomato plants, and the microcrustacean Artemia salina. A detergent formulation containing biosurfactant at the CMC completely dispersed motor oil in seawater at a 1:1 surfactant/oil (vol/vol) ratio and removed 99.21% of motor oil (20 mL) contained in 60 g of clayey soil. The detergent removed 98.42% of the oil adhered to a glass surface and removed 75.00% of motor oil adsorbed to a porous surface. The application of this biosurfactant as an environmentally friendly additive for remediation processes is feasible.
