“…The best results were observed for the biosurfactant/oil ratio of 1: 1 (v/v) for all times tested, with dispersion rates above 50%. The performance of this test demonstrates the ability of the biosurfactant to reduce the effects of large oil spills, since the dispersion of the oil in small droplets increases the exposure surface of the contaminant, facilitating its degradation by indigenous microorganisms [3,19,44]. Soares da Silva et al [45] used the Swirling Bottle technique to apply a formulated and isolated microbial surfactant in an oily effluent.…”

Contamination by oil and its derivatives causes serious damage to the environment, motivating the development of innovative technologies for the removal of these contaminants, such as the use of biosurfactants. In the present study, the biosurfactant from Candida tropicalis UCP0996 produced in the low cost-medium formulated with molasses, residual frying oil, and corn steep liquor, was characterized and its toxicity, formulation, and application in removal and biodegradation of oil were investigated. The surface tension of the medium was reduced to 30.4 mN/m, yielding 4.11 g/L of isolated biosurfactant after 120 h. Tests under extreme environmental conditions indicated the stability of the biosurfactant. Chemical characterization by thin layer chromatography (TLC), Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance (1H NMR), and gas chromatography and mass spectroscopy (CG-MS) revealed the glycolipidic nature of the biosurfactant. The isolated biosurfactant showed no toxicity against the microcrustacean Artemia salina, while the properties of the formulated biosurfactant remained stable during 120 days of storage. The biosurfactant removed 66.18% of motor oil adsorbed in marine stones and dispersed 70.95% of oil in seawater. The biosurfactant was also able to increase by 70% the degradation of motor oil by seawater indigenous microorganisms, showing great potential to be applied as a commercial additive in the bioremediation of oil spills.

“…A number of restoring technologies including biological and physico-chemical processes are available to reduce petroleum hydrocarbon concentrations in the environment (Sannino and Piccolo, 2013). Significant attention has been given to bioremediation, that mainly relies on the use of organisms with specific metabolic abilities in order to remove or minimize the toxic effect of organic and inorganic pollutants (de Almeida et al, 2017). Certainly, biological remediation is considered as an efficient approach to cleanup petroleum contaminated soils (Tiralerdpanich et al, 2018).…”

“…Depending on the characteristics of their molecule, surfactants can reduce surface tension and solubilize water in oil or oil in water since these molecules have a hydrophilic part and a hydrophobic part, allowing water encapsulation within an oily substance or vice versa, forming a structure known as amphiphilic [63,64].…”

“…Low molecular weight biosurfactants have the ability to reduce surface tension efficiently, while higher molecular weight biosurfactants are commonly used for stabilizing oil-water emulsions [65]. Biosurfactants such as proteins, lipoproteins, polysaccharides, and lipopolysaccharides, which are of high molecular weight, are commonly referred to as emulsifiers [79], while the low molecular weight ones, which include glycolipids, lipopeptides, and phospholipids, are considered the classic biosurfactants [63].…”

Population growth and the need for increased agricultural productivity pose a global problem. Therefore, the development of green compounds to ensure agricultural sustainability becomes an urgent necessity. Surfactant compounds hold significant commercial importance due to their diverse industrial uses. However, the synthetic origin of these agents limits their commercial application due to their toxicity. As a result, extensive research has focused on the production of microbial-originated green surfactants, known as biosurfactants, over the past fifteen years. These biomolecules not only offer a green alternative for agriculture but also exhibit reduced toxicity and excellent stability under specific environmental conditions. Biosurfactants can lower surface tension more effectively than synthetic surfactants. With properties such as detergency and foam formation, biosurfactants are suitable for various agricultural applications, particularly in pesticide and agrochemical formulations. They can function as biopesticides to manage pests, pathogens, phytopathogenic fungi, and weeds due to their antimicrobial activity. Moreover, plants can benefit from biosurfactant molecules and the microorganisms as nutrients. They can also aid efficiently in the distribution of micronutrients and metals in the soil. They also stimulate plant immunity and are utilized for soil hydrophilization to ensure proper moisture levels and uniform fertilizer distribution. This review aims to provide valuable insights into the role and properties of biosurfactants as agricultural adjuvants, fostering the development of sustainable formulations to replace chemical surfactants used in pesticides.
