“…For the dispersant activity of motor oil, slight activations are observed at concentrations ranging from 0.5 to 4% NaCl. These results are similar to numerous previous work reporting the stability of the surface activities of biological surfactants after pre-incubation in the presence of decreasing NaCl concentration (Chen et al 2017, Feng et al 2019, Ghazala et al 2017, Kiran et al 2017, Martins et al 2018, Purwasena et al 2019, Qiao &Shao 2010). This offers a broad spectrum of application of BI2 biosurfactant in the bioremediation of saline and sea waters contaminated by hydrocarbons.…”

Lipopeptides Biosurfactants are natural surface-active compounds produced by a variety of microorganisms. They have great interest in environmental, biomedical and agro-industrial fields. However, the high cost of culture media and the low yield of production limit their large-scale production and application. The development of efficient and cost-effective bioprocess became of a great interest for the improvement of the yield of biosurfactants and the decrease of production cost. In this aim, we applied the response surface method to optimize an economic biosurfactant production by a newly isolated strain B. mojavensis BI2 on date syrup called “Luegmi” as unique carbon and nitrogen source. Using a Box-Bhenken design, we studied the effect of three independent variables on lipopeptide production; Leugmi concentration, Na 2 HPO 4 and incubation time. The results of this study showed that Leugmi concentration at 25%, Na 2 HPO 4 at 0.1% and incubation time of 24 hours were optimal conditions for biosurfactant production, with a maximum surface tension decreasing capacity of 55% corresponding to 27 mN/m and oil dispersing of 30 cm 2 corresponding to a diameter of 6 cm. Preliminary characterization of the biosurfactant produced on Luegmi by UV-Spectra and Thin Layer Chromatography showed its lipopeptide characters. Physic-chemical characterization of the produced lipopepetide on Leugmi showed its great surface activities and stabilities at different pH, temperature and salts concentration. The results of this study suggested that Leugmi, an agricultural byproducts can be used as a low-cost substrate to enhance the yield of lipopeptide biosurfactants with great surface activities for potential environmental application.

“…Conventional methods require the application of dispersants (with complex additives, including surfactants) to form fine droplets out of oil slicks and oil-in-water emulsion from mousse oil [103]. However, these chemical dispersants are toxic to various aquatic lives and are hardly biodegradable [104]. Thus, an eco-friendly, biodegradable, and effective dispersant is required.…”

“…Besides, biosurfactants produced from Ralstonia picketti and Alcaligenes piechaudii have also proved effective in the degradation of hydrocarbons by up to 80% [110]. Another study by Feng et al [104] recorded a dispersant effectiveness of lipopeptide produced by Bacillus subtilis HSO1121 at a low surfactant:oil ratio. Besides, the biosurfactant excellently stimulated microbial oil degradation.…”

Surfactants are a broad category of tensio-active biomolecules with multifunctional properties applications in diverse industrial sectors and processes. Surfactants are produced synthetically and biologically. The biologically derived surfactants (biosurfactants) are produced from microorganisms, with Pseudomonas aeruginosa, Bacillus subtilis Candida albicans, and Acinetobacter calcoaceticus as dominant species. Rhamnolipids, sophorolipids, mannosylerithritol lipids, surfactin, and emulsan are well known in terms of their biotechnological applications. Biosurfactants can compete with synthetic surfactants in terms of performance, with established advantages over synthetic ones, including eco-friendliness, biodegradability, low toxicity, and stability over a wide variability of environmental factors. However, at present, synthetic surfactants are a preferred option in different industrial applications because of their availability in commercial quantities, unlike biosurfactants. The usage of synthetic surfactants introduces new species of recalcitrant pollutants into the environment and leads to undesired results when a wrong selection of surfactants is made. Substituting synthetic surfactants with biosurfactants resolves these drawbacks, thus interest has been intensified in biosurfactant applications in a wide range of industries hitherto considered as experimental fields. This review, therefore, intends to offer an overview of diverse applications in which biosurfactants have been found to be useful, with emphases on petroleum biotechnology, environmental remediation, and the agriculture sector. The application of biosurfactants in these settings would lead to industrial growth and environmental sustainability.
