Special Issue Information
Dear Colleagues,
Biosurfactants are surface-active compounds produced by microorganisms such as bacteria, yeast, and fungi. They have gained significant attention due to their biodegradability, low toxicity, and environmental compatibility compared to synthetic surfactants. The production of biosurfactants involves the fermentation process, where microorganisms are cultivated in a nutrient-rich media. The choice of microorganism and medium composition, including carbon and nitrogen sources, influences the yield and properties of the biosurfactants produced. Common methods for extracting and purifying biosurfactants include solvent extraction, precipitation, and chromatographic techniques. Biosurfactants have a wide range of applications across various industries. In the petroleum industry, they can be used for microbial-enhanced oil recovery and the bioremediation of oil spills, since they significantly reduce surface and interfacial tension. In the food industry, they can be used as emulsifying agents, stabilizing blends of water and oil in products such as sauces and dressings. Biosurfactants are also valuable in the cosmetic and pharmaceutical industries, where they function as emulsifiers, foaming agents, and wetting agents in formulations such as creams, lotions, and shampoos. Additionally, in the agricultural sector, they are utilized for biocontrol against plant pathogens and in eco-friendly pesticide formulations. The versatility and sustainability of biosurfactants continue to drive research and innovation in their production and application. Therefore, this Special Issue is focused on, but not limited to, the production of biosurfactants, including yields, purification, culture medium composition, scale-up, etc.
