BIOSURFACTANTS OF MARINE MICROORGANISMS: ІІІ. APPLICATIONS IN INDUSTRIAL TECHNOLOGIES

Summary Surface-active compounds (SAC) and emulsifiers, due to their ability to reduce interfacial tension, are widely used in various industries. Most of the SAC used today are produced from non-renewable petrochemical raw materials and are not safe for living beings and the environment. Biosurfactants (BS) are synthesized by microorganisms from renewable raw materials, in particular, from food industry waste, they are a promising alternative to chemical surfactants due to their biological transformation and environmental friendliness. The advantage of BS produced by marine microbiota is that they exhibit their activity over a wide range of temperatures, pH and salinity. It is shown that these biosurfactants, in addition to surface-active properties, often have other types of activity: antimicrobial, antibiofilm, antioxidant. It has been established that biosurfactants of marine microorganisms can be widely used in industries such as the production of hygiene products, pharmaceuticals, cosmetology, food industry, agriculture, bioremediation, and oil production.
