💡 Extracellular Polymeric Substances (EPS) from Microalgae ✅ EPS are natural polymers of high molecular weight secreted by microorganisms into their environment. ✅ These compounds are found in the matrix of other microbial biofilms such as microalgal biofilms. ✅ Microalgal EPS has similar components to the bacterial one; it is made up of proteins, phospholipids, polysaccharides, nucleic acids, humic substances, uronic acids, and some functional groups, such as phosphoric, carboxylic, hydroxyl and amino groups. ✅ Several factors contribute to the composition of EPS including species, substrate type, nutrient availability, temperature, pH and light intensity. ✅ They play crucial roles in the survival and growth of microalgae. ✅ Their biodegradability, low toxicity, and diverse functionalities make them attractive for a wide range of applications: 🌟 Biotechnological applications: EPS from microalgae can be used as biofertilizers, biostimulants... 🌟 Environmental benefits: EPS from microalgae play key roles in environmental processes such as biofilm formation, nutrient cycling, and pollutant remediation. They can also improve soil structure and water retention, making them valuable for sustainable agriculture. 🌟 The potential of EPS from microalgae extends to various industries, including food, cosmetics, and pharmaceuticals. These compounds are being explored for their role in drug delivery systems, wound healing, and as natural thickeners in food products. #Microalgae #EPS #Biotechnology #Sustainability #EnvironmentalScience Figure : Physiology of microalgal biofilm: a review on prediction of adhesion on substrates.
