Agar is widely used in microbiology as a solidifying agent for culture media, providing a stable surface for the growth of bacteria, fungi, and other microorganisms. It is also employed in the food industry as a gelling, thickening, and stabilizing agent in products like desserts, jellies, dairy items, and ice creams. In molecular biology, agar serves as a medium for gel electrophoresis to separate DNA, RNA, or proteins based on size. Additionally, it is used in plant tissue culture to support plant growth under sterile conditions. Its biocompatibility and non-toxic nature make it suitable for pharmaceutical applications, such as in laxatives and capsule formulations. Agar is also utilized in the cosmetics industry as a thickener in creams, lotions, and other personal care products to improve texture and provide moisturizing effects.
