Used primarily in microbiology for the cultivation and enumeration of heterotrophic bacteria in water, food, and environmental samples. Supports the growth of slow-growing and stressed microorganisms due to its low nutrient content, making it ideal for recovering bacteria from chlorinated and treated water systems. Commonly used in pharmaceutical, drinking water, and wastewater testing to assess microbial quality and ensure compliance with safety standards. Also employed in biofilm studies and in monitoring microbial populations in industrial water systems.
