Used as a selective growth medium for cultivating fungi, especially species of Aspergillus and Penicillium. It supports the development of characteristic reproductive structures that aid in morphological identification. Commonly used in environmental monitoring, food and pharmaceutical testing, and agricultural research to isolate and study soil-borne fungi. Its low nutrient content helps suppress bacterial growth, making it suitable for isolating fungi from mixed samples. Also employed in physiological studies involving nitrate utilization and carbon source metabolism in fungi.
