Used primarily in microbiology for the selective isolation and differentiation of fungi and yeasts from clinical and non-clinical samples. The medium contains rose bengal dye, which primarily inhibits bacterial growth and limits the spread of mold colonies, allowing slower-growing fungal species to be isolated more effectively. It is commonly employed in environmental monitoring, food testing, and clinical diagnostics to assess fungal contamination. Due to its selective properties, it helps reduce overgrowth of unwanted microorganisms, improving the recovery of target organisms like Candida and Aspergillus species. Often used in conjunction with other culture media for comprehensive microbial analysis.
