Selectively cultivate, isolate, and enumerate yeasts and molds from environmental and food specimens with Thermo Scientific™ Remel™ Contact I Rose Bengal Agar (with chloramphenicol). Smith and Dawson added rose bengal to a medium with neutral pH for selective isolation of fungi from soil samples¹. Rose Bengal Agar with chloramphenicol is based on the formula developed by Jarvis for enumeration of yeasts and molds from food and water^2,3.

Selectively cultivate, isolate, and enumerate yeasts and molds using selective medium Contact I Rose Bengal Agar (with chloramphenicol).

• Ready-to-use – Contact plates. Convenience of prepared media.
• Selective – Chloramphenicol is the selective agent which inhibits bacterial growth.
• Easy-to-interpret – Cells of yeasts and molds absorb the rose bengal dye turning colonies color to pink, which makes the identification of the yeasts and molds easier.

Contact I Rose Bengal Agar (with chloramphenicol) contains dextrose as the fermentable carbohydrate and a ready source of energy. Soy peptone supplies nitrogen and vitamin sources required for the growth of fungi. Chloramphenicol is added as a selective agent because of its heat stability and broad-spectrum antibacterial activity. Monopotassium phosphate is a buffer and magnesium sulfate provides sulfate and other trace elements. Rose bengal is an indicator and also acts as a selective agent which inhbits the growth of bacteria and limits the size of faster-growing molds. This helps to detect the slower-growing yeasts.
