Dixon’s Agar, Modified

Lipid-Enriched Medium for Isolation and Cultivation of Malassezia Species

Dixon’s Agar, Modified is a specialized enriched medium developed for the primary isolation, cultivation, and maintenance of lipophilic yeasts, especially Malassezia furfur and related Malassezia species. Its malt extract base and added lipid components provide the fatty nutritional environment required for recovery of these fastidious skin-associated yeasts.

AS-1210 Malassezia Culture ✓ Lipid-Enriched Clinical Mycology

🧫 Designed for lipophilic yeasts 🧪 Tween 40 + glycerol mono-oleate support 🔬 Useful for skin mycology workflows

🏆 Malassezia Recovery Medium

🦠 Primary isolation of Malassezia

⚗️ Lipid supplementation for fastidious strains

📋 COA + SDS available

🩺 Suitable for dermatology and clinical mycology labs

🔬 Supports maintenance and subculture

Key Advantage

Provides fatty nutritional support absent in routine fungal media

🔬 Principle of the Medium

Malassezia species are lipophilic yeasts commonly associated with sebaceous areas of human and animal skin, so in vitro growth requires media supplemented with natural oils or other fatty substances. Modified Dixon’s Agar addresses this by combining a rich malt extract–peptone base with lipid supplements such as Tween 40 and glycerol mono-oleate. The acidic pH also favors fungal growth while helping suppress contaminating bacteria.

            ↓

            Supports growth of lipophilic Malassezia spp.

🧬 Applications

🩺 Clinical Dermatology

Suitable for primary isolation of Malassezia from skin scrapings and other dermatological specimens in clinical mycology workflows.

🔬 Isolation & Maintenance

Useful not only for primary recovery but also for cultivation, maintenance, and subculture of lipophilic yeasts that grow poorly on routine fungal media.

🧫 Comparative Mycology Studies

Appropriate for laboratories comparing growth behavior of Malassezia strains against conventional yeast and mold media.

🐾 Veterinary & Research Use

Suitable for animal mycology and broader research involving warm-blooded host-associated lipophilic yeasts.

📊 Comparative Malassezia Media Guide

Medium	Primary Role	Best Use	Key Advantage
Dixon’s Agar, Modified	Enriched lipid-dependent fungal medium	Primary isolation of Malassezia	Lipid-rich support for fastidious lipophilic yeasts
Sabouraud Dextrose Agar	General fungal isolation medium	Routine yeasts and molds	Broad fungal use, but less suited to strict lipid requirement
Leeming-Notman Agar	Specialized lipid-enriched medium	Malassezia culture and recovery	Alternative specialized medium for lipophilic species
Potato Dextrose Agar	General yeast and mold cultivation	Routine fungal growth	Useful broad medium, not optimized for lipid-dependent yeasts
