Czapek‑Dox Broth — Semi‑Synthetic Medium 
CAT: AS‑1189
 
Overview
Czapek‑Dox Broth (CAT: AS‑1189) is a semi‑synthetic liquid medium designed for the cultivation of fungi that utilize inorganic nitrogen sources, particularly Aspergillus, Penicillium, and non‑sporulating molds. Using sodium nitrate as the sole nitrogen source and sucrose as the sole carbon source, this broth provides a defined nutrient environment for selective fungal studies, microbial differentiation, and physiological investigations.
Applications
Cultivation of Aspergillus and Penicillium species.
Growth of non‑sporulating molds.
Soil microbiology and environmental fungal studies.
Fungal physiology and morphology research.
Key Features
Defined nutrient composition: supports growth of fungi utilizing inorganic nitrogen.
Selective carbon/nitrogen sources: sucrose and sodium nitrate promote fungal growth while limiting bacterial overgrowth.
Liquid format: ideal for suspension cultures and physiological studies.
Versatile applications: suitable for environmental microbiology, fungal physiology, and differentiation assays.
