Czapek-Dox Broth and Czapek Solution Agar are used for cultivating fungi and bacteria capable of using inorganic nitrogen.

• Saccharose is the sole carbon source
• Sodium nitrate is the sole nitrogen source
• Dipotassium phosphate is the buffering agent
• Potassium chloride contains essential ions
• Magnesium sulfate and ferrous sulfate are sources of cations
• Agar is the solidifying agent in Czapek Solution Agar

Czapek-Dox media are useful in a variety of microbiological procedures, including soil microbiology and fungi and mildew resistance tests. These media produce moderately vigorous growth of most saprophytic aspergilli and yield characteristic mycelia and conidia.
