Czapek Dox Agar: Cultivation Medium for Fungi

CAT No.: AS-1188

Product Description: Czapek Dox Agar, also known as Czapek’s agar (CZA) or Czapek-Dox medium, is a growth medium designed for propagating fungi and other organisms in laboratory settings. This semisynthetic medium contains sodium nitrate as the sole source of nitrogen and sucrose as the only source of carbon. It is highly recommended for use in qualitative procedures for the cultivation of saprophytic fungi, soil bacteria, and other microorganisms.

Originally developed by Czapek in 1902 for the cultivation of saprophytic fungi, Czapek-Dox Agar is a modification of the Czapek (1902-1903) and Dox (1910) formula, prepared according to Thom and Church. The medium is also suitable for chlamydospore production by Candida albicans. The inclusion of various salts provides good buffering action, ensuring an optimal growth environment.

Key Features:

  • Optimal Nutrient Composition: Contains sodium nitrate and sucrose, providing essential nutrients for the growth of fungi and other microorganisms.

  • Buffering Action: The presence of various salts ensures good buffering capacity, maintaining a stable pH for optimal growth.

  • Versatility: Suitable for the cultivation of saprophytic fungi, soil bacteria, and other microorganisms, as well as chlamydospore production by Candida albicans.

  • Reliable Growth Support: Promotes abundant growth of almost all saprophytic Aspergilli, resulting in characteristic mycelial and conidial formation.
