Principle
- Czapek Dox Broth consists of sucrose, sodium nitrate, dipotassium phosphate, magnesium sulfate, potassium chloride, and ferrous sulfate.
- Sucrose serves as the source of carbon while sodium nitrate serves as a source of nitrogen. Dipotassium phosphate buffers the medium. Magnesium sulphate, potassium chloride, and ferrous sulphate serve as sources of essential ions.
- The selectivity of the medium is increased by addition of chloramphenicol.
