【 Principle 】

Peptone provides organic nitrogen sources, peptides, amino acids, and trace growth factors; Glucose is the main carbon and energy source for fungi; Magnesium sulfate dissociates magnesium ions, which act as activators for various metabolic enzymes, participate in sugar metabolism and nucleic acid synthesis, maintain fungal physiological activity, and promote stable growth; Sodium dihydrogen phosphate is used as a pH buffer to stabilize the culture medium and maintain a weakly acidic environment.

Main components

Composed of peptone, sodium dihydrogen phosphate, magnesium sulfate, glucose, and distilled water.

Candida albicans

Gram staining is positive, and the yeast cells are round or oval in shape. During the cultivation process, pseudohyphae and thick walled spores can be formed; Belonging to facultative anaerobic microorganisms; It has a wide temperature adaptability range and can grow and reproduce well under conditions of 22-28 ℃ and 35-37 ℃.

Tropical Candida and Smooth Candida

It mainly exists in the form of yeast cells, and some strains can produce pseudohyphae; The growth characteristics such as physiological metabolism and temperature adaptability are similar to those of Candida albicans.

Aspergillus genus (Aspergillus niger, Aspergillus flavus)

Mycelia have septa and can form typical morphological conidiophores; For specialized aerobic microorganisms; Prefers a weakly acidic environment and has strong self growth ability.
