【 Principle 】

Peptone provides an organic nitrogen source and is rich in peptides, amino acids, vitamins, and trace growth factors; Glucose is the main carbon and energy source for fungi; Potassium dihydrogen phosphate serves as a pH buffer to stabilize the pH of the culture medium and maintain an acidic and alkaline environment suitable for fungal growth; Sodium chloride maintains the osmotic pressure of the culture medium; Magnesium ions, as activators of various key enzymes, participate in sugar metabolism, nucleic acid synthesis, and redox reactions, maintaining enzyme activity and normal physiological functions of fungi, thereby promoting stable fungal growth.

Main components

Composed of peptone, glucose, dipotassium hydrogen phosphate, sodium chloride, magnesium sulfate, and distilled water.

Storage conditions and expiration date

Storage conditions: This product should be stored in a dark environment at 2-8 ℃.

Validity period: The unopened original packaging has a validity period of 6 months.

This product is a disposable product.

Clinical specimen testing: Isolation and cultivation of fungi and yeast from clinical samples such as sputum, secretions, and urine to assist in the diagnosis of fungal infections.

Aseptic product inspection: used for mold contamination inspection of sterile drugs, biological products, medical equipment, and dressings to determine whether the product is qualified.

Hospital environmental monitoring: Sampling of operating rooms, wards, clean areas, workstations, and air to monitor the distribution of mold and prevent and control nosocomial infections.

Hygiene sample screening: Conduct mold counting and contamination testing on samples such as drinking water, purified water, and food.

Strain cultivation and identification: used for the recovery, passage and preservation of fungal standard strains, as well as the purification and morphological identification of clinically isolated strains.

Infection tracing analysis: When a cluster of fungal infections occurs, sample, culture, and inspect the environment and items to trace the source of infection.

Penicillium genus

Mycelium has transverse septa; The conidiophores have typical broom shaped branches, and the conidia are arranged in a string like pattern; Specialized aerobic; Resistant to weak acids, strong environmental adaptability, and vigorous growth state.

Aspergillus genus (Aspergillus niger, Aspergillus flavus, Aspergillus fumigatus)

Mycelium has transverse septa; The conidiophores stand upright, with their tips expanding into apical sacs, forming characteristic conidiophore heads; There are significant differences in colony color among different bacterial strains; Specialized aerobic; Prefer weakly acidic environments; Strong growth ability and stable reproduction; Some strains can synthesize fungal toxins.

Candida genus (Candida albicans, Candida tropical, Candida smooth)

The bacterial cells are round or oval in shape, and Gram staining is positive; After cultivation, false hyphae and thick walled spores can be formed; Facultative anaerobic; It has a wide temperature adaptability range and can grow well at 22-28 ℃ and 35-37 ℃; Tolerant to weakly acidic environments.
