Description
Casein Peptone Tryptone Powder is a premium water-soluble protein hydrolysate produced through controlled enzymatic tryptic digestion of high-purity bovine casein. Specially formulated for microbiological culture and biotechnological research, this refined light yellow fine powder serves as a core organic nutrient ingredient for microbial growth media. It features excellent solubility, stable chemical properties and rich nutritional components, fully complying with standard microbiological grade specifications to meet laboratory analysis and industrial production requirements.
Core Nutritional Characteristics
This product is a superior source of organic nitrogen, free amino acids, small molecular peptides, vitamins and trace minerals. With a balanced and easily absorbable nutritional system, it effectively supplies essential nutrients for microbial cell proliferation and metabolic synthesis. Its moderate pH value (6.7–7.7 for 5% aqueous solution) adapts to the optimal growth environment of most microorganisms, avoiding growth inhibition caused by pH imbalance. The standardized total nitrogen content ensures stable and consistent nutritional supply, greatly improving the reproducibility of microbial culture experiments.
Key Advantages
1. Wide Applicability: Supports the robust growth of a broad spectrum of microorganisms, including fastidious and heterotrophic bacteria, yeasts, molds and other fungi, covering conventional microbial culture and isolation scenarios.
2. High Purity & Stability: Strict production process eliminates impurity interference, with low moisture content and uniform powder texture. It maintains stable nutritional activity during long-term storage and avoids deterioration or failure of culture media.
3. Excellent Solubility: Dissolves rapidly and completely in water without precipitation or turbidity, ensuring the clarity and uniformity of prepared culture media, which is conducive to microbial observation and counting.
4. Standardized Quality: Manufactured in strict accordance with microbiological reagent standards, with stable batch-to-batch consistency, suitable for standardized laboratory testing and large-scale industrial fermentation production.
Main Applications
Widely applied in preparation of general microbial culture media, selective media and differential media. It is commonly used for microbial isolation, purification, cultivation and identification in microbiological laboratories. In addition, it is an essential nutritional additive for industrial fermentation, antibiotic production, biological vaccine research and development, and biochemical engineering projects, serving academic research, pharmaceutical biology, food safety testing and environmental microbial detection fields.
Storage & Usage Notes
Seal and store in a dry, cool and well-ventilated environment, away from moisture, high temperature and direct sunlight. Avoid repeated opening and closing to prevent moisture absorption and microbial contamination. It is recommended to use it within the validity period to ensure optimal nutritional performance and experimental accuracy.
