The product, High Quality Peptone powder CAS 91079-38-8 With Best Price, is a high - quality peptone powder. The CAS number 91079 - 38 - 8 uniquely identifies this chemical compound. It is known for its high quality, which is reflected in its purity, consistency, and performance.
In terms of physical properties, it usually appears as a fine powder, which allows for easy dissolution and mixing with other substances. The powder is carefully processed to ensure a uniform particle size distribution, which is crucial for its stability and reactivity in various applications.
Regarding its chemical composition, peptone is a water - soluble protein hydrolysate. It is rich in various amino acids, peptides, and other nitrogen - containing compounds, which are essential for the growth and metabolism of microorganisms. The high - quality standard of this peptone powder means it has a well - balanced amino acid profile, which can effectively support the growth of a wide range of microorganisms.
This high - quality peptone powder has a wide range of uses, mainly in the field of microbiology. It is a key component in the formulation of culture media for the growth of bacteria, fungi, and other microorganisms. In laboratory settings, it is used to cultivate different strains of bacteria for research purposes, such as studying their metabolic pathways, virulence factors, and antibiotic susceptibility.
In the food industry, it can be used as a nutrient source for the fermentation process. For example, in the production of cheese, yogurt, and other fermented dairy products, peptone can promote the growth of beneficial bacteria, which helps to improve the flavor, texture, and shelf - life of the products.
It also has applications in the pharmaceutical industry. It can be used in the production of vaccines and antibiotics, as it provides the necessary nutrients for the growth of the microorganisms used in these production processes.
When using this peptone powder, it is important to follow some basic guidelines. First, for the preparation of culture media, calculate the appropriate amount of peptone powder according to the specific requirements of the microorganisms to be cultured. Usually, the concentration of peptone in culture media ranges from 0.5% to 2%.
Weigh the required amount of peptone powder accurately using a precision balance. Then, add it to the appropriate amount of distilled or deionized water. Stir the mixture well until the peptone powder is completely dissolved. It may be necessary to heat the solution gently to speed up the dissolution process, but make sure not to exceed the recommended temperature to avoid denaturing the peptone.
After dissolving the peptone, adjust the pH of the solution according to the needs of the microorganisms. Commonly, the pH of culture media is adjusted to a range of 6.8 - 7.2. Then, sterilize the culture media by autoclaving or other appropriate sterilization methods.
Case 1: A research laboratory was studying a new strain of bacteria isolated from a soil sample. They prepared a culture medium containing this high - quality peptone powder at a concentration of 1%. After inoculating the bacteria, they observed rapid growth of the bacteria within 24 hours. The bacteria reached the logarithmic growth phase earlier than when using other peptone products, which allowed the researchers to conduct their experiments on the metabolic activity of the bacteria more quickly.
Case 2: A food company was producing a new type of yogurt. They added this peptone powder to the milk before fermentation at a concentration of 0.8%. The result was a yogurt with a smoother texture, a more intense flavor, and a longer shelf - life. The addition of peptone promoted the growth of lactic acid bacteria, which led to better acidification and more effective inhibition of spoilage microorganisms.
Case 3: A pharmaceutical company was producing an antibiotic. They used this peptone powder in the culture medium for the growth of the antibiotic - producing bacteria. The high - quality peptone provided a rich nutrient source, which resulted in a higher yield of the antibiotic. The bacteria grew more vigorously, and the production process was more efficient compared to using lower - quality peptone products.
