Description

Bacto-Peptone is a high-quality enzymatic digest of protein, widely recognized as a premium nitrogen source for microbiological culture media. Its consistent composition and high nutritional value are critical for supporting robust and reproducible microbial growth in research and industrial fermentation processes. This product is essential for manufacturers and laboratories in the pharmaceutical, biotechnology, and diagnostic sectors requiring reliable media components for cell culture, vaccine production, and microbial testing.

Application

• As a primary nitrogen source in the formulation of complex and defined microbiological culture media.
• For the cultivation of bacteria, yeast, and fungi in academic, industrial, and clinical research laboratories.
• In vaccine production processes, including the growth of viral substrates and bacterial antigens.
• As a key ingredient in fermentation broths for the industrial production of enzymes, antibiotics, and other metabolites.
• For use in diagnostic media for the isolation and identification of pathogenic microorganisms.
• In cell culture applications, serving as a supplement for hybridoma and other mammalian cell lines.
• For quality control and sterility testing within pharmaceutical manufacturing environments.

Quality Control

Our Bacto-Peptone is manufactured and tested to meet the stringent requirements for microbiological culture applications. Each batch undergoes rigorous quality testing to ensure compliance with industry standards for nitrogen content, clarity of solution, growth promotion, and absence of inhibitory substances. Certificates of Analysis (COA) detailing specifications for purity, microbiological bioburden, and endotoxin levels (where applicable) are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is securely sealed after each use to prevent absorption of atmospheric moisture, which can affect performance and stability.
