Description

Peptone CAS NO 73049-73-7 is a complex enzymatic digest of animal or plant proteins, serving as a vital source of amino acids, peptides, and nitrogen. This high-quality nutrient is essential for promoting robust and consistent microbial growth in fermentation and cell culture processes. It is a critical raw material for manufacturers in the biotechnology, pharmaceutical, and diagnostic industries, where reliable and high-yield production is paramount.

Application

• Microbiological Media Formulation: A primary nitrogen source in nutrient broths, agar plates, and fermentation media for bacteria, yeast, and fungi cultivation.
• Pharmaceutical Fermentation: Used in the production of antibiotics, vaccines, enzymes, and other therapeutic proteins to support high-density cell growth.
• Vaccine Production: Provides essential nutrients for the growth of cell lines (e.g., Vero, CHO) used in viral vaccine manufacturing.
• Diagnostic Reagents: A key component in culture media for clinical microbiology, used for pathogen isolation and identification.
• Enzyme Production: Supports the growth of microorganisms in industrial-scale enzyme production processes.
• Food & Beverage Industry: Employed in starter culture preparation for dairy products, fermented beverages, and probiotics.
• Research & Development: Used in academic and industrial labs for general microbiological studies, strain development, and bioprocess optimization.

Quality Control

Our Peptone is manufactured under strict quality management systems to ensure batch-to-batch consistency and performance. Each lot undergoes rigorous testing for key parameters including total nitrogen, amino nitrogen, clarity, pH, and microbiological bioburden. Certificates of Analysis (COA) detailing these specifications are provided with every shipment. Production can be aligned with relevant standards for pharmaceutical (USP/EP), food (FCC), or industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to prevent caking and degradation.
