Description

Peptone is a complex mixture of polypeptides and amino acids produced by the partial hydrolysis of proteins. It serves as a vital source of organic nitrogen, amino acids, and peptides, making it an essential nutrient component in microbiological and cell culture media. This product is indispensable for researchers and manufacturers in the biotechnology, pharmaceutical, and food industries who require consistent, high-quality growth substrates for fermentation, vaccine production, and diagnostic applications.

Application

• Microbiological Culture Media: A fundamental nitrogen source for cultivating a wide range of bacteria, yeasts, and fungi in laboratory and industrial fermentation processes.
• Pharmaceutical & Vaccine Production: Used in fermentation broths for the production of antibiotics, enzymes, and vaccines, providing essential nutrients for high-yield cell growth.
• Cell Culture & Biotechnology: Acts as a supplement in serum-free and complex media for mammalian and insect cell culture, supporting protein and monoclonal antibody production.
• Diagnostic Media: A key ingredient in prepared culture media for clinical microbiology, used for pathogen identification and antibiotic susceptibility testing.
• Food & Flavor Industry: Employed as a flavor enhancer and nutrient supplement in processed foods, savory flavors, and as a substrate for food-grade enzyme production.
• Enzymatic Digestion Studies: Serves as a standardized substrate for testing and calibrating proteolytic enzyme activity.

Quality Control

Our Peptone is manufactured under a quality management system and undergoes rigorous batch-by-batch testing to ensure consistency and performance. Key parameters such as total nitrogen, amino nitrogen, solubility, clarity, and microbiological bioburden are strictly controlled. A Certificate of Analysis (COA) detailing specifications and test results is provided with each shipment. Production can comply with relevant standards for industrial, food grade (FCC), or pharmaceutical 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 material is hygroscopic (moisture-sensitive); keep the container tightly sealed after opening to prevent caking and degradation due to moisture absorption.
