Description

Peptones, Gelatin is a complex enzymatic digest of gelatin, serving as a vital source of amino acids, peptides, and nitrogen for microbial and cell culture systems. This product is essential for providing the necessary nutrients to support robust growth and high yields in fermentation and bioprocessing applications. It is a critical raw material for manufacturers in the pharmaceutical, biotechnology, diagnostic, and food microbiology industries who require consistent, high-quality growth media components.

Application

• Microbiological Culture Media: A fundamental nitrogen source for the preparation of nutrient broths, agars, and selective media for bacteria, yeast, and fungi.
• Pharmaceutical Fermentation: Used as a growth promoter in the large-scale production of antibiotics, vaccines, enzymes, and other therapeutic proteins.
• Cell Culture & Vaccine Production: Provides essential nutrients in serum-free or low-serum media formulations for mammalian and insect cell culture, including vaccine development.
• Diagnostic Reagents: A key ingredient in culture media for clinical diagnostics, pathogen detection, and sterility testing.
• Enzyme Production: Serves as an inducer and nutrient substrate in fermentation processes for industrial enzyme manufacturing.
• Food & Beverage Testing: Used in media for quality control, shelf-life studies, and detection of spoilage organisms or pathogens in food products.
