Description

Peptone, Fish Powder is a high-quality, water-soluble protein hydrolysate derived from fish sources, serving as a premium source of organic nitrogen, peptides, and amino acids. This product is essential for providing the complex nutritional foundation required for robust microbial and cell growth in industrial fermentation and biotechnology processes. It is a critical raw material for manufacturers in the microbiology, pharmaceutical, and diagnostic industries seeking consistent and reliable culture media components.

Application

• Microbiological Culture Media: A fundamental nitrogen source for the preparation of nutrient broths, agars, and selective media for bacterial and fungal cultivation.
• Fermentation Processes: Used as a complex nutrient to enhance biomass yield and metabolite production (e.g., enzymes, antibiotics, vitamins) in industrial bioreactors.
• Vaccine and Biologics Production: Employed in cell culture media for the growth of cells used in vaccine manufacturing and other biopharmaceutical applications.
• Diagnostic Reagents: A key ingredient in formulations for diagnostic tests and kits that rely on microbial growth or enzymatic activity.
• Enzyme Production: Stimulates the synthesis of proteolytic and other industrial enzymes by providing essential amino acids and growth factors.
• Research & Development: Utilized in laboratories for microbiological research, strain development, and quality control testing.

Quality Control

Our Peptone, Fish Powder is manufactured and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for microbiological purity, chemical composition, and performance consistency. Certificates of Analysis (COA) documenting parameters such as total nitrogen, amino nitrogen, solubility, pH, and bioburden are available upon request to support your quality assurance protocols.

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); the container must be kept tightly sealed after each use to prevent caking and degradation due to moisture absorption.
