Description

Pediocin Pa-1 CAS NO 111745-56-3 is a highly specific and potent Class IIa bacteriocin produced by certain strains of *Pediococcus* bacteria. This compound matters for its exceptional ability to inhibit the growth of foodborne pathogens, particularly *Listeria monocytogenes*, without affecting the viability of starter cultures. It is primarily needed by manufacturers in the food and beverage industry seeking natural, targeted biopreservation solutions to enhance product safety and shelf life.

Application

• Food Biopreservation: Direct addition to dairy products (cheese, yogurt), fermented meats, and ready-to-eat foods to control *Listeria* and other Gram-positive spoilage bacteria.
• Starter Culture Enhancement: Used in conjunction with probiotic or fermentation cultures to selectively inhibit pathogens while allowing beneficial flora to thrive.
• Active Packaging: Incorporation into edible films or packaging materials to create antimicrobial surface barriers.
• Veterinary and Animal Feed: Potential application as a feed additive to promote gut health and control pathogenic bacteria in livestock.
• Research & Development: Serves as a model bacteriocin in microbiological studies, antimicrobial mechanism research, and the development of novel preservation systems.

Quality Control

Our Pediocin Pa-1 is produced and tested under stringent quality management systems. Each batch undergoes rigorous analysis to ensure high purity, potency, and activity. Specifications are aligned with food-grade material expectations. Comprehensive Certificates of Analysis (COA) detailing purity, biological activity (AU/mL or specific activity), and microbiological safety are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at 2-8°C (refrigerated) or as indicated on the label. This material is hygroscopic (moisture-sensitive); ensure the container is kept sealed in a cool, dry place to maintain stability and potency. For long-term storage, consider freezing at -20°C or below under inert atmosphere.
