Description

Pediocin Ach CAS NO 120367-03-5 is a bacteriocin, a natural antimicrobial peptide produced by certain strains of *Pediococcus* bacteria. This compound is of significant commercial and research interest due to its potent inhibitory activity against a range of Gram-positive foodborne pathogens, most notably *Listeria monocytogenes*. It is primarily sought after by manufacturers and researchers in the food preservation, biotechnology, and pharmaceutical development sectors seeking natural biopreservatives and novel antimicrobial agents.

Application

• Food Biopreservation: As a natural antimicrobial agent to inhibit spoilage and pathogenic bacteria, particularly *Listeria*, in dairy products (cheese, yogurt), fermented meats, and ready-to-eat foods.
• Starter Culture Component: Incorporated into protective cultures for fermented foods to ensure process safety and consistency by outcompeting undesirable microflora.
• Pharmaceutical Research: Investigated for its potential therapeutic applications as an alternative or adjunct to conventional antibiotics, especially against drug-resistant strains.
• Veterinary and Animal Feed: Used as a feed additive to promote gut health and inhibit pathogenic bacteria in livestock, contributing to animal growth and food safety.
• Active Packaging: Integrated into food packaging films or coatings to create antimicrobial surfaces that extend product shelf life.
• Microbiological Research: Serves as a standard or model bacteriocin in studies on antimicrobial peptides, mode of action, and genetics of bacteriocin production.

Quality Control

Our Pediocin Ach is produced and purified under controlled conditions to ensure high activity and batch-to-batch consistency. Quality is assured through rigorous analytical testing, including potency assays against target microorganisms, purity assessment, and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing specific activity (AU/mg), purity level, and microbiological safety is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store lyophilized (freeze-dried) material at -20°C or below. Reconstituted solutions should be aliquoted and stored at -80°C to minimize activity loss. The product is hygroscopic (moisture-sensitive); ensure containers are sealed tightly after each use to prevent moisture uptake.
