Description

Plantaricin A CAS NO 131463-18-8 is a potent, naturally occurring antimicrobial peptide (bacteriocin) produced by certain strains of *Lactobacillus plantarum*. This compound matters for its highly specific activity against Gram-positive bacteria, including foodborne pathogens and spoilage organisms, making it a valuable tool for natural preservation. It is needed by manufacturers in the food and beverage industry seeking clean-label biopreservatives, as well as by researchers in microbiology and pharmaceutical development exploring novel antimicrobial agents.

Application

• Food Biopreservation: Used to inhibit spoilage bacteria and pathogens like *Listeria* in dairy products, fermented meats, and ready-to-eat foods, extending shelf life naturally.
• Starter Culture Enhancement: Employed in probiotic and fermented food production to improve the competitive edge of desirable lactic acid bacteria.
• Pharmaceutical Research: Serves as a lead compound or model for developing new antimicrobial peptides and therapeutic agents.
• Animal Feed Additive: Investigated as a potential alternative to traditional antibiotics in feed for promoting gut health and growth performance.
• Microbiological Studies: Utilized as a standard or tool in research on bacteriocin mode of action, resistance mechanisms, and bacterial competition.
• Cosmetic Preservation: Explored for use in personal care products as a natural preservative system against skin microbiota.

Quality Control

Our Plantaricin A is produced and handled under strict quality protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and biological activity. Certificates of Analysis (COA) detailing specifications such as purity by HPLC, peptide content, and antimicrobial activity units are available upon request. We adhere to relevant quality management standards to ensure supply reliability for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For short-term use, store at 2-8°C.
