Description

Bacteriocin A CAS NO 155870-23-8 is a potent, ribosomally synthesized antimicrobial peptide produced by certain strains of bacteria. This compound matters for its targeted bactericidal or bacteriostatic activity against closely related bacterial strains, offering a natural alternative to traditional antibiotics. It is needed by researchers in microbiology and biotechnology, as well as manufacturers in the food preservation and pharmaceutical industries for developing novel antimicrobial agents and biopreservatives.

Application

• Food Preservation & Safety: Used as a natural biopreservative to inhibit spoilage and pathogenic bacteria in dairy products, meats, and fermented foods, extending shelf life.
• Pharmaceutical Research: Serves as a lead compound or model for developing new classes of narrow-spectrum antibiotics and therapeutic peptides.
• Microbiological Studies: Employed in laboratory research to study bacterial competition, quorum sensing, and mechanisms of antimicrobial action.
• Agricultural Applications: Explored for use in animal feed additives to promote gut health and as a plant protection agent against bacterial diseases.
• Cosmetic Formulations: Investigated for incorporation into personal care products for its potential antimicrobial properties against skin-related bacteria.
• Starter Culture Enhancement: Used in the production of fermented foods to improve the competitiveness and efficacy of desirable starter cultures.

Quality Control

Our Bacteriocin A is produced and handled under stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and biological activity. Certificates of Analysis (COA) detailing specifications such as potency (AU/mg), purity by HPLC, and microbiological assay results are available upon request to support your research and development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This hygroscopic (moisture-sensitive) material should be handled under dry, inert conditions to maintain potency. Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation.
