Description

Helveticin J CAS NO 104708-98-7 is a bacteriocin, a ribosomally synthesized antimicrobial peptide, produced by certain strains of *Lactobacillus helveticus*. This compound is significant for its targeted antimicrobial activity, offering a natural alternative to traditional chemical preservatives in sensitive applications. It is primarily sought by manufacturers in the food & beverage and pharmaceutical industries for biopreservation and research into novel antimicrobial agents.

Application

• Food Biopreservation: Used to inhibit spoilage and pathogenic bacteria in dairy products, fermented foods, and ready-to-eat meals, extending shelf life naturally.
• Pharmaceutical Research: Serves as a model compound in studies of novel antimicrobial mechanisms and the development of new therapeutic agents.
• Starter Culture Protection: Employed in fermentation processes to protect desirable bacterial cultures from phage infections and competitive microbial flora.
• Dairy Industry: Applied in cheese and yogurt production to control specific non-starter lactic acid bacteria and improve product consistency and safety.
• Microbiological Media: Used as a selective agent in culture media for the isolation and identification of specific bacterial strains.
• Veterinary Applications: Investigated for use in animal feed as a growth promoter and to control gastrointestinal pathogens.
