Exploration of quorum quenching Lactobacillus sp. for controlling biofilm forming bacteria causing spoilage of dairy products

Limosilactobacillus fermentum UAS LAB 6 is a lactic acid bacterium isolated from raw cow milk during a study on quorum-quenching and biofilm inhibition in dairy-associated microorganisms. This strain exhibits potential to interfere with quorum sensing in spoilage bacteria such as Pseudomonas fluorescens, thereby contributing to improved milk quality and shelf life. Whole genome sequencing of UAS LAB 6 provides insights into its genetic basis for quorum-quenching activity, antimicrobial potential, and suitability as a safe bioprotective culture in dairy applications.
