Bacteriocin producing strain added to the NCIMB culture collection

A Bacteriocin-producing strain isolated from human milk is now available from the National Collection of Industrial, Food and Marine Bacteria. NCIMB 15251 Lactobacillus gasseri was isolated from human milk and deposited at NCIMB by scientists from the Department of Gut Microbes and Health at the Quadram Institute.  The strain produces several bacteriocins including a novel bacteriocin, gassericin M. Bacteriocins are antimicrobial peptides produced by bacteria, which are of interest with respect to probiotics.

NCIMB manages the National Collection of Industrial, Food and Marine Bacteria – a reference collection of ACDP hazard group 1 and 2 microorganisms that includes many environmentally important and industrially useful bacteria, plasmids and bacteriophages. The collection is continuously expanding due to new accessions from the international research community.

The gut microbiome and its relationship to human health is a very exciting area of research and we are delighted to be able to reflect the current levels of interest in the topic with new additions to our culture collection.  For more information about our culture collection visit our culture collection webpages or contact
