Abstract
Official abstract text for this publication.
The present invention refers to a strain of Lactobacillus curvatus bacteria deposited in the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmBH (DSMZ) under thew accession number DSM 18775, as well as to compositions, cultures and food products comprising thereof. The strain of the invention is useful for preserving food products, especially under refrigerated conditions.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for preparing a composition capable of inhibiting the growth of at least one food-borne pathogenic bacterium said process comprising: (a) culturing cells of Lactobacillus curvatus deposited in the Deutsche Sammlung von Mikroorganismen and Zellkulturen GmbH under accession number DSM 18775 in a culture medium to produce a bacteriocin that has inhibitory activity against the at least one food-borne pathogenic bacterium; and (b) separating a supernatant comprising the bacteriocin from the cultured cells to obtain a composition comprising the bacteriocin. 2. The process according to claim 1 , which further comprising subjecting the composition to a drying step to obtain a dried product comprising the bacteriocin. 3. The process according to claim 2 , wherein the drying step is freeze drying or spray drying. 4. The process according to claim 1 , wherein effective amounts of the composition have a bacteriocidal effect on the at least one food-borne pathogenic bacterium. 5. The process according to claim 1 wherein the at least one food-borne pathogenic bacterium is Listeria monocytogenes.
