| Abstract | Among lactic acid bacteria (LAB) isolated from mustard leaf kimchi, MLK27 was the most efficient strain in terms of adhesion to HT-29 cells. Competitive, exclusive, and displaceable inhibition of Listeria monocytogenes KCTC 3569 adhesion by LAB was strain-dependent. MLK27 strain displayed the highest adhesion inhibition against L. monocytogenes and produced organic acids, hydrogen peroxide, and bacteriocin. Cell-free culture supernatants (100 μL/mL) and bacteriocin (1,280 AU/mL) of MLK27 strain strongly inhibited viable cell counts of L. monocytogenes adhered to HT-29 cells. However, there was no inhibitory effect of pathogen adhesion by bacteriocin treated with protease and inhibition activity of pathogen adhesion was partially decreased by heat-treated bacteriocin. According to biochemical and phylogenetic analysis, MLK27 strain was identified as Lactobacillus brevis MLK27. In conclusion, our results have shown that L. brevis MLK27 has ability to establish in human gastrointestinal tract and to prevent pathogenic L. monocytogenes infections, which is able to be considered as probiotic strains. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
