| Abstract | The new bacteriocin is produced from Bacillus lentus NG121 isolated from Khameera – a traditional fermented food from Himachal Pradesh, India which has been reported for the first time in the literature to produce bacteriocin and exhibited very high activity units of 20 × 105 AU (Arbitrary Units)/ml. This bacteriocin was partially purified and was further characterized to assess its preservation characteristics. It showed strong antimicrobial activity against the most challenging and serious test indicators like Listeria monocytogens and Staphylococcus aureus. There was a drastic decrease up to 70% in viable cells of the indicators within the first 10 h of adding partially purified bacteriocin thus proving its bactericidal action. It could withstand the high heat of 100 °C for 10 min of heating time without losing any activity. A wide range of pH tolerance i.e. from 5.0–10.0 was expressed by this bacteriocin. It was found completely sensitive to proteolytic enzyme trypsin. The unique combination of all the above mentioned characteristics makes the bacteriocin of newly isolated Bacillus lentus NG121, a food grade bacteria, highly desirable for preservation of different food items in the food industry. |

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.
