| Abstract | Menaquinone 7 (MK-7) is nutritionally important metabolite found by fermentation mainly using B. subtilis species. In this study, soybean medium was modified to improve the MK-7 production using Bacillus subtilis NCIM 2708 under solid state fermentation. The objective of this study was to produce large amount of MK-7 within a short period of time. Nine nutritional components viz. glycerol, mannitol, dextrose, sucrose, yeast extract, malt extract, K$_{2}$HPO$_{4}$, MgSO$_{4}$.7H$_{2}$O and CaCl$_{2}$ were investigated to obtain the maximum MK-7 concentration. The highest MK-7 concentration 39.039 μg/g was obtained after 24 h of fermentation in the following optimised medium components: soybean 20 g, glycerol 40 ml/kg, mannitol 60 g/kg, yeast extract 4 g/kg, malt extract 8 g/kg and calcium chloride 4 g/kg. The maximum production of MK-7 56.757 μg/g was predicted by point prediction tool of Design Expert 7.1 software (Statease Inc. USA). This data shows 68.78 % validity of the predicted model. |

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.
