| Abstract | A cost-effective fertilizer-based optimum culture medium was formulated for the mass production of Spirulina platensis using NPK-10:26:26 complex fertilizer and growth results were compared with several standard culture media. The microalga was grown in an illuminated white LED with 50 μmol photons m$^{−2}$ s$^{−1}$ and 30 °C temperature under orbital shaking. The optimum NPK fertilizer medium was formulated by varying NPK-10:26:26 fertilizer and sodium bicarbonate loading for which maximum biomass growth rate was obtained. The newly formulated fertilizer medium contains NPK-10:26:26 (0.76 g l$^{−1}$), sodium bicarbonate (10.0 g l$^{−1}$), sodium chloride (1.0 g l$^{−1}$), and micro nutrients (1.0 ml l$^{−1}$). Maximum growth rate was recorded between 14 and 15 days and corresponding biomass concentration, chlorophyll, protein, and lipid were found to be 1.22, 8.92 g l$^{−1}$, 52.35, and 14.84 %, respectively. Above growth results using NPK fertilizer were superior over standard culture media, and 50.0 % cost saving was achieved using newly formulated NPK-10:26:26 fertilizer medium for Spirulina growth in comparison to the standard culture media. Uptake of nutrients (i.e., carbon, nitrogen, phosphorous, and potassium) and physicochemical parameters (i.e., pH and conductivity) were measured to monitor Spirulina growth. |

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.
