| Abstract | Resting cell suspensions of Neisseria meningitidis group B (strain 2091) do not catabolize citrate as the sole substrate to an appreciable degree. When another substrate, such as glutamate, is also present to furnish energy for transport, citrate metabolism is greatly stimulated. Within limits, the amount of CO2 produced from citrate is proportional to the amount of glutamate added. When the cells are disrupted, citrate is degraded at a rapid rate and the stimulatory effect of glutamate is completely eliminated. Pronounced stimulation of citrate metabolism by glutamate was demonstrated in 12 of 13 strains of N. meningitidis tested and only 1 of 6 strains of N. lactamicus. The remaining strains of N. lactamicus and one each of N. gonorrhoeae, N. flavescens, and N. flava did not utilize significant amounts of citrate in the absence or presence of glutamate. N. catarrhalis shared with Mima polymorpha and Moraxella glucidolytica a capability to catabolize citrate at a rapid rate without added glutamate. It is concluded that tests of glutamate-stimulated citrate metabolism may contribute to species characterization in the genus Neisseria. |

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.
