| Abstract | Toennies, G. (Temple University School of Medicine, Philadelphia, Pa.), D. N. Das, and F. Feng. Pantothenate and coenzyme A in bacterial growth. J. Bacteriol. 92:707–713. 1966.—The effect of environmental pantothenate levels on the growth of Streptococcus faecalis 9790 was studied in terms of growth rate, depletion phenomena, cellular coenzyme A (CoA) content, and differential rates of wall and membrane synthesis. Low concentrations of pantothenate yielded normal exponential growth curves up to peak turbidities which are a function of pantothenate concentration. Attainment of these peaks was followed by lysis. Under such conditions, bacterial CoA increased initially in proportion with cell substance, but attained a peak level much earlier than cell substance, and then gradually decreased down to vanishing amounts. With higher pantothenate concentrations, cellular CoA levels increased to a maximum, and, under these conditions, the CoA content remained constant during exponential growth. Four-fifths of the pantothenate requirement of growing cells was eliminated by environmental oleate and palmitate. When CoA disappeared during growth on low pantothenate levels, cell wall synthesis seemed to continue at nearly normal rates, but membrane synthesis was severely curtailed. The data suggest that in fermentative organisms pantothenate action might be confined to wall and membrane synthesis, that these two processes differ in their quantitative dependence on pantothenate, and that pantothenate might occur in the form of acyl carrier protein as well as CoA. |

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.
