| Abstract | The outer membrane of Escherichia coli was altered as a consequence of lysogeny by bacteriophages P1 and P1 cmts. The predominant change was a reduction in the size of lipopolysaccharide to a heptose-deficient form. P1 cmts lysogens were still sensitive to several bacteriophages but were resistant to lambda vir. Neither whole cells nor solubilized outer membranes from P1 cmts lysogens were able to inactivate lambda vir, and 32P-labeled lambda vir was unable to adsorb to P1 cmts lysogens. P1 cmts lysogens were also affected in maltose transport. The level of periplasmic maltose-binding protein was reduced somewhat, but there was no significant reduction in the level of the outer membrane lambda receptor (LamB). These membrane abnormalities were all corrected in strains cured of P1 cmts. It is suggested that P1 cmts affects lipopolysaccharide biosynthesis by a phage conversion mechanism and consequently the function of the lambda receptor. |

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.
