| Abstract | Survival of microorganisms in the Antarctic and Arctic conditions of life requires of the relevant genera and species special adaptability and resistance against stressors such as lack of substrate, UV-radiation, low temperatures for a long time and short-term intense heat during the Antarctic and Arctic summer. Therefore genetic adaptation of Antarctic and Arctic organisms to stress factors would be expected. All this suggests in a global aspect synthesis of new metabolites with unique structures and specific biological activity. Antarctic and Arctic polar regions are considered as a huge reservoir of microorganisms with versatile antimicrobial potential. Our studies are motivated by an interest in the functional role played by natural products in the ecological interactions of the polar strains with the other members of the microbial community. This overview presents some of the most important secondary metabolites (antibiotics, alkaloids, high carbon amino acids, nitro compounds, diketopiperazines etc.) produced by Antarctic and Arctic microorganisms. The secondary metabolites biosynthesis probably plays an important role in the adaptation and survival of microorganisms in the ice deserts of Antarctica and the Arctic. |

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.
