| Abstract | Les mangroves constituent un écosystème particulier. Leur développement est fortement lié à leur fonctionnement. La microflore y joue un rôle de premier plan. Grâce à son activité de dégradation de la matière organique, elle pourvoie, aux organismes supérieurs, les éléments nutritifs d’importance tels que l’azote et le phosphore indispensables à leurs cycles biologiques. Il existe une relation entre la composition globale des microorganismes et la demande en éléments nutritifs. Une simulation artificielle de la dégradation des hydrocarbures par les bactéries demande une addition d’azote et de phosphore. La biodégradation qui est un phénomène naturel de dégradation des molécules organiques par les microorganismes (bactéries et champignons, etc.), dont la croissance s’effectue par l’oxydation du carbone utilisé comme source d’énergie est une réaction qui met en jeu l’azote et le phosphore qui participent à la synthèse protéique. Lorsque l’oxydant est représenté par l’oxygène, on parle de condition d’aérobiose. Dans le cas d’anaérobiose, l’oxygène est remplacé par les nitrates, phosphates, sulfates ou le méthane.Mots clés : mangroves, microflore, pollution, biodégradation, réhabilitation. |

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.
