| Abstract | In the present study, we assessed the bacterial richness and composition of sediment samples collected in and around the port of Aveiro, on the Atlantic coast of mainland Portugal. Sediment samples were collected in five locations: two within the port harbor, two in port areas along a channel adjacent to the harbor and one in a relatively undisturbed reference location. These areas were characterized as under high, medium and no port activity, respectively. In-depth, barcoded-pyrosequencing analysis indicated that port activity affects the composition and abundance of bacterial communities colonizing surface sediments. Sampling sites under the influence of port activities (channel and harbor) were associated with higher relative abundances of Desulfobacterales and a marked decline in the abundance of Flavobacteriia. In addition, there was a pronounced prevalence of operational taxonomic units (OTUs) in the port area that were closely related to hydrocarbon-degrading bacteria (Desulfococcus spp.), antifouling paint (bacterium strain WH6-7) and copper rich sediments (bacterium strain CanalPD16A). Here we provide evidence that specific phylotypes detected have the potential to be used as biomarkers and should be evaluated in future studies as proxies for sediment disturbance associated with port activity. |

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.
