| Abstract | The discrimination of distinct cultures among morphologically similar Streptomyces soil isolates (dereplication) and the detection of specific biosynthetic pathways in these strains are important steps in the selection of microorganisms to include in a natural products library. We have developed methods for analysis of actinomycetes using the RiboPrinter microbial characterization system, an automated instrument that performs ribotyping on bacterial samples. To evaluate our dereplication method, 26 Streptomyces isolates, obtained from soil samples collected in Maui, Hawaii, were ribotyped and compared with each other, using the RiboPrinter. The strains were also compared by 16S rDNA sequence analysis, MIDI fatty acid analysis, and LC-MS profiling of fermentation extracts. The RiboPrinter was able to identify closely related isolates and to discriminate between morphologically similar isolates with unique genetic, fatty acid and fermentation profiles. For the detection of biosynthetic genes, a 1,006-bp probe containing a portion of an adenylation domain of a non-ribosomal peptide synthetase (NRPS) was employed. Using this alternate probe in place of the standard ribosomal probe, the RiboPrinter was able to detect NRPS genes in several strains of Streptomyces. These results demonstrate that the RiboPrinter has multiple applications in a natural products research program. |

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.
