| Abstract | Little is known about the genus Verrucosispora though it does contain organisms which produce novel antibiotics. A set of genus-specific oligonucleotide primers was generated to gain an insight into the presence, distribution and taxonomic diversity of members of this genus in diverse samples taken from marine habitats. In silico and pure culture studies showed that the primers matched perfectly with target sequences of the 16S rRNA genes of representatives of the genus Verrucosispora. The primers, designated S-G-Verr-0195-a-S-20 and S-G-Verr-1152-a-A-18, amplified an ≈960 bp stretch of the 16S rRNA genes of Verrucosispora strains but not those of representatives of other genera classified in the family Micromonosporaceae. Genus-specific amplicons were detected from 17 out of 20 community DNA samples prepared from diverse marine sediments and coastal soils. Phylogenetic analysis of over 40% of clones derived from five of the samples indicated they belonged to novel Verrucosispora species. The primers were also used to confirm the identity of Verrucosispora-like strains isolated from two of the environmental samples. The primers can be used to facilitate the isolation of novel Verrucosispora strains by allowing prescreening of environmental samples and the subsequent identification of verrucosisporae on selective isolation plates. For this purpose, a novel medium facilitating the recovery of Verrucosispora strains was formulated and used to recover novel isolates validated using the novel PCR primers. This medium may be useful as the basis for development of a selective medium. |

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.
