| Abstract | The cDNAs of six manganese-dependent peroxidases (MnPs) were isolated from white-rot fungus Polyporus brumalis. The MnP proteins shared similar properties with each other in terms of size (approximately 360–365 amino acids) and primary structure, showing 62–96 % amino acid sequence identity. RT-PCR analysis indicated that these six genes were predominantly expressed in shallow stationary culture (SSC) in a liquid medium. Gene expression was induced by treatment with dibutyl phthalate (DBP) and wood chips. Expression of pbmnp4 was strongly induced by both treatments, whereas that of pbmnp5 was induced only by DBP, while pbmnp6 was induced by wood chips only. Then, we overexpressed pbmnp4 in P. brumalis under the control of the GPD promoter. Overexpression of pbmnp4 effectively increased MnP activity; the transformant that had the highest MnP activity also demonstrated the most effective decolorization of Remazol Brilliant Blue R dye. Identification of MnP cDNAs can contribute to the efficient production of lignin-degradation enzymes and may lead to utilization of basidiomycetous fungi for degradation of lignin and numerous recalcitrant xenobiotics. |

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.
