| Abstract | Different methods of pretreatment including alkali treatment, treatment with ultrasound, biological treatment using laccase enzyme and combined treatment like ultrasound-laccase for Napier grass have been tried. With alkali pretreatment optimized conditions obtained were sodium hydroxide 0.3% w/v giving 86% delignification at temperature of 80°C, treatment time of 2h. In physical methods of treatment ultrasound, at a temperature of 45°C, treatment time of 2h, operating at frequency 24kHz and power of 100W gave 18% delignification. For laccase pretreatment, optimized conditions obtained were 300rpm impeller speed, enzyme concentration 10U/gm of Napier grass gave 50% delignification with cellulose. The optimized conditions for delignification by using combination treatment of ultrasound & enzymatic were obtained at 24kHz frequency, 100W giving 75% of delignification in 6h. An enhancement in lignin degradation by 25% and reduction in the treatment time from 12 to 6h is achieved as compared to only laccase treatment. |

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.
