| Abstract | The physicochemical properties of hemp biomass structure to pretreatment and enzymatic hydrolysis were investigated to improve upon reducing sugar production for biofuel development. Sodium hydroxide pretreated biomass (SHPB) yielded maximum conversion of holocellulose into reducing sugar (72 %). Scanning electron microscopy (SEM) revealed that enzymatic hydrolysis generated regular micropores in the fragmented biomass structure. The thermogravimetric analysis (TGA) curve suggested the degradation of hemicellulose and cellulose, which conformed well to the subsequent nuclear magnetic resonance (NMR) studies indicating the presence of α- and β-glucose (28.4 %) and α- and β-xylose (10.7 %), the major carbohydrate components commonly found in hydrolysis products of hemicellulose and cellulose. Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectra showed stretching modes of the lignin acetyl group, suggesting the loosening of the polymer matrix and thus the exposure of the cellulose polymorphs. X-ray diffraction pattern indicated that enzymatic hydrolysis caused a higher crystallinity index (36.71), due to the fragmentation of amorphous cellulose leading to the reducing sugar production suitable for biofuel development. |

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.
