| Abstract | Potato chip processing waste of trimmed potato, potato peel and substandard (low-quality) potato chips, obtained from a potato chip processing plant, were used as substrates for chitosan production from Rhizopus oryzae. It was cultured on each waste product at 30 ± 2°C and 70% moisture content for 21 days. Fermented potato peel had the highest yield after 5 days of fermentation. The cultivation condition of chitosan obtained from R. oryzae was optimum for a peel size of less than 6 mesh, 70% moisture content and a pH of 5. Furthermore, the best extraction condition was using 46% sodium hydroxide at 46°C for 13 h followed by 2% acetic acid at 95°C for 8 h. The maximum chitosan yield obtained by these conditions was 10.8 g/kg substrate. Fungal chitosan properties were found to be 86–90% degree of deacetylation, molecular weight of 80–128 kDa and viscosity of 3.1–6.1 mPa s. Therefore, potato peel could be applied as a low cost substrate for chitosan production from R. oryzae. |

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.
