| Abstract | This work aims to enhance the glucosamine production by Aspergillus sp. BCRC 31742 via the optimization of dissolved oxygen (DO) control strategy. Influence of DO levels (20, 30, 40, 50 and 60%) on the glucosamine production was investigated, and it was found that the highest specific glucosamine production rate during 0-12h and 12-60 h was obtained at DO level of 30% and 50%, respectively. Accordingly, a two-stage DO control strategy was proposed, namely, DO was controlled at 30% during 0-12h and 50% during 12-60 h. With this DO shifting strategy, the highest glucosamine production reached 14.37 g/L, which was 1.30 times that without DO control. Here, the developed two-stage DO control strategy may be useful for the industrial production of glucosamine, and also may be meaningful for the production of other fine chemicals by the filamentous fungi fermentation. |

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.
