Abstract | Batch Experiments with the combination use of inhibitors were conducted to identify the mechanism of N2O emission from anoxic-aerobic sequencing batch reactors (SBR) acclimated under different oxygenation levels. Oxygenation has an important effect on the N2O emission and most of the N2O was produced during the aerobic phase, in spite of the oxygenation level. During the anoxic phase, nitrate ammonification was the major producer of N2O while denitrification performed as a sink of N2O. During the aerobic phase, both nitrifier denitrification and coupled nitrification-denitrification were responsible for N2O emission in SBR with low and high oxygenation, while nitrifier denitrification was the major source of N2O emission in SBR with mid oxygenation. |

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.
