| Abstract | In the biocontrol of harmful algal blooms, there has been considerable interest about the role of algicidal bacteria in algicidal activity. In this experiment, two novel algicidal bacteria (strains NP23 and AM11) against Chlorella pyrenoidosa were isolated from the Baiguishan reservoir in China. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strains NP23 and AM11 belonged to Enterobacter cloacae and Gibberella moniliformis, respectively. To further understand the algicidal activities, five parameters including the chlorophyll a content, cell survival rate, superoxide dismutase (SOD) peroxide dismutase (POD), and catalase (CAT) were tested in the C. pyrenoidosa cells after inoculation with the algicidal bacteria Enterobacter cloacae NP23 and Gibberella moniliformis AM11. As a result, the growth of the treated C. pyrenoidosa was significantly restrained with a great decline of chlorophyll a content. Meanwhile, three antioxidase activities of the treated C. pyrenoidosa were initially stimulated from day 1 to day 3 but then dramatically inhibited at low level. These results induced that the oxidative imbalance (i.e., inhibition of antioxidase activities) caused by algicidal bacteria could be the killing agent of the C. pyrenoidosa cells. |

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.
