| Abstract | Banana production has been severely hindered by the long-term practice of monoculture agriculture. Fusarium wilt, caused by the Fusarium oxysporum f. sp. cubense (FOC), is one of the most destructive diseases that can afflict banana plants. It is both necessary and urgent to find an efficient method for protecting banana production worldwide. In this study, 57 antagonistic bacterial strains were isolated from the rhizospheres of healthy banana plants grown in a heavily wilt-diseased field; of the 57 strains, six strains with the best survival abilities were chosen for further study. Compared with the control and the other strains in the greenhouse experiment, W19 strain was found to observably decrease the incidence of Fusarium wilt and promote the growth of banana plants when combined with the organic fertilizer (OF). This strain was identified as Bacillus amyloliquefaciens based on its morphological, physiological, and biochemical properties, as well as 16S rRNA analysis. Two kinds of antifungal lipopeptides (iturin and bacillomycin D) produced by W19 strain were detected and identified using HPLC–ESI-MS. Another lipopeptide, called surfactin, was also produced by the thick biological film forming W19 strain. In addition to lipopeptides, 18 volatile antifungal compounds with significant antagonistic effect against F. oxysporum were detected and identified using gas chromatography–mass spectrometer (GC–MS). The work described herein not only highlights how the bioorganic fertilizer with B. amyloliquefaciens can be used to control Fusarium wilt of banana but also examines some of the potential mechanisms involved in the biocontrol of Fusarium wilt. |

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.
