However the surveys were performed only in limited area of each country. In order to obtain more detailed information, screening of N. navis-varingica was primarily performed in the Philippines. During the survey, we confirmed that all strains of N. navis-varingica isolated from Bulacan, Manila Bay did not produce DA, but did produce isodomoic acids A (IA) and B (IB). The confirmation of IA and IB was done by the analyses of UV-spectra, LC-MS/MS, proton NMR and ^<13>C NMR. Re-observation of the toxin composition including IA and IB simultaneously with DA was performed on the former chromatograms. All the strains positive for DA and/or its derivatives isolated from estuary areas of Bacoor, Tanauan and San Roque, were confirmed to produced DA and IB, indicating that there is a local difference in toxin composition in the Philippines. All of the toxic strains were identified as N. navis-varingica. This is the first report of pennate diatom that produces IA and IB instead of DA as major toxin component. This finding might be a useful step in pursuing the DA production mechanism. Additionally fourty one Pseudo-nitzschia strains isolated from offshore areas of above mentioned estuaries were tested for DA, but all of them did not show any sign of DA production.","subitem_description_type":"Abstract"}]},"item_4_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15083/00040761","subitem_identifier_reg_type":"JaLC"}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"International
