Journal ArticleDOI
A Non-Toxigenic But Morphologically And Phylogenetically Distinct New Species Of Pseudo-Nitzschia, P. Sabit Sp. Nov. Bacillariophyceae)
Sing Tung Teng,Po Teen Lim,Hong Chang Lim,María Rivera-Vilarelle,Sonia Quijano-Scheggia,Yoshinobu Takata,Michael A. Quilliam,Matthias Wolf,Stephen S. Bates,Chui Pin Leaw +9 more
TL;DR: A new species of Pseudo‐nitzschia (Bacillariophyceae) is described from plankton samples collected from Port Dickson and Manzanillo Bay, Malaysia, with a distinctive falcate cell valve, from which they form sickle‐like colonies in both environmental samples and cultured strains.
Journal ArticleDOI
Production of isodomoic acids A and B as major toxin components of a pennate diatom Nitzschia navis-varingica
Yuichi Kotaki,Elsa F. Furio,Masayuki Satake,Nina Lundholm,Tsutaki Katayama,Kazuhiko Koike,Virgilio P. Fulgueras,Fe Farida A. Bajarias,Yoshinobu Takata,Kenji Kobayashi,Shigeru Sato,Yasuwo Fukuyo,Masaaki Kodama +12 more
TL;DR: This is the first report of a diatom that produces isodomoic acids A and B as major toxin components in Asian waters, and it is believed that domoic acid derivatives from Nitzschia navis-varingica have been determined.
Journal ArticleDOI
Toxic Alexandrium minutum (Dinophyceae) from Vietnam with new gonyautoxin analogue
Po Teen Lim,Po Teen Lim,Shigeru Sato,Chu Van Thuoc,Nguyen Thi Minh Huyen,Yoshinobu Takata,Makoto Yoshida,Atsushi Kobiyama,Kazuhiko Koike,Takehiko Ogata +9 more
TL;DR: Clonal cultures of Alexandrium species collected from a shrimp pond on the northern coast of Vietnam were established and morphologically identified as Alexandrium minutum, and a new gonyautoxin derivative was detected by HPLC, representing the first report of this toxin analogue.
Journal ArticleDOI
Physiological and transcriptional responses to inorganic nutrition in a tropical Pacific strain of Alexandrium minutum: Implications for the saxitoxin genes and toxin production.
TL;DR: Investigating the physiological responses of a tropical Pacific strain of Alexandrium minutum growing with nitrate or ammonium, and with various nitrogen to phosphorus supply ratios revealed that the cellular toxin quota (Qt) was higher in P-depleted, nitrate-grown cultures.
Journal ArticleDOI
Direct contact between Pseudo-nitzschia multiseries and bacteria is necessary for the diatom to produce a high level of domoic acid
TL;DR: Results show that direct contact between living bacteria and P. multiseries is necessary for producing high levels of domoic acid in P.–nitzschia Multiseries.
