Journal ArticleDOI
First report of the cyanotoxins cylindrospermopsin and deoxycylindrospermopsin from raphidiopsis curvata (cyanobacteria)
Renhui Li,Wayne W. Carmichael,Scott M. Brittain,Geoffrey K. Eaglesham,Glen R. Shaw,Yongding Liu,Makoto M. Watanabe +6 more
TL;DR: A mouse bioassay did not show lethal toxicity when tested at doses up to 1500 mg dry weight cells·kg−1 body weight within 96 h, demonstrating that production of primarily deoxy‐CYN does not lead to significant mouse toxicity by strain HB1, and suggests that Raphidiopsis belongs to the Nostocaceae, but this requires confirmation by molecular systematic studies.
Journal ArticleDOI
Taxonomic revision of water-bloom-forming species of oscillatorioid cyanobacteria.
Shoichiro Suda,Makoto M. Watanabe,Shigeto Otsuka,Aparat Mahakahant,Wichien Yongmanitchai,Napavarn Nopartnaraporn,Yongding Liu,John G. Day +7 more
TL;DR: A polyphasic approach was used to clarify the taxonomy of the water-bloom-forming oscillatorioid cyanobacteria and proposed either emended or new taxonomic descriptions for Planktothrix agardhii, PlankTothrix rubescens, and Limnothrix redekei.
Journal ArticleDOI
Phylogenetic relationships between toxic and non‐toxic strains of the genus Microcystis based on 16S to 23S internal transcribed spacer sequence
Shigeto Otsuka,Shoichiro Suda,Renhui Li,Masayuki Watanabe,Hiroshi Oyaizu,Satoshi Matsumoto,Makoto M. Watanabe +6 more
TL;DR: Derived maximum likelihood and DNA distance trees indicated that Microcystis can be divided into three clusters, andPhylogenetic analysis based on intergenic spacer sequences was thought to be effective for understanding relationships among closely related species and strains.
Journal ArticleDOI
A proposal for the unification of five species of the cyanobacterial genus Microcystis Kützing ex Lemmermann 1907 under the rules of the Bacteriological Code.
Shigeto Otsuka,Shoichiro Suda,T. Satoshi Shibata,Hiroshi Oyaizu,Satoshi Matsumoto,Makoto M. Watanabe +5 more
TL;DR: Genomic DNA homologies were examined from six Microcystis (cyanobacteria) strains, including five different species, and it is proposed to unify these five species into M. aeruginosa.
Journal ArticleDOI
Isolation and identification of the cyanotoxin cylindrospermopsin and deoxy-cylindrospermopsin from a Thailand strain of Cylindrospermopsis raciborskii (Cyanobacteria).
Renhui Li,Wayne W. Carmichael,Scott M. Brittain,Geoff Eaglesham,Glendon Reginald Shaw,A. Mahakhant,N. Noparatnaraporn,W. Yongmanitchai,Kunimitsu Kaya,Makoto M. Watanabe +9 more
TL;DR: This is the first report from Asia of a CYN, deoxy-CYN producing Cylindrospermopsis raciborskii, and it is feared that this strain may contain CYN/CYN hybrids.
