Journal ArticleDOI
Identification of 12 hepatotoxins from a homer lake bloom of the cyanobacteria microcystis aeruginosa microcystis viridis and microcystis wesenbergii nine new microcystins
Michio Namikoshi,Kenneth L. Rinehart,Ryuichi Sakai,Richard R. Stotts,Andrew M. Dahlem,Val R. Beasley,Wayne W. Carmichael,William R. Evans +7 more
Journal ArticleDOI
Analysis and purification of toxic peptides from cyanobacteria by reversed-phase high-performance liquid chromatography
Ken-ichi Harada,Kenji Matsuura,Makoto Suzuki,Hisao Oka,Mariyo F. Watanabe,Shinshi Oishi,Andrew M. Dahlem,Val R. Beasley,Wayne W. Carmichael +8 more
TL;DR: A total system for the analysis and isolation of microcystins was established and the adsorptive powers of three commercially available C18 cartridges successfully applied to the clean up of three of the toxins.
Journal ArticleDOI
Improved method for purification of toxic peptides produced by cyanobacteria.
Ken-ichi Harada,Makoto Suzuki,Andrew M. Dahlem,Val R. Beasley,Wayne W. Carmichael,Kenneth L. Rinehart +5 more
TL;DR: The improved method involves ODS-silica gel extraction, and separation on silica gel and HPLC with UV (238 nm) detector, and enables a rapid isolation of peptide toxins from cyanobacteria.
Journal ArticleDOI
Isolation and characterization of the minor components associated with microcystins LR and RR in the cyanobacterium (blue-green algae).
Ken-ichi Harada,Kenji Matsuura,Makoto Suzuki,Mariyo F. Watanabe,Shinshi Oishi,Andrew M. Dahlem,Val R. Beasley,Wayne W. Carmichael +7 more
TL;DR: Ultraviolet and 1H-NMR spectral data for both components demonstrate clear structural difference of these cyclic peptides from the parent toxins, which is probably responsible for the marked decreases in their observed toxicities.
Journal ArticleDOI
Excretion of deoxynivalenol and its metabolite in milk, urine, and feces of lactating dairy cows.
TL;DR: Feeding deoxynivalenol-contaminated diets for 5 d did not alter feed intake or milk production nor were the milk concentrations of calcium, phosphorus, sodium, potassium, magnesium, or nitrogen altered.
