Two microcystins, MC-LR and [D-Leu1]MC-LR, present in La Plata Basin blooms, are differentiated by substitution of D-Alanine for D-Leucine at position 1. Our objective was to evaluate acute toxicity of [D-Leu1]MC-LR and MC-LR in mice (N:NIH Swiss) an

The aim of this study was to evaluate the effects of short-term (hours) exposure to solar UV radiation (UVR, 280-400 nm) on the physiology of Microcystis aeruginosa. Three solar radiation treatments were implemented: (i) PAR (PAR, 400-700 nm), (ii) T

Publikováno v: Rapid communications in mass spectrometry : RCM. 29(2)

High-resolution mass spectrometry was applied to the study of a Microcystis aeruginosa strain previously reported as a [D-Leu(1)]MC-LR producer. Detailed analysis revealed new microcystin (MC) variants produced from the strain, and seven of these wer
