General description

Microcystin-LY is generally produced by cyanobacteria in freshwater systems and is found as a toxic analog of microcystin.

Application

Microcystin-LY may be used as an analytical reference standard for the determination of the analyte in raw and treated waters using high-performance liquid chromatography with photo-diode array detection (HPLC-PDA).

Microcystins (MC) are a group of over 60 cyclic heptapeptide hepatotoxins produced by cyanobacteria. The 1-octanol/water partition coefficients (log P) of MC-LR, -LY, -LW and -LF have been estimated by HPLC to be 2.16, 2.92, 3.46 and 3.56, respectively. Their

A bacterium termed 7CY, capable of decomposing cyanobacterial toxins, was isolated from surface water sample of Lake Suwa and degradation of microcystin-RR and nodularin-Har was investigated. The isolated 7CY was a gram-negative, aerobic bacillus, and a member of a genus

The cyanobacterial toxins microcystins (MC) are known to affect many processes in plants. Their presence in the water used for irrigation may have considerable impact on the survivorship, growth and development of plants. In this study, a crude extract of

The three-dimensional structure of the two hepatotoxic microcystins LR and LY has been determined by two-dimensional nuclear magnetic resonance (2D NMR) spectroscopy and distance geometry calculations. For the microcystin LY a single family of highly convergent structures was obtained. This
