Methods for rapid extraction of microcystin-LR and microcystin-RR

浙江大学学报. 农业与生命科学版, 2005
Simple analysis methods using microwave and boiling waterbath to solve the problem for microcystin-LR (MCLR) and microcystin-RR (MCRR) extraction from cyanobacteria cells were studied as a substitute for the traditional solvent extraction methods. Standards were used to confirm the feasibility and efficiency of both methods.

Effects of microcystins on and toxin degradation by Poterioochromonas sp.

, 2005
A Chrysophyceae species, Poterioochromonas sp., was isolated from Microcystis cultures. This species can efficiently prey on Microcystis and can grow faster phagotrophically than autotrophically. The growth of Poterioochromonas sp.

Seven microcystins from Microcystis waterbloom in Lake Dalai, China

, 1997
Seven types of microcystins, isolated from Microcystis waterbloom in Lake Dalai, were characterized. The major toxins: MCYST-LR, MCYST-RR, (D-Asp-3) MCYST-LR and (Dha-7) MCYST-LR were identified by high performance liquid chromatography (HPLC), as ...

The short-term effect of nitrogen on freshwater cyanobacteria and cyanotoxins

Frontiers in Water
Toxic cyanobacterial blooms are a worldwide concern. Nutrients are among the numerous factors that trigger cyanobacterial blooms and the production of cyanotoxins. This study aimed to assess the effect of nitrogen on cyanobacteria and cyanotoxins through

Investigation on intake, accumulation and toxicity of microcystins to silver carp

, 2005
Daily intake and accumulation of microcystins (MCYSTs, MCs) in silver carp (Hypophthalmichthys molitrix) were investigated under lab conditions by feeding the fish exclusively with fresh toxic Microcystis bloom at a density of 6 x 10(9) algal cells L-1 ...
