γ-Lindane Increases Microcystin Synthesis in Microcystis aeruginosa PCC7806

Marine Drugs, 2015
HCH factories, and the waste dumpsites associated to its production, have become a global environmental concern, and their runoff could pollute ground and surface waters with high levels of the pollutant.

Microcystins with Modified Adda⁵-Residues from a Heterologous Microcystin Expression System

ACS Omega
Microcystins are hepatotoxic cyclic heptapeptides produced by some cyanobacterial species and usually contain the unusual β-amino acid 3S-amino-9S-methoxy-2S,6,8S-trimethyl-10-phenyl-4E,6E-decadienoic acid (Adda) at position-5. The full microcystin gene cluster from Microcystis aeruginosa PCC 7806 has been expressed in Escherichia coli.

Growth and antioxidant system of the cyanobacterium Synechococcus elongatus in response to microcystin-RR [PDF]

, 2005
Microcystins, one type of the cyanobacterial toxins, show a broad range of hazardous effects on other organisms. Most of the researches on the toxic effects of microcystins have involved in animals and higher plants.

The use of a benign fast-growing cyanobacterial species to control microcystin synthesis from Microcystis aeruginosa

Frontiers in Microbiology
IntroductionMicrocystis aeruginosa (M. aeruginosa), one of the most abundant blue-green algae in aquatic environments, produces microcystin by causing harmful algal blooms (HABs).

Evaluation of a point-of-use device used for autoantibody analysis and its potential for following microcystin leucine-arginine exposure

Frontiers in Sensors
Introduction: Globally, the need for measuring exposure to algal toxins has become urgent due to ever-increasing reports of contamination in sea and freshwater, in shellfish and fish stocks and in aerosols.Methods: To address this issue, we evaluated the

Microcystin enhances the fitness of microcystin producing cyanobacteria at high light intensities by either preventing or retarding photoinhibition [PDF]

, 2013
Several genera of cyanobacteria produce microcystin, a monocyclic peptide, with a unique chemical structure. To date, there have been over a 100 different structural variants of microcystin which have been identified.

Variability of the microcystin synthetase gene cluster [PDF]

, 2005
In populations of Planktothrix, microcystin-producers and non-producers, which are morphologically identical, coexist. In order to develop a basis for the reliable detection of microcystin producers in field samples with polymerase chain reaction (PCR ...

Degradation of microcystin-LR by aquatic bacteria. [PDF]

, 2007
Microcystins are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions.
