An investigation into factors influencing the production and degradation of microcystins. (2007)
Thesis
GRAHAM, D.J.L. 2007. An investigation into factors influencing the production and degradation of microcystins. Robert Gordon University, PhD thesis.

Microcystins (MCYST) potently inhibit protein phosphatases and these cyclic heptapeptides are powerful hepatotoxins. They are known to be secondary metabolites produced by several species of cyanobacteria. The release of these peptides into water sup...

Thesis
BELLU, E. 2007. Detection, analysis, and photocatalytic destruction of the freshwater taint compound geosmin. Robert Gordon University, PhD thesis.

A significant issue affecting the aquaculture and water industries is the presence of off-flavour compounds in water, which cause problems by imparting an undesirable earthy/musty flavour and smell to water and fish. Two predominant off-flavour compo... Read More about Detection, analysis, and photocatalytic destruction of the freshwater taint compound geosmin..

In fresh waters where cyanobacteria (blue-green algae) flourish, dense growths known as blooms occur. Such blooms present a threat to human and animal health as many of these cyanobacteria produce toxins. One such group of toxins are the microcystins...
