Abstract:
This thesis reports the effect of the non-toxic cyanobacterium Oscillatoria agardhii CYA29 and its spent medium on the cell-bound toxin levels in Microcystis aeruginosa PCC7820 and Nodularia sp. PCC7804. Microcystin levels were elevated when O. agardhii or its spent medium were added to cultures of M. aeruginosa PCC7820. This effect was also observed for two nodularin variants in Nodularia PCC7804. However, growth of M. aeruginosa in its own spent medium did not lead to elevated microcystin levels.

Abstract:
Cyanobacteria are a diverse and widely distributed group of organisms common in soil and in both marine and freshwater. Under favorable conditions they can reproduce explosively, forming dense concentrations called blooms. Fresh water cyanobacterial blooms in particular are commonly associated with toxin production in drinking water supplies and are increasingly becoming a risk to human health. Beyond toxin production these extremely complex, constantly interacting and changing microbial communities have vast impacts on their surrounding ecosystem.

The native organisation of the photosynthetic complexes in cyanobacterial thylakoid membranes is still relatively unclear.
