This thesis aims at furthering the knowledge regarding the neurotoxin β-N-methylamino-L-alanine (BMAA) produced by cyanobacteria (’blugreen algae’) and its potential association to neurodegenerative diseases. BMAA was found in bloom forming cyanobacteria of the Baltic Sea as well as in fish and zooplankton (bioaccumulation). Experimental studies showed that BMAA can inhibit growth and nitrogen fixation in cyanobacteria, although its function remains unclear. BMAA was detected in human cerebrospinal fluid of a few control individuals as well as in one ALS-patient.
