1. On the ecophysiology of Baltic cyanobacteria focusing on bottom-up factors
Sammanfattning : Cyanobacterial blooms in the Baltic Sea are dominated by diazotrophic cyanobacteria, i.e. Aphanizomenon sp. and Nodularia spumigena. LÄS MER
2. Ecological implications of the production of toxic substances by fish killing phytoplankton species grown under variable N:P-ratios
Sammanfattning : The influence of different nutrient conditions on the production of toxins was studied in certain fishkilling haptophytes (e.g. Prymnesium parvum and Chrysochromulina polylepis). LÄS MER
3. Managing Eutrophic Waters in Artificial Recharge Plants : Cyanotoxin risk in Swedish freshwaters
Sammanfattning : In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues.

4. Distribution and Long-term Effects of the Environmental Neurotoxin β-N-methylamino-L-alanine (BMAA) : Brain changes and behavioral impairments following developmental exposure
Sammanfattning : Many cyanobacteria are reported to produce the nonprotein amino acid β-N-methylamino-L-alanine (BMAA). Cyanobacteria are extensively distributed in terrestrial and aquatic environments and recently BMAA was detected in temperate aquatic ecosystems, e.g. the Baltic Sea. LÄS MER
5. Foodborne Virulence: Staphylococcus aureus Enterotoxins A and D
Sammanfattning : The development of new, minimally processed food products challenges traditional concepts of food safety. How pathogenic bacteria behave in these new matrices is not known. To fill this knowledge gap and enable the production of food that is safe for the consumer, more information on virulence expression of pathogens in food matrices is required. LÄS MER
