Phytoplankton and Thiamine
Have you ever heard of thiamine deficiency? A high mortality among animals due to thiamine deficiency has recently been observed and the cause has been proposed to be phytoplankton. These are the main producers of thiamine out in open water and the share of thiamine auxotrophic phytoplankton, plankton who are unable to produce thiamine, is likely to affect the deficiency.
In this project it is examined how the concentration of phytoplankton in water from the Baltic Sea changes upon addition of thiamine. The results indicated a substantial share of thiamine auxotrophic phytoplankton when and where the samples were collected. With more knowledge about phytoplankton communities we would be able to improve the conditions for aquatic ecosystems.
