With a much-discussed vitamine in focus
Name: Emil Fridolfsson
Emil Fridolfsson is a PhD student within EcoChange at Linnaeus University. He is tackling a much-discussed topic: the vitamin thiamine. Lack of thiamine has become a problem for salmons, eiders and many other marine species. Emil is trying to find explainations to the proved deficiencies by studying phyto- and zooplankton.
What is it you are working with?
I am studying the much-discussed vitamin B1, thiamine. Thiamine is produced by bacteria and phytoplankton, and is important for zooplankton, fish and all other organisms. In my research I focus on what happens in the food web, how thiamine is produced, and how it is transported through the food web. I study variations in production and content of thiamine over time and at different locations in the Baltic Sea and the Swedish west coast. My work is carried out at sea as well as in the laboratory.
How did you get interested in this research area?
I have always been interested in aquatic ecology, and I have been working with phytoplankton ever since I took my Masters degree for Professor Catherine Legrand. When Samuel Hylander started up his research at Linnaeus University he initiated a project about thiamine. Fortunately, I got the opportunity to continue on that path.
So how does your research link to EcoChange?
Thiamine deficiency can led to reproduction disturbances in Baltic Salmon, but it is not yet explained how and why these disturbances occur. Large scale changes in phytoplankton populations could be important, and these disturbances could be caused by climate change.
What are your plans for the future?
First of all I will complete my PhD studies. We’ll see what happens after that, but I would for sure want to go on with research. It is such an exciting environment, where you learn new things every day.
Good luck with your thesis work!
