Around half of all extant species of microalgae require an exogenous source of vitamin B12 . Prokaryotic organisms are the only known synthesisers of vitamin B12 and recent work has shown that some species of algae can form symbiotic interactions with these bacteria in order to satisfy their requirement for the vitamin. During this seminar recent research which has been done in this field will be detailed and I will highlight three unknown aspects of this work that my project objectives are based on. These include determining the role of cell wall proteins during vitamin B12 uptake in the Volvocales order of algae, characterising possible communication molecules used between algal and bacteria cells during mutualistic symbiosis for the vitamin and identifying a marine model for the algal-bacterial symbiosis.
