Última Métabolisme et interactions bactériennes en lien avec la vitamine B12 chez la microalgue haptophyte Tisochrysis lutea ArchiMer Nef, Charlotte. Vitamin B12 is an enzymatic cofactor that enables methionine synthesis and whose availability can control phytoplankton development in marine systems. This vitamin is synthesized only by select species of bacteria and archaea. Haptophyte microalgae form a widespread group with major ecological importance. However, little is known about their utilization of vitamin B12 nor their interactions with B12 producers. Our main objectives were to characterize mechanisms of acquisition and utilization of vitamin B12 by Haptophytes and the effect of B12 limitation on their metabolism by considering the model species Tisochrysis lutea. Analysis of the repartition of B12 dependency in haptophytes by molecular approaches suggest that this group would be the first to...
