Iines Salonen pub­lishes new study on foraminiferal endobionts in intertidal mudflats

The study discovered enrichments of sulphur cycle-associated bacteria within foraminifera, indicating that these bacteria may play a role in the metabolism of the foraminfera host.

On August 12, 2019 ABRU and MERG PhD student Iines Salonen published her most recent paper "Enrichment of intracellular sulphur cycle –associated bacteria in intertidal benthic foraminifera revealed by 16S and aprA gene analysis", in the journal Scientific Reports. In the study, Iines and her colleagues analysed benthic foraminifera from intertidal mudflats of the Wadden Sea using a metabarcoding approach targeting the 16S and aprA gene. They discovered that the foraminifera have an enrichment of intracellular sulphur cycle-associated bacteria. In the past, these sulphur-cycle related putative endobionts in benthic foraminifera have been largely overlooked and understudied. However, as in this study shown, there is now reason to believe that these bacteria infact could be linked to foraminiferal metabolism. Nevertheless, fruther studies targeting the activity of the putative endobionts are needed to confirm their functions and roles in foraminiferal ecology.
