– we learned that the DIET donor partner requires pili whereas pili are not as necessary for the well being of the accepting partner.

-we hunted for DIET type of associations in the coastal sediments of the Baltic Sea. We learned that Baltic Geobacter-Methanosarcina consortia survived only in the presence of conductive particles, unlike lab-consortia of related cultures species. This conductive particle-dependent consortium produced significant amounts of methane. Conductive particles could increase in coastal areas due to the erosion of land/rocks following excessive agriculture and global warming effects. Conductive particles enable syntrophic associations with enhanced methane-activity. Thus mineral-syntrophy could be a key to enhanced greenhouse gas emissions,  and an unwelcomed positive feedback trigger for global warming.
