Noteworthy
This paper describes the highly evolved interactions between anaerobic protists and their syntrophic sulfate-reducing symbionts. Remarkably, the symbionts reside in an elaborate symbiosomal membrane network that places them adjacent to both the host's hydrogenosomes and the extracellular milieu, where they can access sulfate. The physical properties of the symbiosome ensures the efficiency of the syntrophy. (See the paper for figure explanation.)
