... similar vesicles loaded with mannitol,Cl – or oxalate 2– . The stimulation of 65 Zn 2+ uptake by intravesicular sulfate was SO 4 2– concentration dependent with a maximal enhancement at 500 μmol l –1 . Zinc uptake in the presence of ATP was proton-gradient enhanced and electrogenic, exhibiting an apparent...

... aggregations, microbes produce sulfide by coupling sulfate reduction with hydrocarbon oxidation. L. luymesi acquires sulfide from the sediment using a root-like posterior extension of its body that is buried in the sediment. Its symbionts then oxidize the sulfide to produce energy for carbon fixation...
