Organism

Organism UniProt Comment Textmining
heterotrophic bacterium
-
 two bacteria designated A-50 and C-3, isolated from percolation units containing garden soil and elemental sulfur, the enzyme system in C-3 is constitutive, but in A-50 it is induced by thiosulfate or tetrathionate

thiosulfate + oxidized acceptor A-50: once induced to oxidize thiosulfate, also reduces tetrathionate to thiosulfate in the presence of an electron donor such as lactate, the possibility cannot be excluded, that a separate tetrathionate-reducing enzyme is induced heterotrophic bacterium tetrathionate + reduced acceptor
