This is mostly wrong. Sulfate is the electron receptor, not the donor.
I'm not sure but I think the electrons are obtained from hydrogen gas,
which is produced in a fermentation reaction. The noticable products
are reduced sulfure compounds, including hydrogen sulfide and some
sulfur-bearing organics. Those stink.
