Well basically, the bacteria reduce sulfate to hydrogen sulfide:

SO4(2-) + H2O + e(-) --> HS(-) + OH(-) (i'm not gonna bother balancing)

which provides a pathway for the electrons released in the oxidation of iron:

Fe --> Fe(2+) + e(-)

is that like the anaerobic (or however it is spelt) bacteria?

 

[ND]

Yep.
