There are quite a few species that can use selenate/selenite concomitantly with sulfur, and producing reduced sulfur species (both inorganic and organic one; some organic S species are pretty smelly). For example,
Rhodobacter sphaeroides (a phototroph),
Sulfurospirillum barnesii (a mesophilic bacterium),
Pyrobaculum arsenaticum (a thermophilic archaeon).
These papers will give you more info on the microbes, isolation methods, and growth media.
