Where did the universe come from? Atheistic origin science has no answer.

here's some examples.
The bacteria take zinc and sulfur from the water and combine them to create a byproduct of sphalerite--the sulfide usually reacts with metals such as zinc to create insoluble products.

Sulfate-reducing bacteria can be traced back to 3.5 billion years ago and are considered to be among the oldest forms of microorganisms, having contributed to the sulfur cycle soon after life emerged on Earth.

Seriously, now... what does organic (the sulfur kind) chemistry has to do with breaking down heavy metals?
A metal is an element in the middle part of the periodic table, the further down the table, the heavier it is.
Breaking down any element, you get lighter elements and the most common element that undergoes such breaking down is Uranium-238... well, not really, phosphorous is probably much more common, as you can find it in clay which make up bricks and can be found in every construction site, but it's not a metal.

But you were talking about sulfate and sulfide, both compounds which have sulfur in them... along with other things.
Sulfide is S^2-, which is just an ion of sulfur with 2 extra electrons, ready to combine with some other ion with a deficit of electrons.
Sulfate is SO4^2-, a molecular ion, also with 2 extra electrons.
What do these have to do with breaking down heavy metals?

referenced bacteria (sulfur-reducing) because they have made economic mining of ores possible since bacteria coalesces minerals in high concentrations. one reason life thrives on earth is because of its low sulfur-water ratio, mars doesn't.

not sure why bacteria's role in preparing the earth for life by reducing the toxicity of heavy metals is controversial.
