None of the sulfide ions make any favorable hydrogen bond to the protein.
A lot is known on the molecular mechanisms of amino acids on oxides and silicate minerals (and very little on sulfide minerals).
The easily worked oxidised ore was largely depleted and the underlying sulfide deposits were proving difficult and costly to treat.
In addition, hydrogen sulfide can be released from the waste water, potentially resulting in a hydrogen sulfide build-up in the sewer atmosphere.
A moment of the iron sulfide nodule is 100 times stronger than black shale.
When acetic acid was poured over the produce ("liver of sulfur," which contains mostly potassium sulfide), sulfur precipitated due to an oxidation of the sulfide.
We are studying microbes in hydrothermal environments that obtain metabolic energy from mineral substrates, particularly metal sulfides.
This was probably due to increased precipitation of the sulfide with iron.
