A kinetic study on nonoxidative dissolution of sphalerite

The dissolution rate of sphalerite is of the first order with respect to the hydrogen ion activity of the solutions. It is also considerably affected by the iron content of the sphalerite sample; a linear relationship was observed between iron content of the sphalerite and its dissolution rate.

Ecology, Diversity, and Evolution of Magnetotactic Bacteria

Is the Known Diversity of Magnetotactic Bacteria an Underestimation? MTB are ubiquitous in freshwater, brackish, and marine habitats, and many different cell morphotypes can be present in relatively large numbers in collected samples of water and sediment. Until recently, only MTB in relatively large numbers in samples (e.g., "Ca.

Hydrogen sulfide S or S8 PubChem

Hydrogen sulfide is a covalent hydride chemically related to water (H2O) since oxygen and sulfur occur in the same periodic table group. It often results when bacteria break down organic matter in the absence of oxygen, such as in swamps, and sewers (alongside the process of anaerobic digestion).
