This is significant because here on earth, microbes transfer electrons from metals like Iron and Arsenic and transfer them to Sulfur Compounds in order to extract energy. This is analogous to the way our cells transfer electrons from sugars to Molecular Oxygen.
One of the intermediates of the electron transfer to Sulfur Compounds is this kind of Sulfur crystal. In habitats like mine runoff or deep-sea hydrothermal vents, this specific kind of sulfur crystal is directly associated with communities of microorganisms that create and metabolize them.
