Microorganisms play an important role in the global cycle of various elements such as sulphur, nitrogen, carbon and iron. Sulphur occurs in variety of oxidation states with three oxidation states of −2 (sulphide and reduced organic sulphur), 0 (elemental sulphur) and +6 (sulphate) being the most significant in nature.

Sulfur Cycle Sulfur (S), the tenth most abundant element in the universe, is a brittle, yellow, tasteless, and odorless non-metallic element. It comprises many vitamins, proteins, and hormones that play critical roles in both climate and in the health of various ecosystems.
Sulphur is a common sublimate from volcanic gases associated with realgar, cinnabar and other minerals. It is also found in some vein deposits and as an alteration product of sulphide minerals. Pagano (2002) reported laboratory grown sulphur crystals on white Sicilian matrix.
Underground mining affect the health and safety of miners due to explosions, inhalation of coal dust etc. Burning of fossil fuels releases particulates, trace elements, hydrocarbons, sulphur and nitrogen compounds to air causing huge air pollution. Most important pollutant caused by coal combustion is SO2. SO2 gets oxidized to H2SO4.
Sulfur or sulphur is a chemical element with symbol S and atomic number 16. It is abundant, multivalent, and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S 8. Elemental sulfur is a bright yellow crystalline solid at room temperature.
The last mine operating in the United States closed in 2000. A Frasch mine in Iraq closed in 2003. Sulphur that is mined or recovered from oil and gas production is known as brimstone, or elemental sulphur. Sulphur produced as a by-product of ferrous and non-ferrous metal smelting is produced in the form of sulphuric acid.

chemical reaction. Nitrogen is currently produced in over 78 countries worldwide. The primary raw material for nitrogen production is natural gas, but nitrogen can also be produced from coal, fuel oil and naphtha. The production of phosphate and potash fertilizers begins at the mine. The manufacture of phosphate requires phosphate rock and sulfur.
Sulphur. Sulphur is a multivalent non-metal, abundant, tasteless and and odorless. In its native form sulphur is a yellow crystalline solid. In nature it occurs as the pure element or as sulfide and sulfate minerals.
- Sulfur In table 261 we see that for a crude shale oil the sulfur distribution is rather uniform throughout the boiling ranges but that nitrogen is more concentrated as the fractions get heavier.
