sulphur cycle

sulphur cycle

the collection of biological processes through which sulphur circulates in the biosphere, from its uptake as sulphates by plants from the soil, its assimilation into the plants and animals, through its release back into the soil and the atmosphere as a result of the degradation of organic matter by bacterial action.

In the article titled "Structural Stability, Transitions, and Interactions within SoxYZCD-Thiosulphate from Sulfurimonas denitrificans: An In Silico Molecular Outlook for Maintaining Environmental Sulphur Cycle" [1], we found three sentences that need to be modified in the third section: Results and Discussion.
In addition to this, there are two major anthropogenic factors which have disturbed the natural sulphur cycle e.g., massive fossil fuel combustion which yield a massive quantity of sulphur dioxide in the atmosphere.

The main primary producers were anaerobic phototrophic bacteria and, as happens in the Ciso pool, during much of the year, the sulphate-reducing bacteria closed the sulphur cycle. This pool is thus an excellent model to interpret the ecological relationships that arose between different microorganisms in the earth's aquatic ecosystems 3,000 million years ago.
However, the new findings also mean that the atmospheric sulphur cycle is more complicated than we thought," says Hakan Svedhem, ESA's Venus Express Project Scientist.
Sulphur cycles sulphur through the land, atmosphere and living things and plays critical roles in both climate and in the health of organisms and ecosystems.
