دور العوامل البيئية و بكتيريا Acidithiobacillus في تآكل الآثار الصخرية و المعدنية

الملخص EN

Sedimentary rocks contain various traces and fossils, including metal traces of different forms, as well as various elements such as iron, sulfur, copper and many others.

It is surrounded by the atmosphere and the various environmental factors that affect it and interact with it negatively or positively, such as temperature, humidity, acidity, air pressure or load pressure, as well as living biological factors such as algae, fungi, and bacteria.

Speaking of iron, sediment rocks form in the form (FeO or Fe2O3) or form FeO(OH)nH2o = Limonite or HFeO2 = Goethite.

Acidithiobacillus bacteria are classified as Gram-negative, meaning they have a relatively high resistance to environmental conditions and other harmful substances as well as antibiotics.

The conversion of hydrogen sulfide to sulfuric acid inside the concrete pipes, causing corrosion.

These bacteria use the element sulfur and iron ions as a donation of electrons, digesting carbon from the sulfide of dimethyl sulfide or dimethyl sulfide or disulfide carbonate to carbon dioxide.

These bacteria are strong filtration and washing to convert elements from their solid form to liquid form, they sabotage rocks containing sulfur or iron, as well as metal traces made of iron and copper, which are found within the layers of sedimentary rocks.
