Anotace

V originále

Sulfur is an essential chemical element for all living organisms. Microorganisms can utilize reduced and oxidized sulfur, preferably sulfate because it can be easily utilized in their biological processes. In this article, the most notable pathways: assimilatory sulfate reduction, dissimilatory sulfate- and sulfur reduction were described. The resulting compound from all three pathways is toxic hydrogen sulfide. It has a negative impact on human health, the environment and due to its corrosive properties also limits some industrial processes. The chemical methods of its removal are costly; therefore, the biological methods are researching as an alternative. The promising organisms are phototrophic green and purple sulfur bacteria. They oxidize hydrogen sulfide present in the environment, resulting in the creation of elemental sulfur.
