eng	Autotrophic denitrification using Thiobacillus denitrificans - comparison of batch reactors and flow-through reactor	Thiobacillus (T.) denitrificans belongs to group of chemolithoautotrophic and facultative anaerobic microorganisms. It is widely distributed microorganism, found in soil and water habitants. In terms of environmental, these organisms are very important - they can be used in processes of alternative methods of removing nitrates from contaminated water. T. denitrificans can obtain energy by the oxidation of elemental sulfur and certain other sulfur-containing inorganic compounds while electrons are released. Under anoxic conditions, nitrate and nitrite ions are reduced by these electrons and molecules of nitrogen gas are formed. In this work, we focused on the comparison of denitrification processes in batch reactor and flow-through system and on the comparison of optimum conditions for bacterial cells and denitrification processes. For all experiments, the elemental sulfur was used as electron donor.	Thiobacillus denitrificans; microorganism; denitrification
