Bacterial decontamination of soil from Ostrava Airport
(Wydawnictwa AGH, 2009) Fečko, Peter; Tora, Barbara
The paper deals with an examination of possible application of biodegradation in the decontamination of soil samples from Leos Janacek's Airport in Ostrava. Soils samples were used for laboratory tests of biodegradation taken from oil interceptors. The laboratory biodegradation tests were carried out with a pure bacterial culture of Pseudomonas putida, a pure laboratory culture of Rhodococcus sp., their mixture and a mixture prepared combining their media free of bacteria. The results of the paper imply that for the given purpose, i.e. for biodegradation of airport pollutants, it is most suitable to apply a mixed bacterial culture of Pseudomonas putida and Rhodococcus sp. The results of the paper show that the biodegradation method is applicable for the pollution in question.

Bacterial desulphurization of coal
(2006) Fečko, Peter; Pečtová, Iva; Čablík, Vladimír; Riedlová, Silvie; Ovčaří, Pavla; Tora, Barbara
The aim of this paper is to evaluate the suitability of a coal samples from different mines from Poland and Czech Republic for bacterial leaching. Laboratory research used a pure bacterial culture of Thiobacillus ferrooxidans. Were tested the samples from this localities: Mine Marcel, Mine Jankowice, Mine Staszic (Poland) and Mine Darkov and Mine Dukla (Czech Republic). The results showed that bacterial leaching was effective, with one month leaching time, when total desulphurization is from 38% to 72% and desulphurization of pyritic sulphur is from 60% to 82%. The paper describes changes of coal macerates after bacterial leaching.

Badanie zależności podatności na mielenie od wybranych parametrów węgla kamiennego
(Wydawnictwa AGH, 2010) Tora, Barbara; Fečko, Peter; Nowak, Alicja; Tajchman, Zbigniew
One of the characteristic of coal which is important in energetic is coal grindability - use of energy needed for milling. This paper focuses on investigation of dependence of coal physicochemical characteristics on grindability (Hardgrove index). 21 samples from Poland, Czech Republic, Russia and Colombia were examined. It was noticed that grindability depends only for coal which origin from one deposit.
